I want to use my TouchPro for tracking a long route i will be travelling shortly. When I turn of my device using the button on top when using a gps tracking-tool, the gps will disconnect and need to search for satellites again after turning on the device.
Does anybody know a trick (maybe in the registry) to keep the GPS alive?
I am also curious about this.
Finally I managed to find this thread!!! I am also facing this problem and was wondering if there was anyway to prevent the GPS from closing and losing connection with satellites when the phone goes into sleep mode. Anyone with any ideas PLEASE HELP!!!
Btw I am using TomTom Navigator 7 with Australian maps...

I seem to recall that TrackyPro has a function which will turn the screen off whilst still tracking the route. Is that the type of thing you're looking for?
Well basically I just want the GPS to still have the lock on the satellites EVEN when the device goes into standby. It's frustrating when after 3 minutes (my settings for power management) the device goes into standby and you realise that the GPS is closed when you turn it back on. So yup, as you said correctly, I want the GPS to still function even when the screen is off. Please guide me to wherever I can get the solution as I use alot of GPS!!!
All good GPS software should have option to keep device on all the time while GPS fixed.
I dont think it's possible to keep GPS on while device is on standby mode. Anyway, GPS should stay on even if screen light is turned off for power save.
Well I am using TomTom Navigator 7 with Australian maps, and I have tried looking at the options in TomTom and I couldn't find any setting to keep the screen turned on while GPS is working. And you are correct in that applications such as GPS and Bluetooth are impossible to stay running when the device goes into standby, as this feature is an OEM feature in all Windows Mobile devices to save power. The only way out I see, is to go to Settings>System>Power>Advanced and untick 'Turn off device if not used for...' This way the backlight can be turned off (which saves power) but the device itself is not totally off. This method will still consume power since the device is technically not in standby, but it's probably the best we can get since there is just no way to have GPS to function with the screen totally off ie in standby.

I don't think that TT has the option you need - it takes its power options from the device (including screen brightness). That is probably because TT probably thought most people would have their device plugged in whilst navigating given the power required for navigating with the screen on.
I find that another side effect of this is that if I am driving on a bright day, I need to turn off the auto light level feature of the Raph to make sure the screen is as bright as possible.

I think it's a matter of semantics, but it may help you find a solution faster:
What you need is a tool / solution / procedure that turns only the screen off WITHOUT putting the phone in standby mode. Try searching for that; if you include the whole GPS tracking wish then you might not find what you're looking for so quickly.
Good luck and let us know if you found something that works for you!
Just curious as to what tracking software is used?
Our free PocketReperion tool does keep the device from entering standby mode.
It's free software.

As far as I always remembered, the only time the screen can be turned off is when the phone goes into standby. In other words screen off=standby and vice versa and no other way to breakup this association. The option I have considered is what I have mentioned above, ie just letting the backlight turn off, but NOT turning the device off. But this will be a problem if you need to look at the screen constantly for navigation and cannot survive with just voice navigation. If you really do need the backlight to be turned on all the time, then go to Settings as well and untick the TUrn off backlight option too. Power will be gone in no time, then you probably will need to consider a in-car charger then...

Thanks mate, will give it a test and see how it goes...
Hi, first post for me
I have wanted to do exactly the same thing, that is, keep the GPS tracking on my HTC Touch Diamond with the phone in "off" mode. The only way I have found to do it, is this; play music via a Bluetooth headset (you can pull out the jack-plug too, so no actual sound is heard). Now when you turn the phone "off" the GPS will continue to track.
There probably is some simple software out there that would work better, but this is my solution
Cheers
Perhaps this helps...
Go to HKLM\System\CurrentControlSet\Control\Power\State\Suspend
and create a DWord value named NAV1: with value decimal 0 (0 means power on and here is a complet list of values)
This allos HTC GPS driver to stay on on suspend mode. I think this allows any application accesing GPS to get data while the PDA is off.
Can someone test it and report back?
If this works, i can create a CAB to easily deployment.
Cheers

