Just got my O2 Orbit yesterday. An awesome piece of kit. It's impossible to see just how small it is in photos somehow. Really nice and so far it's performed great. I happen to find all of the things others have complained about to be plusses (the roller and wheel, the location of the MicroSD card), so it's ideal for me, really ideal. Glad I waited for the Orbit rather than the P3300 too, even though I'd rather give my money direct to HTC! It's much nicer looking.
Anyhow, my question is that I expected GPS on/off to be on the Comm Manager screen but it isn't. Am I right in guessing that what turns the GPS on and off is whether something has COM4 open and listening? So as soon as an app closes COM4, it starts to lose location? It might be nice if there were some programmable delay post-close where it keeps monitoring in case something else opens COM4 again a few minutes later.
I think this is because keeping a fresh GPS signal is severe on the battery life.
I have a BT gps receiver which works around 20 hours on a default nokia battery. But ofcourse the Artemis is a whole pocket/phone which draws its power from a 1200mah battery.
All GPS receivers need to get a fix at the start, this takes from 30 sec. up to 2 min.
It could be when disconnecting it saves the GPS positions so on another connection it can find the satelites faster. But I don't really know how the technical part works and if this is true.
I don't know how exactly it happens programmatically, but what I know for sure is that it is turned on/off by TomTom. As long as TomTom is working, the receiver is working, too.
When I use navigation software I have to wait about 5 min or more get GPS signal (I tried 2 softwares). I thought that is radio ver problem, then I updated to radio 1.50 but still slow.
Is it normal or something wrong!! I remember when I used Bluetooth GPS takes just a few second to get it.
Thanks
It's common problem with P3600 ...
IMHO BT module is always on and fixed, that's why only few seconds...
Are you moving? i.e. already driving when you load it? it takes a lot longer like that.

Not true!
Using a P3600 and get fixed in less then 5 second for hot and less then 30 seconds for cold.
same for me...it's too slow
I've never got a fix that quick, I get a cold fix of around 5 minutes, hot, maybe a minute at best.
I've come to live with it.

I would really like to know how you can do this?
For hot ok - more or less in 10 sec, but for cold .... hm, can you tell me a secret?
I have an Orange M700 and it takes about 1-2 minutes to obtain the GPS signal but you have to go outside which is normal with all GPS signals. I don't get in my car until I have got the signal.
it might be to do with the number of satellites available to do the initial triangulation...
also, i believe the surroundings and your position are vital..i noticed it took longer in the CBD area with all the tall buildings..more than 5 mins on cold compared to my home which has shorter buildings(2 mins)..and i managed a 10 seconds fixed on a hot start while travelling at 90kmh..
anyway..we can at least comfort ourselves that it it still faster than the 6110 Nav and N95(at least the ones i've tried) =)

I don't know about secrets, but here's the setup:
GPS setup in operating system, set on COM9, baud: 115600.
Using iGo MyWay 2006 Plus with manual gps setting to the same values as in operating system.
Noroc!
I have found that the ROM version makes a lot of difference (not the radio ROM, the OS) to the TTTF. The best ROM (sorry - I can no longer remember which one) took a MAXIMUM of 2 minutes cold fix even when moving and minimum for hot fix of about 5 seconds. Try different ROM versions.
btw I always use tomtom.
However, if your journey is less then 5 minutes do you really need GPS navigation?
Anyway - flash different ROMs and see what you think.

