Some people might experience with certain GPS software.
If you look at the log of the NMEA log, you might realize that it burst out every 6-10 seconds. After that you might wait for another 6-10 sec, which is unusable for real-time navigation. If you happen to meet this trouble.
I have a way which could allow normal update intervals.
Install GPSGATE, it create virtual GPS COM PORT and re-route the NMEA data.
Install GPSGATE, just use the default settings, it create the virtual GPS port as COM 1.
Just use GPS software on COM 1 .
software url: http://franson.com/gpsgate/
Can anyone confirm this works? Ive noticed my GPS works the same way. Im using the Kaiser / TyTn II with Mapking and i notice that i also get my signbal ins bursts and NOT a smooth stream. Anyone know if this will resolve the problem?
What is the update intervals with GPSGATE ?
Do you mean GPSGATE must be run concurrently with the other software TomTom 6 for example ?
It would be a good workaround for people who encounter this GPS issue.
could this be some delicious spam?
How exactly does the OP propose that a user space application can make the hardware produce data in a smoother stream?
I call BS.
seems like BS to me too...Probably some spam Can anyone who has tried it out verify if it really works or not?..
THKS
You don't need to use other GPS software concurrently,
just use the GPSGATE and mapking will do.
Remember you have to modify the settings in mapking to use the virtual com port ( com1 default)
Not SPAM
I am not sure, this is BS.
If I am not mistaken the GPSGATE will act like a "router" (middle man) between the GPS hardware (Internal GPS of Kaiser) and the application (TomTom).
If the GPS hardware is faulty (having problem) with bursting data every 10 seconds, then the GPSGATE will also receive bursting data every 10 seconds.
So, that's useless as long as the problem is in the GPS hardware.
Gpsproxy should be able to do the same thing and its free.
GPSGate is a splitter, allowing using more than one application with the same NMEA stream. It creates another virtual GPS COM port, that's it.
GPS on the Kaiser works great and I'm on SatNav business. Aquisition time is fast, reception is great and update ratio is every 1 sec, just like any other civilian GPS receiver. GPS is NOT evaluated by the refresh rate you see on the screen, other software will give you other rate, try OZI Explorer for instance. I used Kaiser with TomTom, Destinator & Ozi, all works really great even comparing to Sirf III GPS chipset embedded devices such as Eten X500, HTC Artemis and Asus 535.
Last, Microsoft has included the same functionality of GPS Gate in WM5 and WM6 under settings. You do not need to install any additional SW, you can send "trueman 12345" (the guy who opened this thread with 2 posts history) your money directly.
Thanks RonenB for this very usefull precision !
Thanks as well RonenB, However, it does not solve the odd occasional pause in the data that we're seeing. Is this hardware or software that needs help in the Kaiser?
Actually I'm not so sure we have defined the problem accurately here.
Examining the signal from the GPS shows some interesting info.
1
A satellite is locked onto for perhaps only one or two seconds at a time.
2
Several satellites can achieve a lock but out of these a few will be lost every few seconds
3
New satellites are also acquired every few seconds.
The Result
If you are in the presence of many satellites then there is a constant dropping of some and locking onto others. This leads to no problems as there are always a few satellites locked on and data flow is smooth.
BUT
If you are in the presence of only say 2 or 3 satellites it is possible to drop these two or three (as indicated above), but no new ones are acquired. In this situation there will be a few seconds before the first 2 or 3 lock in again. Result a gap in data flow to your GPS software.
Meaning
The Internal GPS is not polling data in bursts. In other words you cannot turn up the frequency of data polling (possible baud rate adjustment maybe). The data is continuous but if there are too few satellites then there can be gaps where it drops some satellites and does not lock others.
There are various applications that can show this behaviour graphically but tomtom shows it well on the satellite view screen.
Compared to external GPS satellite locks this works in a strangely different way. You will see the bars jumping around from a lock on this one to that one continuously. Only a problem as I say when there are only a few satellites in sight.
Mike
PS - I cannot see the advantage of GPSGate in this particular situation as it is due to momentary periods when no satellite is detected.
Having said all of the above, I find the GPS perfectly adequate for general use. Perhaps if I need spot on plotting data then it might be weak. However if I need that unusual level of accuracy I would not use my phone to do it. I regularly use mine in place of my car's tomtom and the results are on a par with the full tomtom device.

