I'm not sure if my GPS is defective. Please help...

If I use it while I'm driving (with TomTom) seems to be working fine.
However, if I use it while I walk, sometimes the position doesn't update even if you walk for 30 seconds. After that, you get a new position. Then it works for a few minutes and I stop getting new positions. I have to wait a few seconds again.
I have tried in different places (no tree cover) and with different programs and I got the same problem.
Anybody had a similar problem?
Thanks

Don't worry... Your GPS works fine.
This GPS is not intended to work while walking. The reason is simple: it needs a minimum of speed in order for it to calculate the direction you move in.
That's why it works on the car and not on the "walk".

I can't remmeber the details, but I think GPS has a error range of.. 15m or 50m, from which you may have problems. As such, if you were to walk a long enough distance, it ought to update itself.

I'd have to disagree, at least as far as my device goes. I use iGuidance software, AT&T Rom, and everytime I take the dog for a walk (three times since I got the unit) I bring it with me and do a walking nav test. It works perfectly everytime.

It's not defective, it's due to a feature of GPS hardware to prevent erratic jumping around due to accuracy errors. For more info, go here and search down to where it talks about "Static Navigation".

Once of the reasons I got this phone was for the GPS, because we like to do geocaching. However, unless my phone is defective I won't be able to use it for that...

Not unless you can find a way to disable static navigation. While I'm sure this isn't an acceptable solution, I've found that if I shut down whatever GPS application I'm using (such as google maps) and re-open it, it does seem to reinitiate GPS and update to the current position.

I hear people talking about the GPS on this phone and I have to say that I find it to be amazing. Here are a few of my happy stories.
1) I got 4 sats inside of a hockey rink yesterday
2) On google maps if I zero in on my back yard I can tell if I moved from one side of my yard to the other
3) Tom Tom, Pocketstreets, WindowsLive search and google maps all work great with out any issues at all.
People have to remember that it is a phone not a camera (although it does well at that), not a guidance system for missles requiring 1cm accuracy. It is a phone and a damn good one if you ask me.

Thanks a lot for the information. It helped me a lot.
However it seems that there is not a way of disabling Static Navigation for this model of GPS, right?

I don't know. I guess someone would have to discover how to do it, if it's even possible.

I can to some extent as well. But if I move from one room to another, it doesn't update unless I close google maps and re-open it. That is the issue the OP is having... when traveling at low speeds, you have to travel a relatively long distance before it updates. But I've found it to be extremely accurate using navigation software in the car, which is what static navigation optimizes for.

HTC TYTNII GPS Problem
I got my TyTnII when was lauched 2 days in Malaysia, replaced with the second unit, still the same problems, the GPS dun work.........
So waiting for the second release. anyone having the same problem?

...........................

Anyone have a fix for the Quick GPS problem?

I have tried modifying the registry to the values that should fix it but it does not fix it for me. I still do not get an update. Any ideas?
Thanks,
Dan

I ended up hard resetting my device, I'm sorry to say. When I first got my phone, I ran QuickGPS and it downloaded some data. Ever since then, QuickGPS would not work and neither would my GPS. I tried everything I could find, including *gasp* going into the External GPS settings.
After hard resetting, I will not run QuickGPS again. All I did was fire up Windows Live Search and let it find the satellites. It only took a couple of minutes and I was up and running.
That was 3 days ago and my GPS is still working. Any GPS capable app I run takes less than 30 seconds to get a fix, even inside my house. I have not run QuickGPS since then and I don't intend to.

How can it work inside your house? I do not think that is even possible. Satellite receivers are line of sight. Try putting a direct TV dish in your house and see what kind of reception you get.

Yea I was doubting that too. GPS doesn't work in my house, as soon as I step outside, boom, its on.

It works indoors at my place. Its not line of sight, otherwise even the phone case would be blocking the receiver. However it works much better outdoors. I think the reason is the radio signal from the satellites is very weak and doesn't penetrate obstacles very well.