Hi,
I dont know if this is pure fluke and this just works on my setup but i seem to have found a way to get a 5-6 second fix GPS, having said that i cannot guarentee that it will work for everyone, but you are all welcome to give it a go!
Firstly i will list my setup:
SwiftBL WWE v6.5 16Mb PP
Radio v1.00.25.07
TomTom Navigator 7.450.9028 for HTC Diamond
Process Used:
1: Load TomTom 7, and wait until you get the message "Waiting for valid GPS Signal" at the bottom left
2: Once the message appears select "Browse Map" -> "Find" and go to the page with "My Location" this will be greyed out.
3: Exit TomTom 7
4: Restart TomTom 7, once you see the message "Waiting for valid GPS Signal" it should fix
As i said previously, i dont know if this is a fluke, but i have had 100% success with this.
My Testing:
Everytime i have done this i have done this from different locations 30 - 40 minutes appart (I travel alot on the train) so my device has not been locking onto the same satelites
To ensure fairness in these tests i have powered down my device totally, started the device from cold, entered my PIN and loaded the desktop. Then launched TomTom 7
I have tryed 5 different locations in the UK over 2 Days:
Southport, Manchester, Bolton, Churchtown and Preston
I've never had a problem getting a fix with any of the diamond roms - often as quick as 5 or 6 seconds depending on where I am.
The issue that I think most people are having is the lag in providing an accurate fix.

Im jealous!
Until i started doing this i was getting 1-2 minute lock on and fix my position, but as i said this seems to speed it up alot for me.
Also, there is no lag to get an accurate fix doing the process i suggest, once there is a gps signal detected, my location is zeroed instantaniously!!
My experience is as follow (I tested a lot):
With radio 1.00.25.05 cold fix takes about 5 minutes. After that a few minutes. Once I get a fix, it's stable.
With radio 1.00.25.07 cold fix less then a minute. After that about 5 seconds. It's also stable once I get a fix.
Quality of calls is the same, so is the signal strength and battery life.
So I would recommend radio 07 for those who use navigation.
It is weird indeed. I have 05. Sometimes I get a fix in 5 secs, sometimes it takes forever.
I also found that once I get a fix the accuracy fluctuates from poor to high indeed.
Once I hit the roads, np but need to do more tests

I have had the same problem as yours with those details...
I think it maybe to do with the ROM, mainly because I have not had an issue with other roms...
Hi everyone,
I try Radio .08 and the same thing. I fix GPS in 5-10 secondes...
Some people say that with the .08, less batterie is consumed...
I don't know need to do the test...
I try Radio .08 during 4 days, and my batterie is good !
My phone is charging during 1h30 - 2h and it's full...
less consumption, but when i use GPS.... my lifetime is very short....
No lag ! but high consumption.
I can call and use 3G, during 1,5 days !
I am losing my mind with my GPS. I have had my TP2 since last August and I have never been able to find a solution to the horrible GPS quality. I have tried matching up the ports, changing the ports, different software, hard-resets, I have installed the hotfix, I have called HTC, but things are still terrible. The only thing that ever cause an improvement was manually choosing the ports and such, however the improvement was only slight.
I have used GPS on Google Maps on the iPhone under the same provider (Optus in Australia) and the moment I opened the program there was always a GPS lock, not once did I ever have to wait or get it ready, but on my TP2 using Google Maps (or any other application), sometimes I am forced to wait minutes before getting a signal, if at all. I have searched and searched for a resolution but im not finding any. I just don't understand what I paid top dollar for, I chose the TP2 over the Xperia for it's GPS capabilities, but its hardly capable. I feel as if I am out of options, i've had it for too long to get my money back; I would really appreciate your thoughts on this?
I use iGuidance2009 and have no problems, though I do update quickGPS regularly. Google Maps I dont know about as I dont use it.
This has been a problem ever since the Touch Pro. My old Kaiser never had these horrible GPS issues, Touch Pro and Touch Pro 2 do.
What I have found to work well is to toggle the phone in the Comm manager when GPS is not working correctly.
Also, if you can get AGPS to work correctly, that does wonders for GPS lock time speeds! It would take minutes before, but once AGPS is set to work correctly, I can get a lock in 10 seconds! You have to go into the registry and make sure AGPS is set to use the right data connection.
This only improves acquisition times, it does not reduce the lag which was introduced in the original Touch Pro.
Google maps is probably the worst test app for speed. I use TomTom and iGo on Juicy R5 now, default rom before, and both have no lag. Google maps lags as much as 30 seconds, Garmin and also a few free gps apps I tried lagged 10-15 secs. So this is really, really app dependent. Don't know why.
As for lock speed, agps is a must. If QuickGPS/SEASGEE isn't working then you get the same lock speeds that you would get on old, old car gps systems (up to 5 mins to get a lock).