Ok, I believe that it is time to explain a little bit how GPS works.
The GPS satellites are transmitting their position rapidly. However, due to homeland security issues (US did not want to allow anyone to place a receiver in a jet fighter or a missile) civilian GPS receivers are limited to aquire position every 1 second only. This is not a problem for a normal user even for civilian aviation. Thus, when you look at the NMEA stream, you will see it coming in bursts and not as rapid as normal data. Since GPS strings are quite short, it is good enough for any navigation system.
Number of satellites aquired is not an indicator to anything. Like any RF system, the engineers can tweak the noise level so that it will look to you that you are receiving X amount of satellites, the signal is on the air anyway.
What is important though is the position of the satellites. the closer to the horizon, the less useable that satellite is to calulate the position. Therefore receivers are taking the best located satellites into account and ignoring others even of they are recieved. Valid fix (position) is aquired by at least 3 satellites for 2D (X,Y) and 4 or more for 3D (with elevation).
Result is that as a user, you should not bother too much looking into the stream or number of sattelite in use as long as you can get a valid fix. The important and effective elements are hidden from the user: number of transsistors in the GPS chipset, quality of antenna etc. User can just evaluate the overall preformance.
As I wrote above, the Kaiser integrated GPS surprised me for superb preformance. I just arrived this week from Israel to Germany and could get a fix as soon as I left the underground garage. I did not loose GPS signal even once since I started using the device. That includes forests and dence city centers. Real good job by HTC here.
This is the problem i am facing:
Im using MapKing with Hong Kong 2007 maps. Getting a fix is no problem. I can normally get a fix in about 10-15 secs. When i check the status page I will normally have a connection to 5-7 satelites.
The problem is that the icon does not move smoothly when i travel. In map king your position on the map is represented by a small car icon. It jumps from location to location every 3-5 secs but does not smoothly move along. Can someone please tell me if this is the case with tomtom as well? Maybe it a problem with mapking?

It is a Mapking problem and you should contact their support. Does not happen to me with Destinator, TomTOm and Ozi.
Ok, there is no point to argue, if you really find yourself having problem with GPS update lag, then give it a try. No harm indeed...
In HK, there are people the validity of the work around. GPS proxy might also work as well( i think it is the same principal) just i wasn't aware of this good free software before hand..

FYI: I got GPS to work easily by installing GPSViewer, opening COM4/4800baud and getting located. After that, using Google Maps was a breeze; total "trick" took me about 1 minute to figure out which is way quicker than some other workarounds on the internet.
I was driving with iGuidance for about 1 hour this morning and I'm seeing different behavoir for this bug. iGuidance also has an excellent GPS signal viewer, mine was showing 8 out of 8 sattellites, all green, all the time (they turn red when not receiving signal from a sat). My map was moving about once per second or slightly faster. The program only paused once after about 30 minutes into the trip, for about 20-30 seconds. The iGuidance program's moving arrow's color also changes color based on signal quality of the combined sattelite lock, Green for good 3D mapping, Yellow for 2D when there are minimal sats for navigating, and Red for no signal data. During this pause the arrow went Red to indicate no data.
This seems like a bug to me.
It doesn't work with any application. Do i have to turn on the internal gps somehow?
Please help me.

Go to this page and see the link for external mirror 1. use it to download GPS TEST:
http://handheld.softpedia.com/progDownload/GPS-Test-Download-34335.html
or get it here:
http://classic.pocketgear.com/softw...ssociateid=1224
When you have installed it, run it and it will auto scan the ports to find the GPS receiver. Make note of the port number - that's the one you'll need for your other applications (like tomtom etc). Make sure you have a clear view of the sky when running it and give it PLENTY time to achieve a first time fix.
By the way if you have ever used the "External GPS" on the Kaiser then you may have altered some settings that can stop GPS working. Unfortunately only a hard reset will cure this. BUT, try the above first. If GPS test can get satellites then so will other applications.
This little application GPS Test is also useful to run before things like Google Maps that some folks have problems with.

