Hi,
today I've checked how the altitude is calculated by the Kaiser. Here is a comparison with an external SirfIII GPSr, which correlates well with real altitude above sea level.
The Kaiser shows approx. 50m too much, even with low vdop.

Do you experience the same? Is there a possibility to put an automatic correction somewhere in the registry or use another driver?
well according to the sirf III readout you can jump 100ft. so i wouldnt take that as a very good comparison
If you want to know altitude, buy an altimeter. GPS is just not designed to do it accuratly.
Hi,
thanks for commenting. Of course I know about the drawbacks of GPS for altitude measurements, but a constant offset is strange (In the graph shown, I moved and was often in areas with bad reception). Maybe the chip does not take into account the deviation from perfect ball structure of the earth surface. Or there is a possibility to calibrate, which was not done. But if you experience a different behavior, there could be a chance to correct it.
If I recall the SIRF III has WAAS/EGNOS correction capabilities and the the Kaiser does not. If so would that make a difference.
Can you turn the WAAS/EGNOS off on your external unit to see how the altitude compares without correction?
My Kaiser's GPS seems to have an altitude offset of about 35-40 metres. I've tested this when I was at the beach, around 1 metre above sea level, and the Kaiser was showing 35+ metres. As others have said, the problem seems to be that conventional GPS systems are not designed for accurate altitude measurement.
Having said that, it appears that the altitude in my Kaiser is reported with a seemingly constant positive offset of 35-40 metres, so it would be convenient to be able to adjust the GPS module/driver to automatically subtract 35 metres from the reading. But again, the offset may change if the GPS is operated in another place (say, a different country), due to the non-perfect shape of the earth. So the offset adjustment may work in one place but not everywhere.
The altitude in the Kaiser's GPS is good for observing variations, like rising or falling altitude, but the actual values don't seem to be very accurate. If you want accuracy, a dedicated altimeter is the best choice.
DrXDA
Some programs like GPS Tuner have a place where you can specify a constant offset to add.
Answering the post from PsyOpWarlord: My BT SirfIII is operating without WAAS/Egnos.
Normally, it is a good way to stay at the same place and average over 5mins to get a good accuracy for both horizontal and vertical position...
Forgive my ignorance but what application are you using that gives you altitude?
Living in Colorado that would be an interesting piece of information, even if it is offset by 30m.
Thanks
I would recommend a software called glopus. It has extremely many possibilities. It's in german, but most of the features are controlled via icons.
For grins I broke out my old handheld GPS unit (Fortuna GPSmart) to see the difference I get between it and my Tilt.
I averaged 5m-10m difference between the two with the Tilt being the lower reading and the Fortuna being the upper.
If I have free time at work (which seems increasingly less nowadays) I'll see if I can get my hands on a military grade GPS unit at the base I work and compare the readings.

There's a free one called VisualGPSce that will give altitude... and it's in English.
Well, that is how a GPS works ..
The altitude that a GPS displays, is the altitude above/below the WGS84 ellipsoide. That is a estimation of the form of the earth, but since it is an estimation only; it is not exact.
Some places it will be above the 'real' altitude, and on other places it will be below.
Some GPS chipsets (like the SirfIII) have a builtin correction, making the altitude fit better with the earth-altitude; but that correction is not always activated.

I have been dreaming about the HTC Shift so much I could not wait. I bought this HP Tx1001Au tablet until I can get my hands on one.