It's just you with such serious problems, maybe your phone has problems..
AGPS is key to getting a fast lock. That's where you should be focused.
Some registry tweaks may improve your fix. It rocks for me and others owners, but not sure for every body.

No, its not. Everyone has position lag. It isn't unbearable, but it is pretty annoying. You take an exit on a highway and it takes about 3 seconds to realize you took it sometimes. What is really weird is it keeps going on one road while the arrow turns in the direction you are headed until it finally places you on the correct road. That part may be due to TomTom though, but I'm not sure.

As per my personal experience, this is due to internal GPS data filtering by WM, so tweaks recalled by woaloo (I mean reducing of WM's GPS-related data buffer sizes) can help here.
Be careful however with it as too low values will drives GPS to become "nervous" - your position will become unstable, starting to jump randomly with a radius of few hundreds meters.
Another reason of the lag is (most likely) related to the navi software one uses. I use iGO8 and there are for sure settings moderating position behavior from pretty quick (but unstable) to rather slow but noticeable more stable. I personally prefer this last one.
To the original poster, have you tried running a program like VisualGPS? If so, how much signal strength is it showing for the satellites? I see as high as 39 when indoors. I get quick and accurate locks and I am very happy with the GPS performance. I have to believe that you have a hardware problem.
As for the thread drift on the few seconds delay, yes, that is there, but not a big issue.
Personal experience with the GPS... initially could never get it to connect, basically because every time i tried i was inside behind venitian blinds..... never use GPS before so my bad.
Walked outside and it was great. About 10 secs or less to lock, the lag is only a couple of seconds, no more than 5 secs. Added the tweeks and it was improved slightly. The accuracy was within 5 meters or less (used the property boundries in google maps to verify).
Moving at high speed it was pretty good too.
Compared to other phones and iPhone borrowed from a mate there is negligable difference in the accuracy and lag.
BRETT
So the GPS performance on the Touch Pro 2 is not that much better than the Touch Pro? The receiver on the Touch Pro is extremely weak.
At my work we have a GPS re-radiator for use with the equipment that we build. Indoors using the re-radiator I can get a lock in seconds with 11 satellites (the signal is abnormally strong). Outdoors, I'm happy if I can get a lock with 7.

I did try something like that, not sure if it was VisualGPS but it showed me the strength of GPS signal and it was quite accurate with how the GPS appeared to be behaving.
I got the phone's motherboard replaced and that fixed the issue. Thank you all for the replies though, it was possibly faulty.
Have the new Energy rom on but used the GPS hotfix. Seems to have increased lock time considerably.
I'll keep an eye on it though in case the lock time increases...
Wonder if we can find an app that would imbed GPS co-ordinates in any pics we take... Got a Samsung S8300t as well & it does this though the GPS navigation software is non-existant....