Ok. If GPS test works and finds sats then, you have an incorrect port set on the other applications. From GPS Test see what port it has found the GPS on. Then in tomtom say, use "other nmea device" or "internal GPS" whichever option it has in the "configure" menu and set the port to the one noted from GPS test.
Fact is that if GPS test finds sats then everything is working and its just getting the link between the GPS and the nav software that needs fixing.

I just had to leave my house and try it on the road. Now it works everywhere. YEAH!!!!!!!!!

this works, but why do we need to run gps test before any gsp app? is there not a reg key that will be able to fix it?

I used to have the same exact problem...Google Maps just gives up if it doesn't find a fix right away. TomTom does finally get a lock without GPS Test, but it takes less time if you have GPS Test running beforehand.
I had the same problem .. GPS would not work with Google, MSN live. Downloaded GPS test and still nothing. I finally did a "hard" reset (painful, but I did have everything backed up on my PC with Active Sync).
After the hard reset GPS worked GREAT! I must have messed up a setting trying to get it to work. GPS test now reports that the GPS is active on COM4, 9600 baud.

You don't have to run it before every GPS application. Some folks find Google Maps benefits from doing this but I only suggested running the GPS test app to establish which port was being used. Even with Google maps you may find on subsequent occasions you do not need to run an app like GPS Test first.

does anyone else have the problem where tom tom doesn't show the correct position it always thinks i am about 20 - 50 meters to the left of my real position.

I don't have that problem - even when I have few fixed satellites. However I did read a report recently where someone routinely had the arrow showing 200mtrs away from his position. Sorry to say it was only after a Hard Reset that the problem vanished.
As a side issue. I have noticed with tomtom and any other GPS software -
If you start the GPS software in an area with no or poor GPS signal, then it will take FAR longer to get a fix EVEN when you go into a clear sky area.. If however when you start the GPS software in a good open sky area then it will fix much more quickly.
The moral of this story - don't start the GPS when you are inside a thick walled building - wait until you get outside first. I'mguessing that starting in an area with a very weak signal sends it searching in all the wrong areas for satellites and it will then take a long time to find them even when you get outside. (This is true, I have noticed with all GPS systems I've used not just the Kaiser.
Mike
FYI, I have found that Map4PDA breaks the GPS. I believe it changes the baud rate to 57600, which is incorrect (it should be 9600). The only way to fix it I have found is to Hard reset and not install Map4PDA.
TomTom, Micrsoft Live Search (with Speach), & Google Maps work great. Features set in that order.
PS that GPS test tool works GREAT. Thanks for the heads up.
I noticed like most that the assisted GPS is switched off be default out of the box. I decided to switch it on today and while using Tomtom I noticed every 2-3 seconds the gps signal would come on and off. It was just as though the GPS receiver did not exist. I tried a soft reset without luck. As soon as I disabled AGPS, Tomtom functioned perfectly.
Any suggestion on what could be the cause or did HTC deliberately disable AGPS because there is some problem with it?
Thanks
could someone possibly swtich on their assisted GPS and let me know if it holds the sats with tomtom

Have just done as requested on my device (using Advanced Config to enable it) and can confirm I see identical results as you;
- Assisted turned OFF (out of box): works fine
- Assisted turned ON: works for a few seconds, "No GPS device", works for a few seconds, "No GPS device", and so on
Also, I have found that no matter whether the above is turned on or off I am unable to get a position fix indoors (ie. next to window) - something I believe A-GPS was supposed to be able to do?
Very strange.. not least that it is disabled out of the box? Ideas anyone?
I've just received my diamond so I haven't tried it outdoors yet, but I can confirm that it's practically impossible to get a signal indoors with a-gps on. I turned it on first, so haven't tried it when it was off. Other gps receivers didn't have that much trouble to get reception near the windows. Will test some more outdoors with gpstuner which shows some more info than tomtom.

I agree with you as well. Today I was using Destinator 7 and had the exact same problems. It's like instead of using sat navigation, it's using the GSM signal and thus the map moves every 100-200 meters after the car has passed. Once the A-GPS is off, the program is flawless
Where do I turn on A-GPS? Is it the same as QuickGPS?
Same problem I had when I tweaked with Advanced Config... quickly figured that was the cause and turned it off.
It's quite quick and acceptable with sat locking so its no biggie.
I also think that the program that comes with the diamond to download a map of the sats helps a lot more then agps.
testing on my D-nd with TT and Garmin
it will work if you set the baud rate in TT to 2400. Otherwise turn agps off and it works at the regular setting. Haven't really notices a difference in performance one way or another.

