How fast do you get a GPS fix?

Using Tomtom navigator, it always takes about 2 minutes to get a satellite fix (with quick GPS updated) on my Artemis/MDA Compact III . On occassion it's even longer, but in general, 2 minutes. Never less time, apart from closing navigator down and starting it up again when it'll then get a fix pretty fast.
Is the GPS receiver on the Diamond, specifically, the T Mobile MDA Compact IV any faster? I believe there is no quick gps feature on it? Also, I read somewhere on this site that someone with navigator 6.02 got a fix in seconds. I have navigator 6 and now I've bought nav 7. I'm not sure if my navigator 6 is 6.02, probably not. I'll have to check.

Its probably v6.75
Im running v7.45 and it takes me 2 minutes (sometimes less sometimes more) to get a cold gps fix. I find alot of buildings are my biggest enemy when locking onto a satellite, but thats old news.
I am not running Quick GPS but I was planning on trying it out.. the reviews are pretty good on an htc.
Running a diamond here too.

Using a diamond with the .07 radio and Quick GPS I get a fix in about 20 seconds

im using the 05 radio and quick GPS, i get a fix in 30 secs

For me, it's definitely a TT7 issue. When I use any other of my GPS apps, I get a fix in sub 30 seconds in all but he worst of signal/sky obscurity situations. In TT7 it usually takes a minute or more... the difference is so pronounced that if I need TT quickly, I run up Fugawi to get a fix in a matter of seconds, and then I run up TT.
So perhaps TT has some kind of higher signal quality threshold or something??... or maybe it's just the programming in its startup routine that's slow.

Diamond SwiftBlade V6.5 radio 05, sorry dont use TT, use IGO8 takes about 5-10 seconds, memory map OS takes about 5 seconds, RunGPS is almost instant warm. Cold add about 10 seconds on each.

.05 radio, fix in about 20-30secs

Same here in any GPS app including TomTom 7, even indoors I get a fix in under 30secs and connect to around 6-8 sats even if the GPS has not been used in 24hrs.

Im using TT7 and .07 radio/quickGps and I get a cold fix in 20-30sec, warmfix we are talking about few seconds

I had few probs with GPS, but now with Duttys V2 ROM (A-GPS is initially Off) + Radio .05 I get the fix within 10-20 seconds in any application.

Similar here 15-20 sec

less then 30sec. even for cold start

Wow, you're all getting a fix from cold in 30 seconds or less
Either I need to find the right navigator that works faster, or try another GPS app. Thing is, tomtom is the best one out there isn't it? Or maybe my artemis will never be able to get a fix faster than 2 minutes with any app.

me too abot 20 secs usig destinator 7

well quickgps doesn't work for me .. it keeps saying connection failed. with a-gps turned off, on swiftblade's rom, with igo 8, i get a fix in ... well .. not to make a fool out of myself .. 3 minutes or more ..

Had that problem too once. Had to do a hard reset to make QuickGPS work again. Now, using iGo too, I get a fix in 20-30s.

So I used to get a fix in about 2 minutes until I added the SUPL GPS to enable aGPS.
Now my TTFF is 5 seconds @ and an instant 6-8 birds. Indoors add another 10 seconds or so.
Heres the reg keys in a cab.

Hey guys, I just read up on igo8. A lot of people are saying it's the best gps software, better than tomtom. I saw a youtube video and all the maps have 3D buildings and landscapes, looks awesome. How good is igo, and does it come with speed cameras?

Hey, do you happen to know of a similar registry fix for the artemis?

Sorry I don't. Maybe ask in the same forum (not sub-forum) that the file came from.

[REQ][APP] to wake up GPS

Well, now that most of us have the Fuze GPS working, one thing that would nice is a little app/service that wakes the GPS up several times a day and attempts to get a fix.
Rather than waiting until I need to use the GPS, then turning it on and waiting for a fix, it would be great if it had at least connected sometime during the day.
Thoughts?

I think the software you are looking for is called QuickGPS. If the satellite position information does not expire your device should get a fix within under 10 seconds, so there is no need for any additional software. Just use QuickGPS so that the satellite positions are always up to date and that's it.

I think this is what you are looking for.

I think he means more so after a soft / hard reset it can sometimes take several minutes to get a full fix even after running quickGPS.
I have had it take 4 - 5 minutes even after running quickGPS. It started with one satellite and slowly grabbed 1 every 20 - 30 seconds until it had about 7 then it got full lock. Once that was done reacquiring a lock took no time at all.
I wonder if it goes to "sleep" or something as a power saving feature?

