GPS dead? - HD7 General

My HD7's GPS ('my location' doesnt work, nor does the free 'GPS' app.) doesnt seem to be working.
I dont have a 3g network, and my GPRS doesnt work thanks to the failure of HTC's connection settings app as well. But even over WiFi, the GPS fails.
Is that how it is? Does GPS required GPRS/3G to function?! If not, should i return my HD7?

ok GPS app now works and shows some altitude/longitude.... but the Maps 'my location' still fails. :/ any ideas?

i've got 3g and still refuses to work
anyone?

HD7 uses aGPS
Unfortunately, the GPS capabilities of the HD7 have disappointed me as well. In actuality, the HD7 uses assisted GPS technology which requires a signal from nearby cellular towers, preferably three towers or more, in order to triangulate the position. Also, currently no external true GPS can be used, at least via bluetooth, since the bluetooth profile on wp7 only supports hands-free audio.

Assisted GPS

Is this function in our Kaiser? I've enable it from the Kaiser Tweak but today i tested it when i was in a tunnel....it did not work at all and the tunnel was 4 KM long....it should have had enough time to get a fix if it was working.
Is the Assisted GPS what i think it is?
How do you expect to get a GPS fix in a tunnel???
AGPS is basically what the QuickGPS app. does: it downloads sat. data (satellite locations) via a network connection from a server, so that TTF (time to fix) is reduced, since the device doesn´t have to download above data from the satellites themselves - which is slow....
Hope I was not too unclear, doing a search will give you much more and detailed info about how GPS works......and it doesn´t in tunnles....
As mentioned above, the AGPS uses server information (via cellular network) to locate the GPS satellite for a quicker fix and hash conditions. For a 4KM tunnel, I'm sure that your phone would have lost both GPS and network signal.

Thats correct, there are som applications that tries to estimate where in the tunnel you are when the fix is gone. But I suppose this is a function of the application and not the GPS hardware
I stand partially corrected........ http://en.wikipedia.org/wiki/Assisted_GPS

Which is why the title is "Assisted GPS".....I've done some search on AGPS and it's suppose to use the cellular to still get a fix when in the tunnel. Well....i read it sometime ago way before Kaiser was out and this was actually one of it's talked about feature in Kaiser. Using the Kaiser Tweak, one can enable this feature but i've tested it today in the tunnel with strong cellular signal, the GPS is dead until i came out of the tunnel.
I guess it also has to be supported by the particular program. Many TomTom PNAs have a dead reckoning mode which shows your position in a tunnel based on your "entry" speed for about 30 seconds, than the position freezes in the tunnel. Now that of course has nothing to do with AGPS, but it´s a way of overcoming temporary signal loss.
Best way would be to have an inertial sensor built into the phone like in fix-mounted car-navs......but then again, that would be overkill....
You have to remember that the Assisted GPS (Cellular network mode) relies on the fact the network itself supports the feature. I know most in the UK don't have it turned on in general use. They only allow it to be used by emergency services and the likes.
Perhaps that's the same in your country?

Probably so.....oh well....it was worth a try
Thanks guys for the input.

Any way to force google maps/kaiser to use wireless traingulation instead of the GPS

So the internal GPS is one of the primary reasons I wanted the Kaiser, but when it comes down to it, it's the rare occasion that I actually use the GPS for much, especially stuff outside of basic "where am I" and "how do I get there" with gmaps...
Even when using quickgps, sometimes when I need to know where I am in relation to somewhere I'm going, quickly, it can still take way too long to pick up sat signals. I was in the car with a friend the other night (this is a guy that I constantly harass for having an iPhone (and he harasses me for the opposite)) and when we both pulled out our phones with gmaps, he knew right where we were, instantly, while all I could do was sit there and try my hardest to not make excuses about why I wasn't picking up a sat signal quickly.
Unless I'm using other GPS software, for my uses with gmaps, I'd really rather just be able to use the triangulation that non-GPS phones use. I tried turning off the GPS (GPS program port: None) in settings, but gmaps just searches anyway, not finding any hardware and/or sats.
Is what I want to do possible? I'm sure I'll get several responses on how I can speed up my sat signal pickup, which is NOT what I'm looking for. I just want to be able to use gmaps "My Location" without using the internal GPS, thus saving battery as well as getting a quicker pickup on where I am...
TIA

Yes, what your asking for is just using "My Location" without GPS. I use "My Location" all the time it does not activate my GPS. Here is an article that confirms "My Location" does not use GPS.

