new the the Android, GPS question.

Im getting some rather odd performance from the GPS..
I just got this thing out of the box, and know next to nothing about it.. so forgive me if this is a known issue or an easy fix..
I decided to mess with it a bit and went to "maps" and then "location" it puts me nowhere even near where I am..
so I tried "direction" and did "from my current location" to my office (4 miles away)
it cam up with sound direction, but when I started moving, it had my dot jumping all over the place. Showing me on one side of town, then 30 sec later 5 miles away..
I download an app that shows GPS status, and it shows good signal (7 satellites)
So, why is it behaving so wierd?
also, what are some other GOOD free navigation apps? I see many listed in the market, but I dont want to download them all, anyone have an opinion?

Do you have the GPS enabled in your settings?
G1 uses 2 ways to pin point your location:
1. Wireless networks (which I find never to be accurate)
2. Gps
Go to your Settings>> Security & Location
Try disabling your wireless and ONLY use GPS
Sorry but no good FREE Nav on the market yet, AndNav is still on the works for US

don't know how good it is but Nav4All i think it's called....i downloaded it this morning and i think it's a talkin nav cause you have to download the voice language you want to use. i haven't tried it yet but might be a good option

I saw TeleNav nominated as the best GPS navigation app by the Android Network. (this is their blog page where it is posted: http://blog.telenav.com/blog/2009/0...ne-vote-for-us-in-the-android-network-awards/). Should I get this service or is some other service like Google Maps available? Thanks for the help.

i use this... confusing at first but ya you can have the voice different ways. i gotta guys voice bc i have a feeling a girls voice will point me in the wrong directions...

The ONLY good nav program is copilot. All the others offload navigation to the provider's servers so require network connection and use up your data allocation - i.e. cost $$ to use.
If your location is jumping around by miles, then you are using cell tower location. It sets your position to the same position as the tower itself. GPS lock can sometimes take a long time. If the gps icon in the status bar is BLINKING or OFF, then you are definitely NOT getting a GPS position.

if you have unlimited data, you're ok with the others. I used nav4all before i bought copilot. copilot is MUCH better, but nav4all does the job well enough.

HD7 GPS issue???

I notice my Bing Maps doesn't show the right coordinates of my location. What could be wrong?

You could be standing indoors or somewhere where there's not a good enough GPS signal, or you may have location services switched off.

You are not alone. I started a thread where I called it =garbage. I don't want to generalize just in case it's a hardware issue on my part but it always shows my location in a different city and when using the GPS on maps it seems to always be trying to catchup.

GPS settings
How can we tell if the GPS has locked on to any satellites...or for that matter, if it's even on??? There doesn't seem to be any direct mention of GPS in the settings menu...just a general option to turn location services on or off. Am I missing something here...or does ms not think that giving users direct control over GPS is important?

Totally agree with you. My guess though is that when the circles radius is just a couple pixels from the central point then its GPS; since GPS is accurate to a couple feet and A-GPS when the radius is about half the screen. Again just guessing but I really do wish there was an option.

I believe you're right about the meaning of the radius of the circle in the stock map app. But, it probably isn't as obvious in other kinds of apps that use GPS.
I'm gonna shoot ms an email regarding this...and I suggest that anyone else that agrees that this is less than ideal do the same. Its too late to have them do anything about it in the upcoming January update, but if they hear enough complaints about it, maybe they'll do something about it in the update after that one.

Personally I'd rather Ms did NOT add in any such options. I have the option to use or not use location services, that's enough. Apps that can utilize GPS will switch the circuit on and use it while they're the active app. As soon as you switch away, the app tombstones and GPS switches off, to save battery life. That's just the way I like it, nice and simple. No need for an option of any kind there. It just works.

Jim, if the battery on my HD7 were more robust, I would agree with you. But it's not...so I don't. I would like the option to utilize only tower/WiFi triangulation...and to be able to enable my GPS only when I need my location to be precisely determined.
You are right...it does just work...which was more than I could say for my Vibrant's GPS for quite a while. But, access to any setting that could help me milk some more life out of my battery is access that I want.

GPS ?!?
I have both the HD2 and the HD7. The HD7 with services ON show my location over half a mile away from my office. This is consistent and constant. It shows me in the middle of a hwy norht east of my office. My HD2 not have this issue. It pinpoints my location, tells me in meters how accurate it is and tells me how many satellites it is in contact with. It will actually follow me accurately around the building inside and out. What's the problem with the HD7?? Seems like it is a step backward to me in this regard!