Hi there, thanks alot for your discovery, will surely test it out later. With TomTom Navigator that I am using, once you have planned a route and it starts to navigate, the screen stays on forever. What I said earlier in my previous posts are irrelevant since TomTom just keeps the screen on and never dims the backlight nor turns off the device. So unchecking the Turn Off Device after XX mins is useless. Anyway we need some fix which can 1) Allow us to turn off the screen to save power but still have TomTom running and giving us navigation instructions and 2) Does not disconnect from satellite fixes when device is put into standby.
Your reg edit sounds like it will work, but will have to confirm it first. A cab file will be really appreciated. Cheers!
EDIT: preliminary testing: Turned on GPS outdoors, managed to get a satellite fix. Did not plan any route. Turned off screen (ie standby), turned back on, GPS signal was lost. Had to wait few seconds to reconnect to the satellites. Unsure about voice navigation while screen is off but since when I turned the screen back on the signal was lost already I don't think there will be any navigation when screen off. In short --> DOESNT WORK.
I didn't read through everyone's response, but what about just using a car charger, and setting the power settings to never turn off when turned on? You can turn down screen brightness if you're worried about the screen itself, but that should keep you connected at all times, and the battery should remain charged as well.
This also avoids registry tweaks that may have side effects. Simple, and painless in my mind.

The change of NAV1: only affect to GPS device, so perhaps the nav software need more devices to stay on to work (or really the soft changes the power state of devices itself). I tested the changes above with HTC GPS Tool and seems to work, but seems navigation software are not the same... sorry.

I'am using the IGO8 Navi Software on my Touch Pro.
I ride by mountain bike often and today I wanted to save the track I normally ride.
I turned on IGO 8 and get a satellite fix and started riding, when I came to my first check point I realised that on stand by mode, the IGO8 wasn't getting satellites.
So I minimised the IGO8 and I had the today screen on. I unticked turn-off device and turned the keylock on.
This was my only solution, it would be great to have the GPS running when switched off.

Trackme has a GPS powersave mode which allows the screen to be turned off but will still record your track. http://forum.xda-developers.com/showthread.php?t=340667
Thanks
Let me check it out.
I used a method found on the samsung vibrant forum that works perfectly for me. Directions:
call *#*#1472365#*#*
choose "delete gps data"
go outside to maximize gps lock potential
choose "get position test"
Now let it do its thing for a few minutes. For about 5-6 minutes it was not getting a lock, but it was detecting between 1-4 gps satellites. Then it all of a sudden the phone got a lock and detected 8 satellites, at which point the phone recorded the gps data. The other forum post said wait until the phone sees 10-12 sats before backing out; my phone only saw up to 9 and locked on 8. Nevertheless, I backed out after the gps data was recorded, and now the GPS works wonderfully in Google maps, places, and navigation. Previous to this, I never got a lock with this phone, now I get a lock in about 5-10 secs. I didn't want to activate using wireless networks because that is not real gps. This is the real deal and easy to do. Try it and report back.
will do. In the meantime, take ur phone on a run with you and see if the gps still jumps within a small radius. I noticed that when i was driving this worked really well but when i try to use it to to record my run route (so i can see distance and speed) it doesnt follow me very smoothly.
I just tried this and my Captivate got a lock on 8 satellites within 4 seconds! Hopefully this will keep working til Sammy gets their update out.

this fix works for me too! However, after a few days you may need to delete the gps data again. Good news is that it gets things working again.
Also, I have had great luck setting accuracy to 150 in lbstestmode. I think this is because the software wont drop satellites too aggressively. As a result, once the satellites are locked, they stay locked - which helps reliability alot.

Only locks into 1 Sat for me. Every once in a while it locks into 2. I think I got a lemon.
I posted a potential fix in the stickey, key value to change is accuracy and using the GPS Test Application....
The OP worked for me as well. I was getting so so GPS locks and would only get a "true" lock if I enabled the phone to use cell towers as well. After the above I get a lock almost immediately and per the test I had accuracey down to 5 meters. Untill a true fix comes out (def seems software related) this is a quick fix that works.
Hoooooooly ****.
I went from getting a lock in about 2-3 minutes to getting a lock in less than 20 seconds. I even rebooted the phone and it still worked that fast. I was able to confirm my lock with GPS Test(app) and using Google Maps to find my position.
trying it now.
looks like its thinking.
will update in a few.
Update
it has 9 and has an accuracy of 10 meters and it jumps to 30 and back to ten.
how often does the * drop on your sats, or do they stay on once locked on?