The touch screen is perfect. It works the same way as a ppc but requires a firmer touch to activate. The touch screen software (I think provide by HP not vista) is done to perfection. In the past i have found tablets unusable because of the rigmarole of entering text on a regular basis. This baby knows exactly what I want to do before I do. The sip can be a keyboard or word recognition. The word recognition is light years ahead of what we get on windows mobile devices. I can write naturally in running writing at my speed in a messy way and it almost always gets it correct. When it gets something wrong it can be edited on the fly without having to go back and re-write the text.
The processor (AMD Turion 64 bit x 2 core at 2 Ghz ) is capable of matching all my needs. The ram is a low 1Gb but I will buy 2Gb in the next few weeks.
The finger print scanner makes password storage and use convenient (if you trust Verisign).
The wifi is also done well. It connects to my network in around 2-3 seconds, a lot faster than my other machines running XP.
The one big downer is the overhead that Vista ladens the system with. This machine operates almost exactly the same as my last computer and that was only 1.2 Ghz. The extra 800Mhz is swallowed up by vista and all its paranoid DRM obsession. The aero desktop also slows it down considerably as does the user account control. If I turn off aero and UAC the thing noticeably jumps in speed and becomes generally more responsive in every aspect from tap recognition to opening files.
Vista has also crippled many of my favorite programs. PeerGardian2 the best privacy tool around does not work at all in vista, leaving windows free to phone home any time I connect to the internet. UAC stops programs such as WinRar from integrating into the shell correctly, another reason to turn off UAC.
Definitely worth buying and compares well with other similarly priced laptops.
Please send it to me.
one cool thing is that vista hooks up with my hermes bluetooth so seamlessly.
I just had to push a few buttons then type *99# and I was online. My phone has a faster connection than my home ISP. I am posting this using my 3 connection and writing in cursive using word recognition. It has not got one word wrong so far.
The only negative using the phone as a modern is that if I let the power go off it crashes after about 5 minutes and requires a reset. That kind of sucks because it means the screen chews through power faster even if the back light is off
If this is the future of mobile devices then PPC will be dead within a few years. kind of sad.
Well I am kind of drooling here, stuck with my poor P4 2.8 / 512MB.
Then again I am don't have to go anywhere near vista. (In fact yesterday I installed Ubuntu and now waiting to see if it really can replace the XP, probably not since I need eVC 4 and VS 6)
Still great gadget! Have fun with it and who knows - maybe HP will take a hint from Dell and drop Vista as well.
If you like this thingy, you're not going to like the Shift. It's stuck with a rather lame VIA processor, which your Turion DC outperforms by tens of times. The only thing you'll love the Shift for is that it'll have a better battery life compared, and the phone stuff is built-in.
(And worse still is that the Shift "rocks" Vista. If XP can only run *decent* on a VIA C7M 1.0, I can only imagine what Vista will do to it.)
OMG these are so hot on the market right now!
I thought I'd do a signal comparison with the new tilt. I used TomTom gps viewer for ease of use.
Here are my results.
Patio area:Fairly covered, narrow view to N and E 45* at best, mostly 80*ish

I used the sunroof because I typically put the SIRFIII receiver in the sunroof slider for best signal, this is obviously not possible with the tilt so I also tested at the console...

Notice the Tilt at sunroof is nearly = to SIRFIII at console...
Now I tried one to test the SIRFIII's capabilities.
Inside garage with door closed on bottom floor of 3 story building on the console....
I couldn't believe it still got a fix on there, I'm amazed
And of course
Tilt in garage on console...NO FIX (duh)
If anyone else has results/input please do add.
I am inside the building, and still get result!

Same here. =/
me too. I get no fix inside my 2 story house with no trees around. I lose fix even inside a train that is travelling through a wide open area.
2 stories above me.
For me it basically works every where I have tried. Locks under 5 seconds. Used to have the Ipaq 6945 and took almost a minute to lock and never got a lock inside buildings. I do know know how well this compares to external ones since I never got the chance to try any. Overall very satisfied.
I have never got a fix inside a room and I think this is quite obvious.
And basically I dont really care, why do I need to use GPS inside a room?
The thing that really important for me:
- How is it perform? Do you get signal lost quite often?
No, I dont. I have the same experience when using my old Magician+BT-338 Sirf III external GPS.
In some rural area in Belgium I noticed the Kaiser GPS has only 1 bar of signal, and it worked fine.
- How fast is it to get satellite fix after exiting a tunnel?
Again, same experience with my old SirfIII GPS.
- How fast is it to get the first satellite fix after turned on?
Very fast, between 5 - 30 seconds The same experience with my old SirfIII GPS.
Well, at least, thats my own experience.
For sure, SirfIII GPS could be more powerful than the NMEA of Kaiser, but the NMEA is powerful enough
At first I was quite skeptical about this NMEA vs SirfIII, but not anymore.
Next week, another test ... 450 km driving to Germany

I find my Kaiser VERY slow to get a lock. Even outside with no obstructions. More than two or three minutes in most cases.
I'm comparing to a Garmin Nuvi 660...
Only software I have tried is the GPS photo and Google Maps.
The Kaiser GPS is A-GPS, meaning it can use mobile phone signals to aid a fix.
Personally, going from a bluetooth sirfIII to the kaiser GPS, I don't notice a difference in accuracy in day-to-day usage.
Fix time, however, with the Kaiser, is much, much quicker. 5 seconds max usually.

Have you updated the GPS quickfix software? This downloads the satellite positions in advance so that it does not have to download them from the satellites, which is low bandwidth and subject to interference. Even if you could see every satellite, you won't get a "lock" until it knows where the satellites are and can do the triangulation.
I have always been able to get a fix inside my living room. The only place (inside) where I have not been able to get a fix is at my workplace, but, then again, I don't get cellphone signal at workplace either.
It seems we either had a poor experience with it, or a great one. I'm using the ATT ROM.
AGPS (Assisted GPS) is disabled in AT&T's ROM. Can someone with the HTC ROM check HKLM\Software\HTC\SUPL AGPS\EnableAGPS?
On the AT&T ROM EnableAGPS is disabled, or set to 0 and the GPSMode is 2. What are these values on the HTC ROM?

