Which radio are you using?
Mine takes couple of seconds max.

I think it depends upon the radio a lot. Some radios are very quick (I am currently using NIKI XX.17 as I need quick GPS locks - now takes seconds not minutes), others are not.
When I first got my kaiser, T-mobile vario III the GPS was very quick to get a fix taking less than one minute to get the first fix after boot up and subsequently a matter of a few seconds.
Unfortunately this was about the only thing that was quick though, so I installed one of Dutty's ROMs which vastly improved the overall performance of the device for most tasks, except getting a GPS fix which all of a sudden was intolerably slow, sometimes almost impossible.
I experimented flashing various radios but nothing seemed to make much difference so I kind of gave up. The other day I upgraded again, to Dutty's latest ROM and all of a sudden my GPS performance is back to how it was when I first got the kaiser, despite the fact the radio version included in the rom is the same as the one I had before. So I'm very pleased about this, but also perplexed. I don't know what factors influence the speed of getting a GPS fix but for me Dutty's latest ROM is good so maybe you should try that.
One thing that I did notice is that getting a GPS fix was always quicker when travelling in the car not standing still.

Which is strange... Normally GPS's are quicker to fix when stationary rather than moving...
I'll be getting mine soon, so once I have it, I will test with the T-Mobile standard and - if I get it installed, being a WinMob n00b myself that is by no means certain! - with Dutty's latest...

It is strange isn't it? But I'm sure it was true in my case. For example I once walked to work with the GPS switched on as a test, I was holding it in my hand so it had a direct line to the sky at all times. When I got there about fifteen minutes later it still hadn't got a fix. The next day I drove somewhere and after about two minutes it had a fix.
As long as I'm outside (or in the car) under clear sky, I get a lock in Google Maps or Telenav in only a few seconds. Inside my apartment, but near a window, Google Maps will eventually get a lock, but it can take it 3-5 minutes to do so. In my office, which also has a window but which faces out to a courtyard surrounded by brick walls (and up 5 stories above my floor), I just cannot seem to get a fix at all.
Outside with clear sky above though, moving or stable, it is very quick - never more then 10s and usually far less.
What kind of buildings and other obstructions were around you? In order to get enough fixes to pinpoint your location it will often have to see sats out to some pretty steep angles. One guy we met who does commercial GPS systems showed us where the birds were from out on a beach. The 4th one was only something like 20 degrees above the horizon out over the ocean.

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 just wanted to say that the GPS in the Diamond is one of the better I have ever used.
I am now running the .08 radio ROM and the GPS Fix is under 20 sec.
But, thats not all. Now I also got FULL GPS reception in my VW Multivan.
Some of you maybe think.. "ehhhh.. whats so amazing ´bout that??"
Well, my car got this special windscreen that F**k up the reception of GPS´s and mobile phones.
I think that I have tried 4-5 different GPS devices (pocket pc´s, tomtom´s, garmin etc)
and I had to add an external antenna to get a good reception.
But I tried my diamond yesterday, and I got FULL reception with the diamond in the same position on my dash. (in under 20 secs of course =) )
So.. GO HTC.. GO GO GO!! =)
lol! it seems that you and me have some special diamond. using iGO8 and driving a Peugeot 207S with the same type of windscreen. even my athena has a hard time with finding satellites....the diamond is "on" in under 1 minute!
i posted a link to yr post at the longest and saddest GPS thread:

time management at his best!
I'm still impressed with mine when I manage to get a signal indoors with no windows around
I love my GPS too. We need more posts like this. It's so easy to critisize a few weaknesses, but this is a masterpiece of a telephone with such amazing features despite such a small size.
confirmation
I can only confirm that the GPS in Diamond ist the best one I ever had.
Total connection in less than 20 Seconds (sometimes even in only 10 Secs).
I think, there is no other device with such abilities.
Due to my job, I have to use it more than 10 times a day for various address and I can only say, it works really very reliable. I use íGO 8.
To get TMC-Information I use additionally at the same time also an another TMC-GPS-Device (GNS 5840). They work great together. GNS-5840 ist very cheap to buy it as used and delivers ony the TMC-Signals.
All in all a wonderfull device without any problems. Simly amazing.
Yeh, same for me too... very rare mine takes more than 30 seconds for a fix... no matter the app I'm using, or where I am. Even indoors, I quite often manage to get a fix.
Remarkable piece of kit.
Not only me then =)
Finally I can remove that ugly external GPS antenna from my car.
right, the first time i tested GPS on my new Diamond I thought: wow, what is wrong here, this is too fast. But, no, it was working.
My previous phone was the Kaiser, and even with the old WM6.0 ROMs, it took much more time, not even to mention the WM6.1
Im seeing the same. Takes about 15-20secs to get a full lock. Seems to work all the time every time.
Similar thing here, upgraded to the .07 radio and things are much better! Lock in 15-20 seconds. I was walking down the central corridor of the hotel I was staying in at the weekend and it still managed a signal - ok so it was the top floor but still!
Now if we can have the same revalation about 3g performance
With the 1.93 rom mine stays like 30 sec to get signal... with the older rom 1.37 i think... it stayed like 10-15 seconds... but the lag was the same....
Well i have a question.
When i use TomTom or IGO the position on the screen is always about 50 meters off to where I actually am.
So since IGO & TomTom Both have the same behaviour i guess i should look at the GPS module.
My old S730 was always spot on... when i looked at the screen and saw a turn on the left, there actually was a turn to the left.
Anybody knows how this can be solved ?
My TD2 does not have this problem, perhaps there is an issue with your particular phone?
I thoght about it before and found out that it was not inaccuracy but the delay GPS chip needs to calculate your position. Do one test. Some time when you stop at a red light and you know you've waited for about 5 secs, check your position then. I believe it will be accurate then.
I noticed that some GPS's try to calculate your current position based on direction and speed you had few seconds ago. I found out about it one time when I waited at the red light in a long tunnel. Obviously there was no signal there, but when I stopped, GPS kept on showing that I was moving about 40MPH for several seconds before it finally showed lost signal message.
Some GPS's do calculate your position ahead of time and some don't.
Maybe it was because i had assisted GPS turned on...
If you do a search on AGPS LAG (ANY HTCPRODUCT WITH AGPS) then you will see enough posts that speciffically deals with this problem...
My old phone is SPOT ON with TT and my new 2 times faster phone is less accurate, and in a street with lots of turns, take a-lefts etc it's quite important to rely on the machine. And when the machine says turn left on the next corner, is that left the one i am currently at or the one 20 meters ahead from where i am now....
It should be just as with my old phone spot on
Well disabeling AGPS definitely works...
I am now about 20 meters behind all the time. This seems acceptable although I keep finding it strange that my older phone was way more accurate.....
you mean disable QuickGPS or disable AGPS in Advanced Config??
It is definitely a lag issue, not a precision issue: my TD2 internal GPS is at least as accurate as my Qstarz bluetooth GPS logger, and this one has a dedicated large antenna and good GPS chipset. TD2 sensitivity is also comparable, maybe even better inside building, and the time before locking a signal from coldstart is also comparable or better...
BUT there is a lag of maybe 30 m around 50 km/h in my car, and it is is indeed quite noticeable for driving directions...No big deal for me, as I do not rely on voice instruction but always have a quick peak at the screen (I was bitten by ambiguous instruction often enough in the past with other GPS system to have developped this quick peak habit ;-) )..but this lag is indeed anoying...
I'd like to try the TD2 using the external GPS through bluetooth, if I find time to do it this WE I will post my conclusions...

I use to have the same problem as you, so, I've tried the tweak referred in this post http://forum.xda-developers.com/showthread.php?t=514912 and it did the trick for me.
I use iGo8 and NDrive and the accuracy improved a lot, it's almost spot on, no matter what speed I'm driving.
Regards,
I was in my mates Audi TT the other day. He has the built in GPS in the dash board. I noticed there was as much lag as you see on an HTC device.
Also was in a car a few months asgo with someone who had a stand alone TomTom device and that too had lag.
Unless you're paying thousands of Dollars for millitary grade navigation equipment, i wouldn't spare the lag issue another thought.
Not long now ...
There's a bigger lag comming if the media are to be believed (and based on everything that comes from the tele, radio and newspapers these days - there're probably not - they can't even get the weather right)

"

Diamond1 paid £150 was spot on. No Lag. The speed indicator on tomtom was very accurate, not like on the diamond2 where it takes over 2 seconds to show a speed change. I am surprised that not many people have noticed the slow and inaccurate GPS performance of the D2.
I have had continuous issues with the Droid 3. One of my biggest issues is that the GPS seems completely unstable. I have tried turning on/off GPS options, etc...
Weather I try to use Google Maps or another application such as Endomondo, it cant maintain a lock. It seems to be able to locate me within 12 - 30 feet and then within a mile!!!
Using an application like Endomondo (running, cycling, etc), is completely useless. It can't track my location at all and when it does lock on, it only holds for a few seconds and then gone again.
I took the phone in to Verizon with a complaint about the GPs and screen issues (http://forum.xda-developers.com/showthread.php?t=1239980) and the rep said both were normal for this phone...
Has anyone figured out a way to resolve this problem?
I, too, have the same issue with GPS. I use SportyPal Pro, and cannot use my Droid 3 when running/walking. I can go for a 5 mile run, and SportyPal will show I had ran 6 miles. I can run north to south in a straight line, and when finished, SportyPal will show that I went east and west as much as 400-500 feet off of that straight line and because of that can add anywhere from .1 miles to .5 miles to that 1 mile run.
It is so unreliable that I will use my older decommisioned Droid2 to run with. It works perfectly with the same software.
If anybody has any suggestions, I'm all ears.

