Hi,
today I upgraded my htc3600 to test gps version, and gps work's really nice! But I can't find gps on/off button and wondering is gps working all the time or just when gps programs running!!?
Regards
I believe it's auto on off. Because after a certain time if I leave my navigation software off and turn it back on it has to redetect the satellites. But I could be wrong. Then again I don't notice any difference in uptime. Still get about 2 days per pull charge.

GPS will be activated as soon as an application send a request on com-port 9. By default GPS is off. When a program stop listening on com-port 9 the GPS turns off.
Furthermore GPS requires little power usage. In a common Bluetooth GPS mouse the bluetooth radio part consumes most power.
Guys, so can we confirm that it's GPS and not A-GPS? And yes, I'm a rookie in the field.
A-GPS and GPS are both working GPS... it is just that A-GPS also incorporate additional functions which allow position fixing based on cellular network position signal. In fact, A-GPS is better than normal GPS in city environment as it allow quicker and more accurate position fix when compare to just using GPS satellite along. I hope this will make it more clear to everyone regarding A-GPS and normal GPS... they are both the same thing but A-GPS is better for city environment.
Anyway, just my two cents.

Yes, I understand that A-GPS may allow you to get your position quicker because it's assisted by cell towers but what I don't understand is that I don't know if cellular towers must be present for it to work? In other words, can I use A-GPS in the middle of no-where? If not, then I need GPS and need to know if the Trinity has GPS or A-GPS...

In my country, A-GPS is not supported by the mobile operators. However, my trinity doe have functionable GPS, therefot, the GPS will work without celltowers...
(allthough in my opinion, the quality of the GPS recieving is poor at best)

A-GPS assists, it doesn't need to be there for the GPS to work, the receiver just locks in slower without it. You could be out in the middle of nowhere with no phone service but GPS is still sending signals from space and the GPS receiver will work. It would be stupid to have GPS that only worked when there are reliable cell towers...we know how reliable they are .
Hi, anybody with this test rom can do a benchmark for battery life with gps always on and see how long it lasts?

I was under the impression that towers were necessary the way everyone's always bummed out to hear that a phone's GPS unit is an A-GPS one. Glad to hear it's better (?).
I found a link at wikipedia.com that gives a good explanation of a-gps.

I did not a benchmark but my experience are very good.
I drove 2 hours and had a battery drain of 10%.
If the battery drain scales linear it means I can drive 20 hours nonstop.
I think 20 hours is not possible but you can easely drive up to 8 hours on your battery.
Hi,
wow 8 hours that´s enough !
in how is the signal quality by comparison
with an SIRF III or another GPS-Mouse ?
Cu Ulti and THX !

In my opinion not as good as a stand alone GPS. I own a SiRF XTrac GPS (royaltek rbt1000) and it is far superior. P3600 fix times are in the multiple minutes sometimes/mostly, and reception is worse. My stand alone GPS almost allways recieved 6 to 10 satellites, my P3600 usually 2 to 4, sometimes only 1, hardly ever more then 5
I just tested my built in GPS in downtown area, lots of buildings. It cannot always hold the signal and drops sometimes. The standalone has never dropped a signal for me yet.
Hi,
that makes me sad !
Is there a possibility to improve the quality with a new ROM ?
I don´t think so but perhaps somebody knows more than I !

Well I mean if you're not in downtown core area it works fine. Still takes a bit longer to get a fix than my BT unit but other than that it works fine.

I did a comparison between the trinity internal GPS and a SiRFIII GPSr.
http://forum.xda-developers.com/showthread.php?p=1123327&posted=1#post1123327
Have a look for yourself.
I believe Kaiser rely on the Qualcomm chip for GPS. How is the performance. People say good thing about the SIRF III chip. How is the Kaiser GPS compare to the SIRF III? Anyone know?
welll in most cases built in gps arnt as reliable as the actuall thing... they are off sometimes
I guess it may depend on what you want/need to do with GPS.
If I turn it on and run Google Maps, it shows me right in the middle of my house, and that's where I am. If I move from one end of my house to another, I again appear in the right place.
To use GPS do we require to have gprs or 3g data activated.
Or is like integrated FM Radion which doesnt require data connection.
No -- there is a GPS receiver built into the unit that sends NMEA 0183 data over a serial port. You'll probably need map software; any software that works with WM6 and a Bluetooth GPS should do the job (e.g. TomTom 6).
I use Googlemaps and TOMTOM 6 with no problem.
I need to mention that I am a current HTC Trinity owner, and if IF if IF if IF the Kaiser has the same A-GPS chip found in the trinity, then this is what we should expect (from my experience with the Trinity)
1- Initial fix time can take long (sometimes it takes 2 minutes, sometimes 5 minutes, sometimes 10 minutes, and sometimes IT NEVER gets a fix and no GPS singal can be found)
2- Once the GPS get a fix, then it works perfectly and flawlessly.
So I only hope that the Kaiser will solve the initial fix problem.
Has it now "normal" GPS or the mobile Version AGPS
I guess you could upgrade your radio to 1.40+ and try again. They said there's a big improvement to GPS fix.
Talking about TTFF, if you are moving, or inside a building, I think it will take longer than usual to get a fix. I live in a really urban area, but once I stand still in an open area, I usually got fix in 2-3 minutes, without exception.
Someone did a test in the Trinity forum - the accuracy of the qualcomm chip is even better than that of the sirf-iii.
However, a major problem though is the lack of a software assisted gps problem that can improve the ttff time. (Though qualcomm said there's one, but until now it's still vapourware.)