That's all well and good if you are in the same spot as you were when QuickGPS ran last. However, my problem with many GPS systems is that I don't use them often enough to maintain a sync.
What would be ideal is if GPS would stay on all the time and/or there was enough battery to keep GPS on all the time.
If you use your GPS to drive to your dentist, for instance, then drive to work without your GPS because you know the way, then need GPS to meet friends for dinner, your GPS cache is based on your dentist, not work.
What I'm asking for is an app that kicks off GPS (presumably) while you are at work. If this happens multiple times a day, it shouldn't take much battery life, but your data would always be up to date.
Alternately, is there an easy way to just run QuickGPS multiple times a day?

Moved to software.

Try Beeline GPS or Visual GPS.

Is there a program to keep GPS 'warm'

I find myself frustrated when I need the GPS fuction on my Tilt, but then it takes 2-3 minutes to locate me from a cold start. That can feel like hours when I am late and lost. When it is warm, the GPS fixes in 5-20 seconds.
It seems a program that keeps the GPS in a state of warmness (maybe starting up and getting a fix every hour or two) would really help me out. I don't have a pocket full of batteries, so leaving the GPS on all the time is not an option.
Is there something like this out there, or do I have to try to build it myself?
Thanks for any help,
Will

I've been thinking of the same thing...
2 things you can do:
1) use network location when possible. It really is better on batteries and much quicker.
2) Use a program like tasker that flips on GPS for an alotted time to get a fix every so often. I'm thinking about using a multiple profile setting that will automatically run a GPS fix when I leave my work or home networks. But it would also run once every hour when I'm away from those networks and only when I'm away.

[Q] GPS problem: fix -> lose fix -> fix -> lose fix

I'm using CM7 on my Nexus One. The issue happened twice; right now the GPS is working fine but I'd like to find what can be done to diagnose this, or if there's anyone out there who already knows a fix...
Here's what it looks like:
I turn on the GPS, open GNavigation (or Waze, or Maps). GPS gets a fix but when I start driving, it doesn't update my location. After a while, it loses the fix, the reacquires it, still doesn't update it, loses fix again, and this keeps happening as 5-minute long loops.
Here's how it looks like in the GPS Status app:
It's as if GPS gets a fix, then hangs (my coordinate are not updated in GPS Status app) without giving any errors, then turns itself off and on, gets a fix again, rinse and repeat.
What I tried:
Reset and download A-GPS state. Reset dalvik cache using recovery. Reset A-GPS state, turn off GPS, turn off phone, turn on phone (and variations of this). Didn't work...
What worked:
Finally I got sick of it and took out my real GPS device. I didn't turn off nexus' navigation (wanted to torture it a bit out of spite and frustration).
After driving for 40 minutes (and nexus finding, losing, finding ... GPS fixes as I was driving), suddenly it got a fix, and it just started working again without problems.
Anyone know what's happening here and how to fix it? Thanks so much in advance

You are not alone
Rebooting almost always fixes it for me. Unfortunately it takes several minutes.
Airplane mode also instantly fixes it, but then you lose A-GPS and all communications.

Radio updating may fix the problem.
Try flashing a latest radio image.

Latest radio
Thanks. I guess a new, functioning radio would indeed solve the problem.
However, I already have the latest radio flashed: 32.50.0032U_5.12.00.08 for the Nexus One. Earlier radios have other heavy shortcomings, so they are not a good option.

i wold know if it was good be4
cuz it was worked fine but now ive same problem
i thought this problem form rom
but now i dont know the reson
sorry 4 broken eng
thx

I am waiting for ICS and hope that will fix it.

[Q] Low accuracy in GPS.

Hi all.
I hope someone here can help me with some answers or at least help me testing.
My problem is, that when I use my phone when running, the training session isn't registered correctly. It always log my routes between 25 and 30 % shorter then they are.
I've tried using different programs like Runkeeper, Endomondo, Cardiotrainer, My Tracks, and others.
They all show the same short route log.
I've tested all the programs with my old HTC Desire, and here the error is always less then 5%
Anyone else seeing the same problem??
Maybe someone could test it on their phone the next time they're going for a run??
My guess is, that there might be some bug in the software of the phone, that makes it report to short distances between every point that it sends to te training software. (maybe something to do with the accuracy of the GPS, and how this is offset is calculated into the positiondata??)
Anybody got a good Idea where to start??

Same here, tried a couple of the running apps. Sometimes it helps to restart the phone before running. Google navigation and offline nav apps (Sygic, TomTom, Navigon) seem to show more accurate GPS data. Speed related?