Update: I get a lock in my house in less than 10 seconds! Bwahaha! Bow before me puny mortals!
I wonder how long this fix will last?
time to lock is not the primary problem with the GPS, I can get a lock within 5 seconds if I opened up GPS test app before I open up navigation. Especially in the house or standing stationary, where it uses skyhook.
the REAL gps problem is maintaining a lock with GOOD (<5 meters) accuracy WHILE moving. Which, I have not seen any fix remedy.

Why would you want it to be less than 5 meters? How wide is the average highway? That's all I need.
Regardless, I'll test it out tonight on the way in to work.
The problem is it can't maintain 5 meters or even 10 meters lock for long. If Captivate can stay locked at 10 meters accuracy, I'll be happy.
Tried in and locked onto 8-9 sats with an accuracy of 10m. Went into GM and got a lock in under 30 seconds.

I believe the problem with maintaining an accurate lock is because the Captivate defaults to having a very high threshold of satellite accuracy. Using the default setting of "Accuracy: 50", it takes a long time to get that level of accuracy. In addition, when you do have a lock, if the satellite drops below this accuracy (even for a short moment) -- the satellite is dropped. This is why you see many satellites being picked up and dropped all the time, and this is why the accuracy ranges so much after a lock is gained. The fix is simply setting the accuracy to 150 (in addition to the other recommended settings) -- which gives the satellites more "room", and keeps them in use.
My theory anyway... seems to work so far
2 minutes after selecting test:
11 sats found
8 locked
Located within 10m, 7 seconds after Google Maps launch.
Okay, this is my first post. I've been reading these forums for a couple weeks now. This is the first and only thing that made mt GPS work correctly. I tried almost every other gps fix I read about but none seemed to do anything. Thanks.

So is this with the stock settings or with other tweaks?
This does seem to help somewhat. I was able to get view 9 sats and get 6-7 to lock. GPS Test app was working and could calculate my speed as I walked across a parking lot. I could even see myself move on maps (never seen it move without bouncing around and such).
I will test later this evening on my drive home and see if I can get google navigation and actual turn by turn to work.

I tested mine using the stock settings bud I had changed the server and port to the google recommendation in previous "fixes".
As we all know, the GPS is very spotty on our Captivate and very often we have problems getting a good satellite lock. However, after work one day I
opened up Google Nav to route myself back home. As usual, Google Nav gave me the usual "Searching for GPS" and it stayed there for at least 5-10 minutes.
Frustrated, I hit the power button and turned off the display. 20 seconds later, the female voice started shouting out directions?? I turned on the display and sure enough I had a lock. Also interestingly, 5 seconds after I switched on the display, the blue circle appeared over my position and I also lost my lock. I turn off the display, lock again. I do get a good lock once and a while with the display on, but if I'm having trouble I'll switch off the display and without fail I'll get one and I'll use the voice prompts to guide me. Anyone else notice this?
I'm running a completely stock GPS settings.
Complete coincidence, would kind of suck for Samsung if this was true.
That's odd. For me, whenever the screen turns off and locks for my Captivate, the GPS shuts down, losing whatever lock it previously fixed if it had one. I always get mad when my screen turns off when I'm using Google Maps as a result...

When you use google maps, yes, the gps shuts down when you turn off the screen. But if you were to use google navigation, the gps stays on even when the screen is off.
I don't remember where it was, but I remember some ceo or engineer claiming that the large screens on most new cell phones were likely to cause major gps issues because of interference. I think it was someone who worked within the GPS industry themself (think: Garmin).
Now I don't know if this person was just speculating or not but it's something to keep in mind.
Well I don't know about anyone else but DAMN! It's true! For me anyway. Screen off, navigate works. Turn the screen on and it immediately stops working and starts searching for gps.