Thanks for the above tip.
Have just made the baud rate change, and will test whether or not it works for me on my way home this evening.
However what I can report is that I am unable to get any 'lock' indoors (however approximate - ie. TomTom is reporting the normal "no valid GPS signal"), this being one of the benefits I thought A-GPS brought (ie. using phone mast information to provide an approximate fix when normal GPS was unavailable / weak). Has anyone actually provided the "A-" is providing benefit???
Well, I don't get it. When you setup the internal gps on Tomtom Navigator 7, you set it to internal gps receiver i guess. Doing it this way don't give you the option to configure the baud rate or so.
Setting it up like this, and i guess this is the correct way, you can't use asissted gps. You can get a signal from the gps, but it keeps on dropping it.
Hopefully there will be a fix for this problem. Till now, if you completely disable a-gps, e.g. through advanced config, it all works perfectly.
Hi all,
Could you please, be kind and post you experience with TD's GPS...
Since I got my TD(4 days) I have not been able to test the GPS at all
I have loaded some soft that could help me here. ( I travel a lot between Korea and Japan). Cannot really use the phone here, but WIFI works great and I thought I would give the GPS a test run.....no luck YET..
TD's own: QuickGPS has downloaded(through WIFI) all the info and it is up to date......But how do I set up the GPS itself???
Phone did not come with preloaded GPS software so,I have loaded following soft on itnone of them would recognize the gps)
i.e. " no GPS found."
1.Google Navigator 3.4
2.GPSvp (http://gpsvp.com)
3.Effica GPS Utilities (http://www.efficasoft.com/gpsutilities/index_wm_ppc.html)
I would really like to test out the GPS here first.I am returning to EU (home) in october or november and I would like to use it there as well.
sorry for the bump
I tried the search...not just this forum but all of XDA.....I cannot seem to find one successful step-by step activation as of yet???
Nobody has internal GPS running on their TD??
Anyone?
Runs perfect and is good quality.
Make sure you let windows manage gps (in external GPS settings):
programport COM4
hardwareport none
and in last tap check the checkbox.
Programs find gps at Com4 at 19xxx baud.

Don't you have a problem with the static navigation? This behavior "drives"
me nearly crazy, because beside of that, the GPS in TD is superb...
On mine, no programs can access the GPS and the programs will lock and crash the phone when it tries to connect to GPS.
The onlt one that does not lock the phone is TomTom, but it wont connect to GPS.
I've tried combinations of the recommended port stttings, but I still get no GPS.
I have not activated A-GPS, so I don't know if the phone came with this already activated - how would I check this?
My GPS is a pain in the arse, From what i have read its because of the static navigation. So far it says i live in house number 20 when I live in house number 16 and when i'm on route I'm yet to hear a " You have arrived at your destination" because its accuracy is off about 50 metres.
Hopefully there will be a fix for this very soon.
can someone get me up to speed a bit? what is the 'static navigation' that i keep hearing about..
admittedly, i find sometimes the gps is slightly less accurate at placing my exact location compared to my old Trinity, but otherwise its worked great for me..

Hey, have you got installed TomTom 7? I'm running TT7 and when I select "internal GPS receiver" it connects perfect. I know this doesn't exist in TT6, but I can also get my GPS running in TT7 if I set it to use a BT receiver on COM4 at 57600 baud. (Assuming you didn't mess around with the standard GPS settings, like HTC meant them to be )
Google maps is using the selection of "use windows settings".