I have a few windows in my house and I get enough of a signal (usually only 3 or so birds) to track my location. It's good enough to get an initial fix.
.:Christian:.

sad to hear that it doesnt work for some people.
ive used it from the beginning and it works fine. no problems up to now.
"thats not even possible"
cmon... i was surprised, too. but it works in my room (under the roof)
quality is weak (1-2 satellites) but it can get your position.
of course radio or gsm both have more sending strength but they also work in your house, dont they?

hi, hmm.. i have got no problems with GPS at all and to be precize i was really suprised with the speed lock. i instaled tomtom fired it up and then set it up with other NMEA GPS receiver and my device found the signal in 5 seconds !!! and i got 5 satelites in range ...aha im in my house ..maybe cos i am a student and the glazing is single

Google Maps 2.0 with My Location - no need for GPS?

Just tried the new GMaps 2.0 and my location works flawlessly.
Called "My Location," the feature comes as part of the release of version 2.0 of Google Maps for mobile. My Location uses cell tower ID information to determine (approximately) where you are. Google says that it uses special "Google-developed-algorithms" to determine this, which sounds like fancy talk for triangulation (a supported phone can determine how far it is from the three closest cell towers and then pinpoint the approximate spot of the caller).
Anybody else tried it?

Did you try while driving ??
(I'll still keep my GPS chip for a while)

It's better than nothing but not very accurate. On my Kaiser, I will continue to use my GPS.

About to will update when I get back

Just tried it in the UK and the location thingy is temporarily unavailable.

Yes, though when I'm on 3G towers it gives the "temporarily unavailable" message, works when I get an EDGE tower - 1600meter granularity!
Great feature, very cool, will not replace GPS. Our 3G towers just came up last month so that may be why they're not in the Google database yet....though I recall other reports of 3G location not working.
Richard

Didn't work for me either, I'm in the UK (south wales)
Did notice the GPS location is a little more accurate with 2.0
Tended to jump a lot with the older version

I heard it was only good to a 3 mile (4.8km) radius. Not nearly good enough to give you turn by turn directions.

No, even google's site says the accuracy is dependent on the cell tower spacing. In my case, at my desk at work it reports 1600m (1.6km) accuracy, so definitely not turn-by-turn. In a densely towered (urban?) area, I suppose it's vaguely possible to have sufficient accuracy for rough turn-by-turn though.
Richard

Still, GPS is obviously much better.
I would have appreciated this with my older non-gps phone though and I am hopeful that they will offer this as an iPhone update for my wife.

I've tried the Navizon version and it can be a lot better in urban environments where the cells are far smaller. In most of central london, Navizon can get a fix to an accuracy of a hudred yards or so. I have seen it do better than GPS since it is less vulnerable to the "Urban Canyon" effect. In rural areas, the coverage of each cell is much larger and I would expect the accuracy to fall to half a mile or worse.

I live in Minneapolis. AT&T rolled out 3G here on 1 November. I loaded up GM2.0 and it was right on the money. I was even inside my house.

I don't see how the program could triangulate a device out in the suburb. In a metro, yes, it's possible. Satellite GPS navigation is not going to be replaced anytime soon; however, I can see the "traingulation" come in handy for emergency situations.

It doesn't matter where you are, suburbs or metro. If you have 3 antennas, you can use triangulation, period.
While it's not good for turn-by-turn navigation, it would be good enough to get a quick fix and be able to search for something in the immediate area.

Try thinking of it as a tool for people without gps. Imagine you're lost and you can get a general idea of where you are. Then drive a mile and do it again...now you have a bearing on where you are headed.
This won't replace gps or give you directions until it can get to that accuracy.

I just install it, and i was coming on here to create a thread but looks like someone beat me to it. gMAP just got a whole lot better, I was like oh sh*t it uses the cell phone towers to show my location. this the bomb. google stepping the game up.
Mine works great on the 3G but i do get that unavailable bar sometime.

so for those of us that like the way the old version works with 'track location' gps feature, is the new 2.0 version beter or just stick with the old ?

It still works with GPS, but you can also get a quick location fix via cell towers like people have been discussing.

Built in GPS not working anymore

I do not appear to be able to use my built in gps in this new version of Google Maps. The settings are identical to my previous installation which worked flawlessly. The cell based location does appear accurate on my initial tests. But if I turn off the gprs or 3g radio and switch to wifi I am unable to get a fix at all.
I broke my own cardinal rule and overwrote my backup of cabs so I cant reinstall the previous version, Doh.
Does anyone have a copy of the previous version installation cab? Or is there a trick to using the Kaisers built in gps? as I said earlier my settings are setup the same way as worked previously.