Could be why they replaced the antenna in the Nexus S. A better/different antenna may be more resistant to interference.
TL;DR version:
1)Start Google Navigation, pick destination, start driving. Result: Sporatic or no lock and definitely no turn by turn working.
2)Start Google Navigation, pick destination, start GPSTest, start driving. Result: Almost constant lock and turn by turn works astonishingly well.
What gives?
Alright, please read this whole post, try it out, then comment on whether there is something to this or maybe I'm just crazy (a very definitely possibility). I was playing around with the GPS today and tried the Vibrant GPS hardware fix (pulling up the contact so that the GPS antenna is making better contact with the metal back). There wasn't much of a difference, so I decided to take the back off and run the GPS without the metal backing. I found that interestingly enough I was getting a better SNR with the back off than with the back on it was 8/8 at about 25-30 with the back on (using GPSTest) while with the back off it was 8/8 with 30-35.
Now comes the really interesting bit. On my drive home today I decided to see how well I could hold a moving lock. I turned on Google Navigation, pointed to my house, and started driving. Needless to say I was not able to hold a lock for very long. However, if I left the navigation app running and started GPSTest, all of a sudden I was getting the turn by turn voice pretty accurately. I then exited GPSTest and probably 10 seconds later lost my lock again. Open GPSTest, BOOM lock back on and turn by turn working again. Am I just hitting a really lucky coincidence or is GPSTest doing something we're not aware of? Please post here if you can either a) replicate what I'm seeing or b)think I'm blowing smoke cuz you aren't seeing a lick of difference.

BTW... this is GPS Test by Chartcross Limited, NOT the one by Mike Lockwood. You're welcome to try both however.
Previous GPS threads have repeatedly documented the positive effect of moving your nav app to the background. Theories on it center around backlight, temperature, or CPU/GPU. My own myTracks tests seem to point towards CPU/GPU. Or, at least, they seemed to rule out temperature or backlight as a factor.
So did you have GPS Test in the foreground during this test? This will pretty consistently give you improved performance over having Navigation up. If you turn the screen OFF altogether, it almost works as well as a real GPS! Check out the difference by recording a few drives in MyTracks -- it's night and day, on my phone at least.
My personal, uninformed theory (guess) is that the CPU/GPU and screen during Navigation are starving the GPS subsystem of power, causing either reception issues or causing the clock to desync and lose the position of the satellites it's tracking.
Ah well, such is life.

I noticed this as well with my old setup (phone bought in August 2010 running Cognition & JK4 radio firmware). I got one of the refurbs from the random power off fiasco and GPS seemed to be just as unreliable. I've recently flashed the JL2 radio firmware, and GPS locks on within seconds and stays locked around town - as it should. I think a lot of people's issue would be completely resolved if they played around with radio firmwares...

Yeah, GPS Test was in the foreground, navigation in the background. I get the feeling however its more to do with the application than the hardware. I say this because having other apps in the foreground doesn't quite have the same effect for me. Is that the case for everyone else as well?