hi guys
Same problem here. AGPS is disabled. I have tried Garmin,TomTom, iGo and google. 95% of the time it can not lock onto the sats. Once in a while it will work fine. Last night it picked up the sats in my bedroom on the second story and this morning outside in clear sky it found 4 sats but with very low signal and could not give me my cordinates, gave up after 15 min.
I have tried GPS tools and even that won't lock onto the sats. Data is upto date with quick gps.
So is it the hardware problem or has it to do something with radio? It can't be faulty TD because there are a lots of people with the same problem, and why lots of other users have no problems accessing the sats?
How is your gps working?
hi
great going sofar...thanks to all. We still have no real answers.
Let's keep this one going.
Looks like GPS is an issue with TD.
( Other than GPS...I am loving this sweet phone )
Now I am trying different roms to see if it is related to that. Will let you guys know if find anything.
Strange, on all ROMS my GPS reciever just works perfect.
Almost the best piece of hardware on the device
As I mentioned in Another topic, I use the GPS for TrackMe, at the same time I am navigation via Igo, and at the same time I showoff Google Maps with GPS support.
It functions very well!
Did you get the GPS-Fix downloads? It speeds up a lot.
Yes got the gps fix downloads but still no go. Still have not lost the hope. I hope its not some hardware problem.
I was fed up messing with mine, so I did a hard reset, and its sorted ...... for now!
same as Paulus
I did a hard reset....and it works perfect. No other adjustments done.
Tried the TomTom, Tracky Pro, GPS VP, and the HTC GPS Tool....all work no problem...outside I get a fix within a minute sometimes seconds.
I think one of the quirks that the TD's GPS has is that, when it's in Acquiring Satellites mode it doesn't seem to spit out any sort of status. The first time I noticed that I thought my internal GPS wasn't working, since with my external Holux unit I can see the satellites which the Holux was trying to lock onto.
Whereas with the TD's built in GPS it just snaps from nothing to.. acquired. So it's hard to see wheter it hasn't gotten a signal because it's in a poor area of reception or not. Usually I'll just try and stay still till I can get a lock.
Hi,
Like most people here, I've experience TomTom's lag. From my stock Touch Pro, I notice a 3-4 second lag whilst driving around 60km/h. I read the previously mentioned GPS tweaks for the Touch Pro and initially applied the tweaks, but only dividing the original values by 4 (eg. PollInterval went from 1024 to 256, etc.). This reduced the lag to 1-2 seconds whilst driving. After applying the tweaks by dividing by 8 (eg. PollInterval to 128) resulted in the same 1-2 second lag in TomTom whilst driving. Clearly, the GPS is no longer the bottleneck now.
Next, I planned a route and watched the Demo at 200% speed to see how fast I can expect TomTom to appear. The display refreshed every 1-2 seconds! Coincidence?! I was in Harvey Norman (huge electronics retailer with lots of demo units) and watched a route Demo on a TomTom standalone device at 200% speed. The display refreshed 2-3 times per second.
Hence, is it possible to increase TomTom Navigator's refresh rate on the Touch Pro? For example, by applying some kind of graphics configuration changes or something? Perhaps tweaking the graphics driver somehow? Or is it that the standalone TomTom devices have much better hardware and the performance we are seeing on the Touch Pro is about as good as we can expect it?
Any help appreciated!
Cheers,
Ledg3.
Any ideas? Anyone?
Just wondering. have you tried one of the newer roms that have the gps driver cooked in? i am using provens 1.06 and it seems to not lag as much (only tried it for about 15 minutes earlier today)
Hi ajmoncrief,
Thank you for your reply.
I haven't tried any ROMs at this stage as I received my Touch Pro just recently.
Is it possible to load the new GPS driver without replacing the ROM?
Also, does your new GPS driver lag less than 1-2 seconds whilst driving?
At the moment, I would be surprised as TomTom only updates my display every 1-2 seconds, even just by running a demo (and not relying on the GPS for input).
I'm not sure about a driver cab...I would assume that theres one floating around. Check out Da G's rom thread and qsqa's PROven's thread. I tested tomtom again this morning and I'm getting much better results now. I'm not exactly sure how fast/slow the screen refreshes, but it does do so in a timely manner. Im confident that it does do better than once every 1-2 seconds. (I only live 3-6 miles from everywhere I need to go and I dont have any out of town trips within the next couple of days) Maybe someone else can chip in on their thoughts here.
TomTom 7.9 slow refresh
I am having the same problem on the AMEO (X7500) and TomTom 7.9 - screen refresh is quite slow, every 2 seconds. Version 6 was running realy smoothly. Any ideas? Soft reset, restart, speed camera warning on-off does not change the refresh rate.....