AGPS will help get your location using the cell network. I will enable it and see if it help getting GPS locks while indoors.

Did it help at all ? Very intresting
It did not help at all. The server configured in the registry is for Orange in France. Unless we find one server that works for us in the US, I don't think we can use this feature.

Hi.
I know this might already be confirmed but I did a simple logging on com4 and found that the gps i really there. Will go out later today and test it again but this time outside. I attach the logging to.
One more thing, it´s kinda strange the gps is always on, atleast htc could disable the gps for real if they´r not gonna use it. The battery time would increase alot.
GPS is enabled, how more i read about it it has to do with something like no antenna is connected. When i use the GPS test tool it finds a GPS on com4 and have one sat in screen.
lol
to cold here to go outside, put mine by the window the other day and got one sat with GPS test.

Thanks. I only get one satellite as well.
Im very happy!! 1 sat. is better than no sat.
hope we can get GPS running for real.. soon
As jockyw2001 also wrote: We need pics of the inside of S730, both pre-production (with antenna) and current production model/or service manuals of Kaiser and s730. Then we will be able to see how the antenna looks like and where is it connected.
Idea!!
Is it possible to make (by HTC) the hardware switch on s730 board, which is disconnecting the antenna?
Then, the antenna could exist and the new ROM could enable this feature in future.

Is there anyone here in the forum that actually has GPS working and getting a few sat signals etc.
it will be intresting to see if there is any difrerences in there registry. If someone has it working can they post the reg. info so we can compare.

GPS is not always on. It has some power saving timeout and 'wakes up' when communication port is openned and GPS data are read.
On the COM4 is not directly GPS, but GPS intermediate driver (someone knows it from PPCs), that allows more application can read from one COM port.
oh
something else i thought of is there a working driver for the gps on the phone or not? Im not really sure if it needs one.
Also i found a pdf of the msm7200 chipset. not that much to look at but you can see the gps etc and how its wired and i presume an antena at the end.
Follow the link http://www.3gchipsets.co.kr/download_library/pdf/msm7200_chipset.pdf

yes it was a preproduction model. In the official models its not working. We need to find out what is difference between both models
I am still new to the smartphone world so I cannot be of too much help, but this is what i've seen thusfar;
With GPS Test I have gotten sats on com 2,4 and 7, every satellite I pick up is at 0 on the little map locator screen. The GPS tool never gets past GPS starting up, stays fixed at 1D and no other info gets downloaded.
My testing has been in very cloudy weather over the past few days here in Texas, today though its nice and clear so I hope to get more done. I played a little with the baud rate but nothing came of it. When I did pick up a sat it was gone in 10 - 20 seconds. I did at one point pick up two at once, both in the same direction. Overall I have seen 6 different satellites, only 2 at once, and all from the same location. Could be thats the only open direction I had for visibility at the time.
I do remember reading somewhere that the GPS chip had a small antenna actually built onto it. Hopefully we can get it working soon.

This is one place, I cannot find the other place, it was their blog or one of those other sights that has a blog in playing with the pre production unit they talked about its processor and GPS... I'll try to dig it up.
Getting really annoying having the tool stay in "GPS starting up" mode none stop. Need to find the HTC version that the pre prod. phones were using or figure out how they nerf'd it.

Hello! I used my Diamond inflight (from cockpit B-737) using NAVGPSpro 4.5 its didnt work , but on the ground i can use all my GPS programms. I have tried to switch ON/OFF phone, soft reset, started all my programms but.....
Could someone help me please? Why Diamond dosent work inflight?
P.S. Glofiish X900 working well. And sorry for my english, i am from Russia
I am no expert, but are you maybe travelling too fast for the Diamond GPS to lock on?
You need to have an extra satellite fix for aviation software to give you your altitude.
But X900 working excellent. What are restriction to use Diamond GPS? I didnt find its. NAVGPSpro is special programm for aviation. And one more: sometimes i have had successful attempts.

i'm gonna go with this answer, it sounds cooler.
I've tried Diamond inFlight using IGO8, TOMTOM7 also OZIExplorer and it worked fine. It takes some time to find satelites for the first time.
Possible that the heating elements in the windows are limiting the GPS reception? Do your 737s have the eyebrow windows?

I am agree with you about first time but further attempts after several time unsuccessful. I can observe just 1 or 2 satellites not more
What version of radio do you have?