this worked really well for me. am on andromeda 3. but was getting on locks without staying on continuously. with the approach. gps was spot on.!! a BIG Thanks
I've noticed this for some time when running the GPS Application Test in lbstestmode. Run the GPS test first and then move it to the background and launch your normal GPS program and you'll usually be better off. Needless to say, I'm doing another warranty exchange in hopes of getting one with better GPS hardware soon.
Try this:
Get a mobile hotspot (or someone who has wifi tethering enabled on their phone). Put your phone into flight mode, then turn WIFI on and connect to that mobile hotspot. Fire up navigation, and go for a drive. You'll be amazed at how accurate your GPS is.
That leads me to believe that there is an interference issue in the GSM/GPS antennas. Part of the reason why putting navigation in the background helps improve the GPS performance is because it stops refreshing the map, which means it's not trying to use the GSM radio. But if you fire up Pandora, even with Navigation in the background, the GPS will start going nuts again.
I'm pretty sure AT&T is aware of this, and I even think they have a... well, not a fix, but a way to mitigate the problem.
A friend of mine did a warranty exchange on his Captivate last Monday for a problem with his USB port. The Captivate he got in exchange has been getting much better performance with it's GPS. And since his worked just fine all week, I exchanged mine yesterday. Now, quite often after flashing a new ROM, the GPS will work fine for a day or three. So I'm not going to be convinced mine is working as well just yet. But there are some notable differences from what I've seen before... When I'm tracking my position on Google Maps, my actual position now stays within what the GPS reports as it's error, even when I'm driving around. Previously, my phone might report a 10m error, but my actual position might be 200m or more from where it thought I was. In addition to that, I'm seeing that my phone is locking into more satellites, and holding that lock even as the SNRs drop due to obstructions. And finally, my GPS works just as good while it's in the car dock, whereas before it would only intermittently get enough signal to fix a position. Overall, while my GPS still isn't as good as other phones I've had in the past, it is now actually good enough to use and trust.
I think that AT&T isn't advertising this because it's not something that they can push out over the air or through a Kies update. I'm guessing that either they modified the antennas slightly, or that they installed a new firmware to the GPS chip (at a lower level than the driver)... or maybe both.
Either way, my friend's GPS has been working great all week long, and mine appears to be doing so as well. I'll not say that it's permanently fixed yet, but I'm cautiously optimistic. We'll see how it's doing after another few days go by.
UPDATE 3/28:
Two more days of testing have passed. So far, the GPS is holding up nicely. The only issues are with the car dock. When the phone is in the car dock, the GPS will occasionally drift 5~10 meters off of my position. This doesn't really surprise me, as the electronics in the car dock are right up against the GPS antenna, and simply putting the phone in the dock will drop the reported SNRs by more than 25% - usually a lot more.
Still, even with the car dock, the GPS is perfectly usable. And without the car dock, the GPS is now exactly what it should have been from the get-go.
I've also found that if I run either gps status or gps test to get the fix, then start whatever app I need to use, the performance is much better. Recently I just use lbs test to get the fix, then proceed with whatever app i need to use. Seems to work better, as lbs test continues to work in the background
i have seen this in the past but trying to prove that it is not random has been a problem as i cant repeat the results.
also i dont thing i have ever observed the phenomenon while using control plane mode.
maybe another coincidence, i cant tell but i have been using the control plane version of da_g's fix for a couple months now in combination with the jl3 modem and have gps that many smart phones would envy. i find jl3 to have the most stable positioning and tracking, less blue circles ect. i also find agps settings to hinder tracking. i only set agps mode to standalone. not sure how supl works or if controlplane supl setting is actually doing anything because i was under the impression that supl was part of agps but it is a combination that started working for me and i am sticking to it.
GPS sucks and I think it's my phone.. GPS won't stay awake and keep the lock, needs wifi assistance and loses the lock as well. Google Maps navigation has been a nightmare.. dropped my phone too many times maybe?
With wifi assistance off:
GPS Status will get locks, up to 9 sats usually at best.
I have seen it lose locks.
When I close apps that use GPS the GPS icon disappears from the status bar.
I have seen this happen over multiple roms.
I have wiped my phone completely, no difference.
Google Maps navigation is terrible, often get "waiting on location" even before navigation and also get that my location is not available wifi on or off.
Any ideas?
I say maybe a equipment problem, I use my GPS daily for work and it works flawlessly everytime....

+1 Going to have to agree with Rooster. If your having the same issue across multiple Roms, it's probably an equipment issue. Unless your changing the exact same thing on every Rom to affect GPS. Although this is unlikely. This is also based on that fact that I use my GPS daily. It locks in under 30 seconds everytime. I haven't touched a thing, having to do with it
Same Problem
I have the exact same problem across multiple roms (Cyanogen and Supreme Sense). I just re-loaded the entire phone. The gps still seems a bit fishy. Did you find a solution? It did work just fantastically when I first got it.
Thanks in advance.