How wide is the circle around the dot? It may be using the Cell tower / WiFi to determine your position and therefore be very inaccurate.
What country are you in?
I guess it's possible that the actual maps are wrong and are showing the incorrect map overlay for your country?

after reading this thread i tested my HD7 with the bing map and its accurate, showed me where i am i changed to aerial map to confirm it...
i believe the data (3G) have to be connected, i am on unlimited data plan so its on all the time, wifi do not work as i tested with the wifi after that and it showed my location far away from my home...

this should fix everyones issue Go to setting and select find my phone check box both opitions and now try bing maps again. you will also notice well driving bing maps will keep a better track well your moving

did that and it now works perfectly, previously it was over a mile off my actual location

Me living in Thailand, whenever my HD7 connected to WIFI (no matter where), the current location always changes to San Jose. I have no idea why this happens ?

hd7 no gps please help
gps dosent work on google maps when i flash back to old rom gps works

As far as I know location services do not use GPS exclusively. It uses GSM cell and tower info as well to speed up approximation and let enough time for GPS satellite locking. GSM cell data is stored in internet databases (do not know where and how) but if there is a mislocated tower (e.g.i Thailand) your location might be determined in a wrong way.
To keep it simple M$ hidden this mixed mode location service. I don't know what happens if you switch off location service in settings and use a GPS application for locating yourself. Is there a difference? Might be.

GPS Question

I was wondering, are maps in Navigate and Google maps stored in the phone or does it need an internet connection to work? Let us say you went on a road trip to some off-beaten place, where you do not have any signal from AT&T. So at that point, will the GPS still work? I mean i know the phone can still communicate with the GPS, but can you phone display the maps without the connection to AT&T?
I know GPS's like Garmin etc, have the maps of the entire US stored in it memory, so no matter where you go you get to see the map of where you are. TIA.

Google navigation needs a GPS signal to work but if you dont have one, what will happen is the directions will still be there, but your location wont update to your position.

you do need a data connection to use google maps and such.
i use copilot live and really enjoy it.

Thanks for the replies, so if I am getting this correctly you do need a data connection to fully use your phone GPS, otherwise it can probably still give you some text/voice directions like turn left in 200 feet, etc. but with no visible current maps (if you do not have a data connection).
The simple reason I was asking this was to see how much a phone GPS can substitute for a true GPS, like when maybe need to use it in some far-off place like Yosemite park, etc. Looks like from the answers so far the phone GPS is quite limited.

In my experience, Google Navigation cannot calculate your route without a data connection. The program will stay at "generating driving directions" until it times out and throws a network error. You can't really do much with Maps or Navigation without the data connection.
As far as map storage, Google Maps will cache certain map tiles that you recently (or habitually?) loaded, but Navigation will not. I'm not sure if Maps will even continue past startup with no data connection at all, though, for example with the phone in airplane mode. It seems like it would tell you that you need a connection. I can't remember what it actually does.
If you try to use Maps with no GPS, it will tell you to enable it and calculate your position based on wifi networks and cell towers. If you don't have any RF enabled, it can't tell where you are. Navigation, if it has a tower location with no GPS fix, will give you a top-down map view and tell you to follow the indicated route, and won't give you voice directions.

I loved the Garmin GPS products. Having maps offline with no need for data was fast and reliable. I wish they would make an Android product.
Oruxmaps supports offline maps but has no navigation capability unless I'm missing something.

I use MapDroyd for GPS without a data/cell signal. You install the APP, then you can download maps and store them on your SD card. You'll have maps/GPS anywhere. No need to worry about having a cell signal.
Just download the maps prior to heading out of town. You can download maps by state. I keep Oregon and Washington maps on my phone and never worry about GPS out in the midde of nowhere.

google nav needs to download the map at the time you start the trip, once it has a route the map is there but if you miss a turn it may have trouble recalculating without a cell signal. if there is public wifi it might work.
there are a number of apps in the market that are one time pay (unlike i phone where many are subscriptions) that store that maps on your phone but they take up massive amounts of space and take forever to download the maps. i have succcess with navdroyd, the gps quirks of this phone may prevent some apps from working well depending on the base rom so test it imediately in case you need to get a refund.

[Q] *sigh* I have had enough... Does this phone have a real GPS receiver or not?

I'm getting sick of ignorant people saying stuff like "oh yeah your GPS works as long as you have a data or wifi signal."
NO. THAT IS NOT GPS. That is the cheap triangulation signal method via cell towers that just about ANY phone can do. If you don't know the difference between GPS and cell tower triangulation then do not bother contributing to this discussion.
Real GPS uses satellites. You know, the ones in space. Nothing else.
Tomtoms don't use a cellular signal, they use GPS.
If you have real GPS, you can pinpoint almost perfectly where you are in realtime, and even accurately track your velocity, so long as there is a clear line of sight to the satellites. If your location is "bouncing back and forth", then you do not have GPS enabled. Period.
I would like to know, once and for all, was HTC lying on their phone specifications in saying that the HD7 has GPS or not?
My old HTC Touch HD had it. Why on earth does this HD7 not seem to have it?
Has anyone here ever actually managed to verify that a true GPS receiver even exists in this phone?