1.May be but X900 working well.
2. No they are closed by panels
i was able to get the GPS Cycle Computer to work, but with no altitude measurement. top speed = 503 mph
tomtom 7 would not work. waited several minutes, no sat lock.
isnt this illegal??
radio communication is supposed to fk up the flight instruments n stuff.
if that was true then every osama fu*kstick wanna be would be bringing down planes just by turning on the gps. the fact is back in the 70's and 80's there was a problem with interference but the technology is better now so its not really a problem any more.
GPS is passive-recieve-only, its based on a bunch of satellites sending accurate timestamps to you for triangulation. So no, it won't **** up nav systems any more than listening to the radio.

On the next picture, the altitude profile show some gap (i put some pink in the image): 6 500m to 3 500m in one second.
Those gap appear also on the map : the step on the red trace.
I've got no explaination for those gaps:
My flight was at 4 000m or my descend is stronger than the altitude profile show.
I'm not sure it is safe to trust the altitude given by the GPS in a plane.

That's the common misconception.
It is illegal for passengers to leave on radio communication devices during a flight. However in most cases its harmless.
I remember reading that only a few frequencies which do interfere with aviation communication. and these frequencies are NOT currently being used by ANY mobile phone networks.
Haha, i do love it though when i play with my Diamond on the airplane while having it on flight mode, and people around me are like staring.... and thinking OMFG THAT DUDE IS A TERRORIST HE HAS HIS PHONE ON!!!!!!! I even had a old couple remind me that i have to turn off my phone.... haha very amusing.

Are those screenshots from NAVGPSpro?
I use Memory Map with the CAA 500mil chart, and it works fine from the small cockpit of my Jabiru.
I had RC33,
and upgraded (imo) to Cyanogen.
Im trying to pair with my tomtom G630, but no luck.
the phone sees the tomtom, shows as "paired but not connected"
the tomtom doesent even detect the phone though, despite the phone bluetooth being set to discoverable.
It worked fine before.
any ideas?
From what I know, I'm pretty sure Cyanogen mod fully supports all the BT features, maybe you got a bad flash. Check the md5sum and if its not right delete the file off your computer and redownload and wipe, wipe ext2, repair ext2 and wipe then flash.
man, i hope that's not it, everything else works absolutely perfect, tethering works beautifully.
Im more inclined to blame the damn tomtom than the G1 LOL
haha
Yeah, I use an app called CoPilot but its expensive so I recommend AndNav2
Its not that bad =]
I already bought the tom, and have updated the maps already once, so ive sunk about $400 into it, its not getting replaced any time soon.
Im racking my brain, but there just really isnt anywhere to go on this.
If i set the phone to be discoverable and run a scan with my laptop, boom its found, almost instantly.. So the phone IS discoverable, just not by the tomtom.
Ok, so now things have swerved far into the retarded lane.
My Macbook can detect the G1 just fine.
If I set the macbook to be discoverable, the tomtom will find it just fine.
so the G1 is boradcasting and can be discovered, and the tomtom is trying to detect and is detecting other discoverable devices..
but not the G1.

AH HA!!!
got it!
the trick (if you can call it that) was to do "connect to bluetooth device" not the scan for phone option.
WELL CRAP
I still cannot use tomtom traffic, says the G1 is not capable of wireless data or something to that effect.
poop.
aww haha, hmm maybe TomTom will update or a dev will code something to help out.
not sure, I don't have a car nor a tomtom lol
Please don't take this as me flaming, but did you say "Maybe TomTom will update their code"? No way! They are lazy when it comes to that, even when you have purchased their top of the line products, they just don't care. It is take it or leave it when it comes to their stuff. I had more luck working with Parrot, Cardo, and a few other companies who actually wanted to help make their products work, or at least listened to work-around ideas to help implement them.
I am stuck with a TomTom Rider 2nd edition for my 2 wheeled ride and it hates my G1 phone, all TomTom says is to deal with it or to get an older phone from their list of phones that are known to work. I even offered to pay for a new map upgrade and they said it was not enough. BTW, I had 2 GO910 models and they both took a crap in the first week. I had to fight with Circuit City to rectify the problem (even with the extended warranty). I ended up getting my money back since TomTom blamed me for having a car with a tight suspension and was not willing to fix the unit. This was on a Chrysler 300M with the touring package. When they told me that line I laughed so hard that I cried! Next time I'll get a GPS from a different company or just try the TeleNav program on the G1. I wish Google Maps read out turn by turn directions and stuff.
If you know linux, you might want to just try to hack into the GPS and work that puppy till it begs to connect to your phone.