Are you using it for navigation only? Or a similar application for running/walking?
The reason I ask is because I do not notice a problem during navigation. It works great for that without any problems. Until I get to downtown Chicago. I almost expect problems there. Even with my Droid2.
i've only had issues with my gps in areas with lte. when im at college im in a city with lte support and my gps doesn't work (my friend who has an X also has issues with his gps when in areas with lte). when im home where there isnt lte support my gps works fine.
No it's not hardware mine works flawlessly and almost instantly fixes position, tho i have modded the gps.conf found in the etc folder. Details for tweaking this for your region can be found here:
http://forum.xda-developers.com/showpost.php?p=13537801&postcount=1
Many thanx to 75markus for this.
Since we don't have a recovery yet to flash a zip you will need to edit the gps.conf file manually.
Oceanic region can be found in my sig below apart of my camera mod.

The problem I was having with the GPS from Day 1 is that I would occasionally notice that it would not start up at all when openning a GPS-dependant app (such as Maps or Weatherbug, etc). Whenever that happened, I would have to restart the phone, and then the GPS would be able to initialize again... at least, for a while.
Eventually, I was digging around in the setting and found the "VZW location services" option under "Location & security settings". I unchecked that option and, ever since, I've had no problem with the GPS. It seems that th VZW-based location services were causing the problem. Of course, since then, I've rooted and frozen all of the VZW bloat, so I might be able to turn that option back on with no ill effect. Still, it was as simple enough fix.
My issue might not sound exactly the same as yours, but you could give this a try and see if it helps.

I have been experiencing the exact same problem and temporary solution (restarting) since day 1, on both my first and second droid 3's. Difference is, I've had VZW location services unchecked since around the time I first got the phones, and I am still experiencing the problem... even as recently as last night. I just double-checked the setting, and indeed, VZW location services is stil unchecked.
Once I have lock I usually have no problem continuously using GPS. Last night, I tracked a two and a half hour walk using the My Tracks app, including a 45 minute stop for dinner indoors. For the first 10 minutes, it couldnt find a signal, so I restarted. It got a lock almost instantly following the restart and never lost it after that. I had the app running for the whole excursion. As expected, it got a little confused while I was inside, but automatically picked the signal right back up when I got back outside and tracked my entire walk back home.

When you look at your walk on the map, is it true to where you actually walked? If I do that same walk on my phone, it will show me deviating off course as much as a 1/2 block and then back. I can tolerate that deviation once and maybe twice during my runs/walks. However, mine does it the majority of the time, adding bogus mileage to my walks/runs. In an hour's time, it will deviate approximately 20-30 times.

Just took a closer look at the track it recorded. I definitely do see these kinds of deviations, but they seem to only be in areas where I think it'd be reasonable to expect them. I live in a suburb, so I don't have any tall building to mess with the GPS reception, instead, I have somewhat steep hillsides. It seems I get a fair amount of deviation in the (significantly) hilly areas (it looks like I was walking down people's driveways, then across their front yards, when in reality I was just walking more or less straight down the sidewalk), but in the flat areas the line has almost no significant deviations, just some minor noise. Next time, at the risk of my fiance calling me a geek, I'll take my Droid 1 along for the trip, and see how the two records compare.

WOW... That is awful but a great example of the concern with this phone. You are actually doing much better than me. Mine is only able to triangulate down to about 20 feet and then it bounces between 20 and 300 feet!!!
I am going to call VZW today and see about a replacement phone but I doubt it will resolve the problem.
I just called VZW and once again, they said the accuracy was normal... They said none of their phones can lock on with the accuracy I described and if it has, I have been lucky. He said their phones are only accurate within 500 feet!
I explained to him that with that accuracy, it would be totally useless to use as a navigation device...
He looked through their documentation and said he has no record of other people having issues with the GPS... He also said he has no record of the blue tint when taking pictures.....
Oh well. I hope the replacement fixes it...

With that kind of change in accuracy, it seems like it isn't using the GPS as all, but just the cell towers. Is the GPS logo showing in the notification bar when that is happening? If it's there, is it blinking or solid?

My humble opinion of VZW representatives...they're all full of BS. They're going to tell you what they need to tell you to get your out of the store or off of the phone if you're not buying anything. A representative's main concern is sales. Sell him another phone, renew his contract, add a line, add a feature.
This issue may be better addressed to Motorola directly. I may make that phone call today.
I just got off the phone with Motorola tech support. Same story as VZW gives. There are NO known issues with the Droid 3. I asked about the GPS, the bluish pics the cam takes and battery life. The only thing the tech would say is the phone "needs to be evaluated"