Your position on the map is always going to be a second or two behind your actual position. There is no bottleneck or slowdown even if you set the GPS at 4800 baud. The GPS only sends out a position update once a second. This will also make the screen a little jerky. Most programs smooth out the jerkiness by assuming there will not be a huge change in speed and smoothly move you to where they estimate the next GPS position will be.
Some programs also cheat and estimate your actual position on the map, so it is very close to your actual position. You can tell, because in the city you will be shown going through the intersection when you make a turn. It will then jump backwards and then show you making the turn. One of the GPS programs I use to have did this, but I do not remember which one.
TT7 on my Kaiser (ATT Tilt) moves smoothly along, and is near dead on for location. There's no refresh problems.
TT7 on my Raphael (ATT Fuze) repaints the screen every 1 - 4 seconds, and my position is off by at least 100 feet. Even with tweaks, it functions pitifully compared to the Kaiser.
is everyone here using the VGA version of TT7 or the QVGA version meant for the Tilt?
there are different versions (vga and qvga)??????????
Have you tried Franson GPS gate? DOwnload the trial and create a virtual com port 2 and map the Com4 GPS multiplexer to virtual com 2 and then have tom tom look to com 2 for the GPS. I bet the lag goes away. I was told that the commercial GPS softwares look for standardized GPS info in which the HTC phones' GPS use a variation which causes lag problems.
tomtom 7.910 screen redraw problem
Yes there are different versions of 7.910.9185 blue, black qvga and there is VGA version. I have the problem with the screen redraw, not the general speed, which is better than 7450 for example for route calculation. Screen redraw on 7.450 version was running smoothly, so it is not the question of the GPS, but the maps form 7.910 are not compatible with the 7.450. Screen redraw problem is visible even in demo mode, at 200% of speed instead of the smooth ride you have a "slideshow" in 7.910 version

I was using 7.450 but i read that version was for qvga devices so i upgraded to 7.451 i know it seems stupid for a .001 update but that is vga not sure about 7.910 as i read that it was vga to and for the diamond if im not mistaken but you can try 7.451 if you want. look around for it also if the map works for 7.450 i don't think it will work for 7.451 or at least it did not work for me. so look for the files if you can't find them drop me a pm and i can tell you where to "BUY" them also i tried the gps reg tweaks and it did not seem to make it any better but i did not have a problem with the gps in the first place. hope this info helps
I've also experienced lag like what you guys are talking about... what I did was I disable all POI in preference so that nothing will show up and it seemed to be a lot faster... still has that choppyness... but much better than before... i hope this helps...
Anyone has this 7.450 Tom Tom VGA Cab? Thnx in advance

How sure are you about this solution? Have u tried?
If it works, it means TomTom is at fault here, and not HTC
But it also lags in Google maps....how would you explain that?
I am very curious if anyone has really tried this and can confirm the lag going away (and most important; make pedestrian mode usable)

Sadly the HTC really is fault here, not TomTom. I have a external SirfIII GPS module, and while TOmTOm still appears to redraw 2-3times a second, the lag goes away. And TomTom is very very accurate then. The Franson GPS gate doesnt solve anything with the lag. It might make GPS lokc quicker, but tbh it didnt help me much (using QuickGPS data). I get fast locks with both the built-in and the external GPS. The problem is between the data output and the chipset. Drivers should / or could solve it.
Problem solved!
Hello,
Yes I have been experimenting A LOT with TomTom. I have found out that what really slowes down the map redraw is the RADARS if they are inserted into the map directory as a POI. Without radars it runs very nice both in version 7.45 and 7.9.
TT redraws screen very slow even if you switch off the warning for getting close to the radars as POI categories, I think that it is much too many of them for the whole Europe and POI mechanism is not the proper one for radars. Changing the radars into the official "with serial" solved the situation. I hope it helps to the others!

Aside from the initial startup (I wait about 30 sec) everything seems to work well. Refreshes good, etc.
I use the following settings:
Ver: TTN_7.450.9028
Map Pack: USA_and_Canada_v.675.1409
Other NMEA Device
Baud 19200
COM 4
HTC Radio: Raphael Radio 1.08.25.20M1
I have the AGPS UN-Checked

Thanks for the tip, I just updated to this radio from 1.02.25.28 and my GPS seems to be working much much better!