One of the extra camera modes you can unlock in the TP2 is a geotagging mode that does exactly that. There's a number of ways to enable them...Rhodium Settings Tool has a switch for each of them individually (burst, sport, video share, and geotagging), or you can just run the cab below
....and, for anybody else on this thread who hasn't tried it already, I'd suggest checking out the cab fone_fanatic put together to help with GPS locks on the TP2, details HERE
Is there anyone who use defy GPS daily? Can you share which rom or any GPS tweak to make defy more accurate and responsive for navigation?
I have been testing defy GPS, it seems like its rather not accurate to pinpoint location. Accuracy show 4-9m, but often real position is off by 30-200m. For navigation, it's response time rather slow plus the inaccuracy makes it not reliable. My old windows mobile P3600 gives precise position when put beside defy while navigating.
For info, I have disable wifi in location setting. I know I have successfully download supl data. With data enabled, I can lock under 10 sec.
This inaccuracy had been a problem for CM7. I have tested stock froyo and gingerbread, and problem still there.
So, can anyone help here? Do you have the same problem, if not please share your rom version or tweak..
I've used mine a lot for gps, i just make sure to download agps data with an app called GPS test as soon as i can, then if i'm not moving too much from where i stopped gps for the last time it takes very little to lock.
I'm on CM7 and it never disappointed me in Italy, Germany, Netherlands, Belgium and France.
Any GPS fix i've tried did nothing good for me.
My defy lock fast. What bothers me is the accuracy.
Google maps shows accuracy 4-9m, but real position is off sometimes by 200m.
Sometimes it correct itself, other time, even if I waited for a few minutes, it didn't show my real position.
And I'm sure I disable Use Wireless Networks in location setting.
So how is your accuracy?
Relly good, thanks
Seriously, i've seen this mentioned quite often in the CM7 thread, but it never happened to me.
As said before, keeping agps data pretty updated to my position or close enough has always been enough for me.
Good luck in finding a solution that works for you!
GPS has been working perfectly for me under any Rom. Stock GB, CM7 and Stock Froyo.
In CM7 it locks pretty fast, always under 10 secs, after a few secs accuracy down to 3m. Works really good.
I only have GPS Status to download from time to time accurate AGPS data and that's all.
Thanks for the reply..
I have tried almost everything.
Tuning gpsconfig.xml and location.cfg, clear agps cache, restart before testing many value one by one. Tried many stock rom, take GPS files from milestone and milestone2 and the GPS still inconsistent.
Sometimes its accurate, but after turn off GPS for a few second, turn on again, its showing wrong position with accuracy shown as 4-9m, waited for some minutes, and still wrong. Sometimes its accurate for a few test, but after a few minutes, turn on GPS again, its showing wrong position again.
Tried also calibrate compass, even remove the compass driver, but still error.
There is a possibility of multipath error in GPS (bouncing signal from surrounding), but with easily lock to 5-6 satellites with 10-12 satellites in view, I suppose this can nullify error, as real for positioning, we only needed 4 satellites.
I hope there is someone out there know fix for this..

MIUI rom allows you to enter your preferred satellite under ph settings ^^
Then use gps status app to manage a-gps state - I get anywhere from 10 - 30m accuracy
You are not alone
GPS accuracy on my Defy has been a concern since I bought it. Just like yours, it locks to 4-6 satellites and claims that it's accurate to 4 meters, but my real position is usually a block away. Other symthoms are:
- Accuracy improves with speed and becomes very good when traveling by car, very poor when still or just walking. The correlation between accuracy and speed should be the other way around...
- If there are more than 6 satellites in view, it locks to a maximum of six and then starts "jumping" from one set of satellites to another each two seconds or so. It does so even if the telephone is completely still. I think It should stay with the same satellites while not moving.
As you, I also tried all and every GPS fix script under the sun to no good, even filled a bug report for CM7 back in the day with no luck. It seems that a lot of people out there have perfectly working GPS (o so it seems).
This issue is quite strange though. I have a green lens Defy, and my wife has a Red lens one. We bought them several months apart and they both have the same accuracy issue, so it doesn't seem to be related to a bad production batch. I wonder if its related to geographic position (maybe it works worse in some countries, somehow)
Hopefully its a software issue and can be fixed.
I dont have this issue. Ive actually been sort of surprised at the accuracy of the GPS with CM7... it locks on within seconds (vs the minutes with Froyo). Almost instantaneous with WIFI and GPS on. And it is always accurate. Sorry to hear about your GPS troubles. It could be a hardware problem also?