I know that My Location can be used without GPS, I'm just wondering if it's possible on a Kaiser. Assuming you have a Kaiser device, what and how do you have it set up so that gmaps doesn't activate/use GPS, but instead uses the cell towers?
On my device using GoogleMaps 2.0.0.11 the option for My Location works separately from Use GPS. The location (within 1.7KM) is picked up within seconds, GPS does take longer but is accurate to individual rooms within my home. The Cell based locator is obviously dependent on your Carriers Cell towers and I know in the past I have been unable to get a location over HSDPA or 3G but GPRS worked. Now though on TMobile UK at home I can get my cell based location using any non Wifi data connection.
Smack! Smack!

Ah, my apologies. Turns out I was not using the latest version. I've installed v2 with separate GPS/My Location, and My Location without GPS works great!
Thanks to all.

By default My Location DOES NOT use GPS. You have to enable GPS from the menu.
Yes I have a Kaiser (actually 2at&t Tilts) and use Google Maps (v2.0.0.12)

Yes, I found this out by installing the latest Google Maps (after my last ROM flash, I installed gmaps from a cab I already had on sd, which was apparently not a recent version).
Thank you - I love the fact that I can use gmaps without GPS now for the quick "where am I" without having to wait, but can still use GPS when I feel like it, and also still have it enabled in Settings for use in other GPS programs.
Thanks again

Disable Data and Keep GPS? How do you do it?

I have two questions really..
I live in the Netherlands and have an always-on internet subscription... but when I travel abroad I want to do the following:
1) Turn off all data transfer so I don't get charged for things that want to update or whatever
2) Keep the GPS functioning
Using the connections manager, I turned the data connection off, but this didn't work at all. It would just connect through the phone line anyway. I resorted to deleting all the internet settings from the phone which was a difficult, lengthy and frustrating process, and I ahd to put them all back in when I got home.
Also, after I did that, GPS did not work anymore. I could not find a setting anywhere to turn on or off the GPS by itself... is it linked to the data connection? I couldn't actually turn the data connection on in the connection manager when I deleted the settings... I couldn't access the GPS at all from any program unless I had the data connection on, and working. Is that right, and... isn't that weird?
Yes, it's weird. I faced same problem. Solutions?
To totally prevent data connections, you have 2 choices:
1- remove GPRS/3G configuration from provider
or
2- nodata! That's what I use
About the GPS not working while in fligh mode, I turn on bluetooth and then GPs works
or alternatively rename the access point name...
e.g. mine is "orangeinternet" I stick a character in front "xorangeinternet" and thus it fails to connect if you do accidently start up an app that tries to connect.
I know it works for Orange - cant confirm it with other providers but I suspect it will be the same.
Can anyone else on other provider networks confirm?
nodata is quite handy
Nice, I'll try nodata!
The GPS eludes me though.
Use "Advanced Config 3.2" Available on this site.
Menu->More Settings->Connections
You can disable each network connection. does not affect GPS
To use solely the GPS you need to install a specific GPS enabled stand alone software on your phone, such as TomTom or IGO.
Otherwise you will be using a AGPS data connexion which is expensive abroad.

actually it does... tomtom7 doesn't work if you're in flight mode (no problem with igo8 thou).

Does 3G, HSDPA, Edge each affect the GPS in anyway?

Me and my friend were arguing whether or not theres a difference between searching for satellites on a 3G/HSDPA and an edge connection.
Is it faster or do they have no correlation at all?
3G/HSDPA/Edge is not necessary at all for gps
gps is a 1 way communication between a passive receiver in a device and a geostationary satellite out in space
3G/HSDPA/Edge is a 2 way communication between a device and a ground based transceiver and antenna setup
in theory you can pull out your sim and throw it in a well
and gps still works
but with assisted gps which x1 support one can get a faster pos by the device getting a rough position from the 3G/HSDPA/Edge connection because they know their own location

[Q] WiFi Only GPS Questions

I was curious as to why there is a button in the notifications menu to turn GPS on and off. I started to look in to it and discovered that there is indeed a GPS chip in the wife only version, or there seems to be anyway!
My question is, what does that chip exactly do? Does it only pick up your location? I can't seem to find any places around me with wifi off. I'm assuming that means all the map and location data is delivered over the internet through 3g or wifi. Is there anyway to use my device as I would a regular GPS device? I know it has all the features but can they work through the GPS chip like they do in a GPS device? Or is there anyway to get this to work?

Ok the wifi is mainly just for accessing networks either open or via ssd and password. You can also connected with mobile AP if your mobile has this option.
The GPS on the other-hand is for mapping and location based services like navigation etc (you can use copilot and several other gps based apps with the P1010). Some of these apps will also piggy back any Bluetooth and or wifi connections that are available for further triangulation if needed. So if you have any apps like various weather and navigation then the GPS is required (but also your location can be shared via your wifi and opt in to give this info through google).
Hope this helps

you can find your location via wifi, enable your wifi and turn gps on, you'll find your coordinates, but not that accurate compare to 3g