2.0.0 works fine on my Tilt, as did 1.7.1 - both with the GPS Options set to let Windows manage the GPS. Way back when I had to tell it COM4: to get Gmaps to work, IIRC.
In any case, 1.7.1 can be downloaded from Google here:

HTH,

Tilt GPS sometimes does not receive satellites

Using IGO (legal).
This happens with the new standard AT&T ROM, and with the previous one as well.
IGO starts and quickly obtains satellites, then every now and then, without any obvious reason, I get a verbal warning that no satellites are found, and the GPS icon turns red.
After a few seconds, or even a couple of minutes, GPS signal is restored.
The Tilt is positioned near the windshield, and the problem does not occur in "urban canyons".
I don't have any other GPS app with maps that I can use to check this.
I'd appreciate any ideas.
Thank you.

You could try a free app like Microsoft Live Search or Google Maps to check against IGO. I haven't really noticed mine dropping signal unless I do go into a real canyon or something like that. One thing - when the phone goes into Standby, the GPS chip turns off for battery conservation. Is it possible that your phone is going into standby when you lose signal?

mine does the same after update to the new att rom, and honestly, i dont have an answer for you.
Live search cannot ever find any satalites, which is why I have resorted to using Google Maps. It works fine for me. So try using google maps. its works much faster and more reliable in finding sats, imo.

try a different radio. it has been reported that it works for some.

replies
snooginsguy: No, it always happens when navigating.
grandpareza: not sur ethere are googlemaps for my country (at least not with any reasonable resolution). Will check later.
P1Tater: Replacing the radio requires HardSPL, which I haven't sone yet. As I said, I'm still with the original ROM. I live abroad, so there's no issue with warranty. It's just that I'm concerned I might brick my device.

i heard that you have to update with quick gps everytime before you use your actuall gps... that would improve the sat tracking a lot better

It's on auto update
So that's not the issue.

GPS issues?

I cannot get my Streak 7 to get a GPS fix - at all. Anyone else have this problem? I've seen it on Dell's community site also but Dell is of no help at all. They don't even have a proper support page for the Streak 7 set up yet. Typical. Well, eBay might be my next stop, losing a few dollars is worth it to get rid of the frustration-induced headache...

I tried indoor, wait for long time for GPS fix. but outdoor I had no issue. It locates me fast and voice command is accurate to guide me to destination. I will try extensively for my short road trip today, but so far it was ok.

Did a little more GPS test.
I think to purely test the strength between GPS receiver between your two devices, I would recommend "GPSTest" app in the market.
Then let's
1. Disable all data connections (put it into airplane mode)
2. Only enable GPS
3. Put them side by side at an area covered by GPS satellite
4. load GPS Test and press Start from option menu.
You can compare
SNR value displayed from both devices to see the performance of their GPS chips.
Note: PRN here means the number of Satellite assigned to the tast. SNR is signal-noise ratio. The higher the better of course.
Because GPS signal is one thing, Maps is another. So Google Maps/Navigation apps need data connection otherwise they cant process data received by GPS chips and put into a user-friendly map.

One discussion thread in other xda forum about GPS testings:
http://forum.xda-developers.com/showthread.php?t=750945
Hope it helps.
btw, if you don't have a 3G/4G plan, in outdoor where wifi is not available, the stock nagivator will NOT work. There are , however, some "pure" GPS apps in the market you can google about them, which requires only GPS connection since maps are already stored in those apps.

btw, my Streak 7 GPS signal test gave me
SNR=35
SNR within 30-35 I heard is generally acceptable, above 40 is exceptional.
For civial usage standard, i mean.

There seem to be some bugs with GPS indeed, it got a fix in my office yesterday, but when I drove home, nada. Rebooting the S7 set it straight.

No fix again today when I headed out and barely any satelllite activity as verified with GPS Test. Tried a reboot, no improvement. Never had that problem with the Tab. I think the S7 is going back...