There is a GPS reciever in the phone or it wont be able to pinpoint your exact location in Bing Maps.

I have never had bing maps pinpoint my "exact" location though, only maybe to the nearest 20 metres. And the pointer doesn't seem to move as I move, which suggests to me it isn't using satellites at all...

You seem to be confused. To clear up your misunderstanding, read this:
http://en.wikipedia.org/wiki/Assisted_GPS
FWIW, I use the GPS radio on my daily 6km runs. My old Holux devices (CF-Card, USB external), used to take 30-60 seconds to grab a 3D fix. My HD7 does it in just 15-seconds. If a data connection is available, AGPS will acquire a 'quick fix' first, then based on that position determine which satellites it should look for, elminating the old trial and error method. Hence, a 'true' gps connection is acheived immediately after the AGPS system does it's job.
Bing Maps is just simply a built-in GPS client for the hardware radio and firmware.
To those concerned about data roaming charges, a data connection is not required to use the GPS radio, but is necessary to use downloaded maps, etc. As the newly released Navigon system stores maps on your device (1.6-2.5gb!) it will run independent of a data connection.
Cheers

I understand perfectly what A-GPS is. However I have yet to see my HTC HD7 actually acquire a satellite signal.
Is there anything in the phone that actually indicates when it has acquired a signal from GPS satellites?
What I believe to be the case is that this phone never actually uses GPS signals, at any stage. I believe it simply uses the cellular towers to triangulate your position, and you never get anything more accurate than that.
I would happily be proven wrong. Or if you could show me somewhere on the phone which says "now receiving from (6) satellites" like my old HTC used to do, I will happily stand corrected.
Bing maps has never ever been "GPS accurate" in my experience, and I have had the phone for just under a year now.

What about the Navigon select app that some German carriers implement on their HD7s, isn't that satellite GPS signal ?

i'm using navigon navigator,that show me speed,exat position,and many other info:hd7 HAS A GPS RICEVITOR!!!

I used Bing maps navigation the other day to find a junk yard about 2 hours from where I live and it was pretty accurate. Even merging onto another highway showed the cursor right where I was. After the initial routing pretty sure I was out of signal since I had no service way out in the sticks yet Bing maps never lost the route. I wa pretty satisfied.
But your right real gps shouldn't need a data signal at all like navigon select. Maps are stored locally.

I'm going to back this post up 100% on my end. I stand outside of my building and have NEVER had my bing map... and it shows me 3 or 4 blocks away from my actual location. I've actually had this question sitting on my end for quite some time now.
I, personally, don't believe that the HTC can be used as a true GPS. It just uses the cell towers like mentioned above.
If somebody could actually prove this, other than saying... IT HAS GPS BECAUSE IT SHOWED ME DIRECTIONS AND ACCURATE DIRECTIONS TOO.... Turn by turn directions though Bing is fine.. but it's still not a true GPS location being used.
Would downloading a GPS program like the 35$ garmin one actually give me a different reading on my map? Would it actually work if I have no cellular signal like a true GPS, and work off of a GPS signal?

@NachoNut and @Heofz: Do the apps in the marketplace that provide system information tell you if the phone is using triangulation or actual GPS? You could also try tweeting @windowsphone, @winphonesupport, @attcustomercare, or @htc asking about it. They're generally pretty responsive

I can't verify the exact GPS hardware, but the "system view" app from the WP7 marketplace shows "GPS location" on my HD7 and reads out to the 100th's place in latitude and longitude and ALTITUDE. You would not be able to read altitude via cell tower triangulation.
I think the issue gets confused because many of the location aware programs will use the triangulation method first while waiting for the GPS to get a reading. For instance, in Bing maps, your location is shown in a wide circle but as GPS locks in the circle shrinks down to a much more accurate location.
Even AGPS cannot get down to +/- a few meters without other outside assistance or references though.

download tools for wp7 app from the marketplace. This has a gps reciever app. Put your phone in airplane mode, and then check if you get a location... I'd do it, but my phone is currently updating to mango.

Not entirely sure what this rant is about to be honest. Just because bing maps is sh!t (which surprise surprise we all know...) doesn't mean that the inbuilt GPS receiver in the phone is useless?! Have you tried Gmaps yet?
As an alternative, why not download WinPhone Info for Mango and it will give you your exact location.
I use the GPS functionality quite often for work, because I have to see lots of different customers in London, on foot. Anyone who knows London, knows how narrow the streets are and how tall the buildings are. Worst case scenario for GPS, yet it works every time and it's very quick to find my location. Even though I think the rest of the phone is underwhelming, this is actually one of the features that works fine. If only Bing was up to Google Maps standards!