I also have the Trinity and can back up the above comments. I have a Sirf III device as well and apart from the Time To First Fix being quicker there is no noticeable difference between the two - both very accurate and don't lose their fixes.

Really interesting. The author of this article think that the Kaiser will have a Sirf-III. Now I think for the first time, we got a device with 2 GPS, a dedicated Sirf-III GPS chip together with a Qualcom integrated GPS.
I would imagine it will greatly increase the accuracy as well as the TTFF
Oh, wait, HTC might disable the Qualcom GPS, and just use the Sirf-III. See what they did to Hermes
Does anyone know how to start the gPS on the Kaiser - I bought one ...but don`t know how to start !
I find the GPS signal of Kaiser to be a bit weak, when inside the office, I don't get the signal anymore. Is there any tweak to strengthen the signal?
Also, What is the purpose of the baud rate?
Of course the signal is weak inside a room, because the room might block it.
And the signal strength may vary. I found it is not consistant (obvious).
I was driving in Belgium area (country road) with only 1 signal bar on TomTom 6 and it worked fine
Hi
GPS is designed to be used when the device has a clear view to the sky, if you get anything inside a room that's a big bonus!

? Why do you need a GPS signal in house? Do you need navigating from your room to the kitchen?
Sorry wanted to be funny, but it's like PhilipL says GPS was made to work best in a clear view of the sky
Very funny ... Thanks bro, you enlighten my day (slecht weer vandaag).

Does anyone know what phones have best GPS signal? I cannot find any group that tests phones in this regard. I found that ZTE Skate is really good.
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.

thank You for you reply.
Will try tommorow morning.

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 my name is Mike. I am currently having a problem with my AT&T Tilt (8925)s GPS unit. I see the orange light at the top flashing but the phone is not recieving signal at all. I heard if you use HTC GPS Tool it will tell you if it works. I am using it right now and I am noticing all these messages rolling over the screen when I select COM4 4800:
$GPVTG,,T,,M,M,,K*4E
$GPGSV,1,1,00*79
$GPGGA,,,,,,0,,,,,,,,*66
$GPRMC,,V,,,,,,,,,,N*53
$GPGSA,A,1,,,,,,,,,,,,,,,,*32
repeated over and over again.
When I click the satellite tab nothing is found.
Also I am not sure if it matters that my keyboard is the old version and it claims to be a 8925 when it looks different in pictures online.
If anyone can help fix this problem I will pay $3 via paypal (IF ALLOWED BY MODS AND ADMINISTRATOR, OTHERWISE FORGET IT)
I found this on a website but I still dont understand why its doing that.
$GPGSV,1,1,00*79 = 0 Satellite Vechicles in view
$GPGGA,,,,,,0,,,,,,,,*66 = No GPS Fix data available
$GPRMC,,V,,,,,,,,,,N*53 = V in field 2 means navigation receiver warning (invalid position)
$GPGSA,A,1,,,,,,,,,,,,,,,,*32 ==> Automatic mode (3D/2D) & Fix not available
$GPVTG,,T,,M,,N,,K*4E = NO GPS data available
EDIT: I tried the GPS on Android 2.1 on the phone and still no connection at all.
I dont understand this.
Please help me!
Thanks,
Mike
I take it you have tried a soft and hard reset?
Are you outside when it is looking for Satellites? It can also take some time to get an initial lock on. Perhaps if you switch off the auto-off/powersaving part of the phone and go outside, set it on a wall and wait...and wait....and wait... and hopefully it will get a lock.
Good luck I recall years ago with a Garmin GPS that was Serial and not Parallel receiver it would take aaaaaaaages to get a lock on ie, up to 45 minutes! Usually after it was OK but even so!
Is this a factory rom?
Not Sure of your location... However when I experienced problems in the STATES it was usually the Radio I need to change... Plus having [QuickGPS] installed to help moved the GPS initialization along [Finding a satellite lock] For me about 2-5 Min on average, depending on location. Also not sure what you use for Navigation but I use TomTom and it's been problem free....
Good luck

Good advice.
Got one questions for you guys, are you using additional antennas or is there's a build-in one? My kaiser really sucks about gps, it hardly ever locks gps even outdoors. But got a solution: Get a cooper wire which fits into GPS antenna socket, cut about 5-5.5cm of it and stick it into the socket you can bend it so it won't disturb. Maybe you can stick it under the rear cover so it won't be visible.
With this short cooper wire i've got a steady gps lock even indoors.
Sorry for my bad english
