Hi there ..
is the gps always on ?
how to power it off ?
if not how does it get power on, on first connect ?
thanks

when the port gets initalised it starts the hardware

I thought that the GPS was always "sort of" on unless the phone was in complete flight mode.

If that were true you would think it would be a fairly serious design flaw.. Battery life, etc.. And since it takes so long to get a sat lock anyway it would be kind of pointless..!!
Everything I've read so far says it is activated only when invoked by an application.

It's possible to always get an approximate fix on your location, but that isn't GPS. That's possible via triangulation from the cell towers. Google Maps does this unless you tell it to use the GPS.
The GPS is only ever turned on when it is used by an application.

Thanks for clarifying that. You're both right, it would be silly to have the GPS constantly activated.

thank you ...

With Airflight Mode ON,it's still possible to use GPS...
Incredible...what a flaw!!!

how to set GPS on when flight mode on?
Hi,
Does anyone help me to set GPS on when flight mode on? If I set flight mode on, then tomtom cannot get GPS signal. Traveling with flight mode on will save lots of power.
Cheers

isn't that irrelevant since the gps doesn't SEND anything?

really if you think about it, the gps hw on th phone only recieves data.
i usually carry with me a gps datalogger that does pretty funny lines when i connect it to google earth after arrriving home from my flights

As others have said - Absolutely not a flaw at all. Indeed a nice feature which was in the TyTnII as well. GPS by its very nature is a reciever only, so nothing is transmitted to interfere with AC avionics.
In answer to the oringinal thread starter .. as far as I can tell the GPS shuts down when no software is polling it. Not sure what the timeout is. Would guess a minute or so.

Really? TomTom 7 says 'GPS disabled because device is in flight mode.....'
Weird.
It shouldnt be disabled anyway as it's just a passive receiver - no transmit therefore no issue with airplanes.

thats my guess also (activated on request)
but i would rather prefer an option that allow-me to turn it off no matter what..
Thank you all for the answers

It's not quite that straightforward as a GPS receiver, like any electrical piece of equipment, has the potential to transmit RF radiation. Of course, whether the level and form of radiated power is sufficient to cause any difficulties with avionics is a different question entirely.
Like all rules of what is, and isn't, allowed onboard aircraft the final decision is down to the airline (which in turn base their decisions on official rules and regulations).
There is a list of airlines which do/don't allow GPS usage onboard here (it also contains an discussion on the issue). Note the caveat that allowed GPS usage is for cruising, not landing/takeoff where the number of critical avionic systems in use (and relied on) is increased.

"Flight Mode - all connections Disabled" is what Tom Tom actually says. It does not say that the GPS is disabled, just the connection.
You can even see this in this screen shot I took a few hours ago. Note the co-ordinates and information displayed. Now if you were to take a look at s34.88499e150.24473 in Google Earth to see where those co ordinates are, you will see that I could not have driven my car there. But I can assure you I was there. Also note the correct UTC time which will only display with the GPS running. There is no way TomTom could have known I was in that location unless it was using the GPS. So TomTom is sort of disabling all connections between itself and the phones GPS. But the GPS is still running.
Further - If you have your Diamond in flight mode - Just fire up the GPSTest application and you will see it has no problem getting a fix. Although it takes the whole screen so I cannot take a screen showing showing flight mode and the fix concurrently.

Fair call - I had never actually got a fix in that situation so I thought the GPS was disabled. Thanks for pointing that out.

The two fat people would sure as hell attenuate the signal. (But perhaps protect the avionics). Fotunately for me I get to sit at the other end.

Is GPS active in airplane mode?

As the title reads, can the GPS be used with the phone turned off?
I am hoping to use it on a flight so I can track my route (for pure curiosity) but if it doesn't work....
doubt it

i know the GPS does not work when phone in airplane mode. perhaps if someone wrote an application that would disable the radio on the phone but keep gps alive. not sure if anyone would do that as i doubt the demand for such product/service/application is fairly minimal at the moment as personally i cant see the point of wanting to track my route (unless i was on ocenic flight 815!) or unless i owned my own private plane, but if i did then i would probably rely on more trustworthy equipment than the gps module on my diamond!