I'd like to know the best positioning for the handset it's set for 'line of sight view'.
I go cycling round the park often and I must admit it does not seem as accurate as it did with my old HD2. Could it just be down to construction.

It's the rom. I switch to Telstra rom and my gps is working fine now. The gps on tmobile rom never be able to track my location

Mine used GPS as it came from T-Mobile... in Airplane mode it received the location etc,. but maps can't update because they need a data signal to load their data. It does indeed have a TRUE GPS satellite receiver in it.

Shortly after the mango update, using the free GPSInfo app I managed to get it to tell me it had acquired a satellite signal rather than data only. It gave me altitude readings etc as well as accurate speed info.
Hurrah!
Now all I need is software equivalent/better than tomtom and I'll be a very happy bunny

I was using Navigon Select 2.0 / 3.0 on my HD7 on my holiday to Spain during the summer; for a whole two weeks I had the data connection disabled, and there was no phone reception in some of the mountaineous areas, yet the GPS functioned absolutely perfectly, getting the position quickly and accurately. So yeah there is definitely a proper GPS in the HD7.
My own recommendation for navigation on the HD7 (whether you have access to data or not) is Navigon Europe / USA (ie version 4 of Navigon Select). It's a bit pricey but is price-matched with proper navigation apps on iOS and Android. It does all the usual offline navigation that you would expect with proper POIs, rerouting, etc, but if you let it at your data connection it will also retrieve traffic data, Google Local business results, etc. You can also pin destinations to your Start screen (Home, for example). Absolutely brilliant.

pin point location works fine for me on bing... shows my house on arial view... and while on the move bingel and gmaps both work...
i dont understand why ppl are complaning..

Me too
This has a GPS, but it doesn't lock on very well (or sometimes ever) for me. I am using the T-Mobile version so that may be the problem. If you use the GPSInfo app, it will tell you if you are using AGPS or if you have actually acquired satellites. I have been able to acquire satellites a couple of times, but mostly it just sits there on AGPS mode. I was starting to really like this phone, but the GPS thing might just be a deal breaker for me.

No GPS without data.

Hi.
I'm overall satisfied with my Xperia Z1 but there's one problem that I find very annoying.
Whenever I'm travelling and not roaming, the GPS won't work. Why is this? GPS shouldn't need to use regular data.
I use cached maps in Google Maps.
Thanks // Patrik

It do not need network. It can have support via network but is not the main function. If you keep moving the GPS gets even 10 minutes to find the satellite. Turn on GPS, turn on Airmode, go out from building leave the phone for 1o minutes to find the signal.
BTW, the Maps or Navigation in Android working with Network, are you sure you get the right application? Use Offline Navigators.

Something called GPS Assistance Data is downloaded at regular intervals. It contains positioning data for the satellites. If that data is too old, I'm unsure if it's outdated daily or weekly, it will take the phone a long time to get a fix on the satellites.
Download a free app called "GPS Status" to test the behavior. In that app you can also reset GPS and download a fresh Assistance Data set.
Google a bit about A-GPS and you'll find tonnes of info.

Google Maps most of the time use network for your position and when there is no network it just cant get the signals and positions, Tom Tom use GPS only, for example.

Ok. I don't really understand how positioning works just through the internet though. Sure, trianglulation, but that's through the cell receivers which I'm connected to all the time. How can the phone know where I am just by being connected to the internet via WiFi?

I know but actually I know this problem from long time, in fact when you buy or download a Navigation you always have to check if it's working Offline or Online. Difference is that, Offline Navigation use downloaded maps, Online use maps from Network and this make huge difference and when you are without Network it not working. Maybe today is different but I remember it was like that. Download a simply GPS Tester to check if you get the satellite, if it does then is not the problem of you GPS but of the Application. Then I recommend to use the Offline Neavigators for GPS Only.

No, it doesn't explain it and No, there isn't always a problem with GPS. Where did you get that from?

My Z1 has similarly bad GPS lock times but is under 20 seconds with "Use Wi-fi and data network" enabled to provide additional info. Google seems to have something to do to this because to enable the setting you must agree to them stealing further info about your habits.
My 3 year old HTC gets lock in under 20 seconds with no GLONASS and without "Use Wi-fi and data network" enabled.

From services mode delete the assisted gps data and it will download new ones when u a connected to wifi or mobile data...after that even if u are not connected to network u should get a lock pretty faat...but this data expires pretty soon cuz sat positions keep changing...
