Here are my results from testing the different GPSmodes in the registry with and without AGPS:
HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS
hotstart
outdoor
----------with AGPS----------without AGPS
mode1----------no gps-----13 sec to fix
mode2----------13----------13 sec to fix
mode3----------13----------13 sec to fix
hotstart
indoor with window
----------with AGPS----------without AGPS
mode1----------no gps-----10 sec to fix
mode2----------20----------14 sec to fix
mode3----------24----------30 sec to fix
What abour your results?

as per subject what is the reasonable time for gps fix? can installed applications effect gps fix? what about clouds? could it be hard to get fix in cloudy whether?
Don't know whats normal but sitting in my house with TT I get 3-4 bars in about 5 seconds once I open TT. This is on the kaiser not the fugly

goto www.gpspassion.com and you'll find a wealth of gps info. Reasonable time with quick gps is about 5-20 seconds with a good signal (outside) on the kaiser. Clouds can affect things but I've never seen it hamper anything.
I wonder if there is a difference in aquiring signal between the Kaiser and tilt? I have not seen much issue on the kaiser but there are alot on the tilt on several boards?

my kaiser takes very long at the moment
It can take up to a minute or so if you haven't used it in a while. Sometimes it pretty quick (like <15 seconds, esp when it has been used in past hour or so).
I used the GPS today for a road trip. . . fired up QuickGPS and then launched my mapping software. It only took about 10 seconds for the software to "find" the onboard GPS -- and this was the first time I had used it in the 24 hours I've had it.
You need to use QuickGPS first.
I tried my Tilt with iGuidance and got very disappointed. The GPS has an issue following my position. It updates the position on average every 30 sec and by the next update I can really get off the quided track.
Other people tell me that something is wrong, as the arrow on the screen should be following me smoothly in real time, not jumping city blocks. The only configurable setting for the GPS is baude rate, but I tried all values and still the same. What could be the problem?

are you in the city with a bunch of tall buildings??
also d/l htc gps and see how many sats your locked on.
I was mostly in the city, but no tall buildings. The GPS can lock me really good and fast, the reception is good, it finds like 8 sattelites. The only problem is it does not stay continuously locked on position, but lockes every 30 sec or so..
I installed the logging tool and will give it a try. Thanks!
What ROM and Radio do you use? stock?
I am using The NoThrills ROM (CE OS 5.2.19170 (Build 19170.1.0.0)), which comes with R 1.58.26.20.
Just tried the HTC GPS tool - not sure what exactly to look for, but it keeps logging very fast, the lines in the logger change at a rate e few per seccond, it always showed 7-8 satellites locked and yet did not update my position in real time, but probably every 30 sec.

If you are using Iguidance 4 then this is a know issues with the GPS chip in the tilt. It will not work right, the only work around is to use a separate bluetooth GPS reciever and not the internal gps. The other way is to use a different GPS software as Iguidannce 4 is the only one that I'm aware of that has this issue....
Yes, I am using iGuidance 4. Where did you see about the issue it has with the Tilt? Can you post some link? I can see only positive feedback. Would be good to know that it is a software issue and not my Tilt.....
Hi, I use miomap. My GPS is not smooth too. I don't need to wait 30 seconds to update the position, but it may need 3 to 4 seconds to update the position. It is not as smooth as tomtom.
Check out a program called GPS Gate. This issue typically has to do with WM6.1 and iGuidance 4.0 not playing well together on the Tilt. GPS Gate reports the GPS feed into something that iGuidance 4.0 can be happy with. Here's another thread for more details...

i read lots of thing about gps error in diamond [cant find signal ].
but what is the final word and final solution for gps error ?
Running on the latest europe english rom and i have a bit of lag (1-2 seconds) in igo. The next version should fix it for good, but by my standards a 2 second lag is critical only when you're going waaaay too fast . My iGo finds the satellites in under 10 seconds (or a minute if i "clear" the gps data - also known as a cold start).
Yestarday i used the gps in a canyon 10 meters wide and 70-80 meters deep. Didn't expect it to work but it did...
I9000XXJPM. Some say GPS is fixed and its perfect now. Is that true ???? Please share your experience.
Galaxy S I9000XXJPM still not the best GPS

Hi, I've tried I9000XXJPM. That version still has some GPS limitations. The version seems better than 1 or 2 months ago (the position is more exact) but it makes long time to converge. It seems Samsung has added a kind of position smoothing/averaging (~30 sec time constant).
So, I would conclude that I9000 is still okay for GPS driving but not the best one (I drive often with it; GPS Navigation works fine but finds the wrong street 5% of the time in average, mostly in cities or crossroads). After some benchmark with other Samsung and HTC phones, I can say that I9000 is definitely not the best one.
Some more detailed info about my benchmark:
1- I camp to a certain location and observe that my Galaxy S Google Maps app finds my location with +/- 5m within ~20-30 sec (with the help of the GSM triangulation so-called A-GPS).
2- I move 20 meters away (it takes 10 sec to walk).
3- Every 5 seconds I see the blue arrow slowly moving in the direction I am going to, with a delay of ~10-15 seconds.
4- After 60 seconds my Galaxy S has found my new location with +/- 5 m precision.
5- When I move back to the original position, the same delay/smoothing towards the original position is observed; it takes again 60 seconds.
My two benchmark phones (HTC, other Samsung) don't show that smoothing effect. Every 5 seconds (10 seconds sometimes) my current position is updated correctly (still with +/- 5 m precision).
I'm starting to believe that the problem is a hardware design problem (maybe noisy GPS antenna, influenced by other RF signals, maybe GSM antenna), and Samsung implemented a kind of smoothing/averaging effect in order to compensate the imprecision and let the applications point to more exact location, at the cost of long time to converge.
What's the opinion of GPS experts around?
Does anyone also notice that the S10 drops the GPS fix for several seconds when passing a loop on the highway (german Autobahn has many of them)?
When I'm in the middle of the loop the fix drops and google maps navigation freezes and then jumps around in the map for about a minute. This is a serious problem when you need to know the path in an unknown region. I tracked this with several gps tools from playstore, they all show that the fix drops from minimum 10 to 25 satellites to 0 immediatly.
I already tried to delete A-GPS data and refresh them and recalibrated the compass, but that didnt help.
Any solution or workaround?
I think you are going way to fast on the Autobahn. The gps cant catch up with your car
Yes, you need to slow down. GPS satellites travel at approximately 14,000 km/hr so you're out running them. ? I'm not sure there is a fix because I imagine those coils have a magnetic field. Maybe try making a little tinfoil hat for the phone which would probably also block the GPS.