Yes, the GPS component of your phone can work while your phone is off.
Here is the Trick
If you haven't already, create a pin code before enabling your phone.
Path...Settings>Phone>Pin
Once you have created a pin, exist and go to CommManger. Here shut down your phone. Once that is done, turn it back on again. This time your phone will require a pin to turn your phone on. Instead of putting in your pin, hit cancel. Now you are free to use any navigational system without the concern that your phone is on.
Try it!
my phone tells me that without entering the pin i can only dial emergency nrs like 911
so is the radio really off?? because that is wat you want
tried it once on the airplane - still waiting on the runway though - but i got no signal...
Turning the cell radio off should leave GPS on, http://www.modaco.com/content/windows-mobile-news/272846/vario-iii-gps-470-mph/
The point is, because I'm an airplane/flightsim geek, i'm curious about what route the flight takes..
Anyway... conflicting opinions..
And I do think that the radio is still on if you are able to call emergency numbers(i.e. before PIN)
I was thinking, because the gps is integrated into the chipset and not an independent one like SiRFstar, once the phone module is of, so is the gps
The airplane mode does not interfere with workings of the GPS BUT some aircrafts are equipped with a screen that stops the GPS signal from penetrating the plane body. My personal findings are- new Boeings 7 series are equipped with the screen, Airbus A32x is fine.
The new 7 series? All Boeings are 7x7... if you meant the 777
As far as I know, GPS is used from time to time in the cockpit

I used it once with my P3600 and that worked, the problem is that you can use it as long your above ground as soon you will fly over the sea there are no maps, at least not for TomTom.
And another problem is the speed the programm which I used (TomTom ) worked well but the update interval is that big that the nav engine got confused.

What if you use your phone without a SIM card? Never tried it, and it's too late to go outside and try it now lol.
I can confirm that GPS does work in airplane mode.. just checked it

Do I need DATA connection to use built-in GPS?

Hey guys, first of all I love this forum and the people here. It's amazing the kind of apps and roms you guys come up with!
An easy question for most you is, what do I need to take advantage of GPS (if there is one) in XPERIA?
Hi angle180,
You don't have to use a dataconnection for using the GPS.
I use Sygic routeplanner in my car, without dataconnection.
And that worked fine, untill my X1 decided to stop working...
GPS is a simple antenna so the use of it is free.
Now some programs will require money to use.
but for example i use garmin xt for naivigation.
only thing to pay for is the software and any updates for said software.
With all the software making use of the GPS it makes phones with them built in super powerful.
I'm amazed that the use of GPS is free - i'm supprised they dont charge for it because its such a powerful tool!
check here for some more apps to use it (in case you missed the thread)
Thanks guys!
"I'm amazed that the use of GPS is free - i'm supprised they dont charge for it because its such a powerful tool!"
they can't
they can't detect you are using it
it's broadcast like radio your gps device don't send anything it get a "ping", signal with it's own location, from 3-more gps satellites which they keep broadcasting and thats all they do
it calculate where it is from those signals

not entirely true.
example sirius and XM can charge you for the service. same as Dish network and other sat services.
but they charge you based on your box's serial number or smart card accessing the database.
but blah thats another story.
and in my opinion, when they discovered gps they had no clue what they were sitting on. so they made it free.
just like they guy who invinted the hanger. imagine if he / she put a patent on the design.

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.

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.

I was in London last weekend and the GPS was completely useless. I was of course outside and walking around.
I don't see why an offline navigator would make a difference from cached maps in Google Maps. Could you please elaborate your statement?
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...

How did it know?

Hi all.
Aparently Motion Sense does nor work in Mexico because the frequency the solton radar uses is not authorized for civilian use.
Today I took a southbound flight and right about the time we crossed the border (I was tracking the flight on the plane's entertainment system), I got the popup saying that the Motion Sense capabilities got disabled.
My question is, my phone was of course in airplane mode, gps, data and wifi off, so how did it know its postion?

I was just recently investigating about "airplane mode" and couldn't find anything conclusive although there were suggestions that airplane mode might not actually make your phone entirely "invisible" , but rather makes it only act like an advanced DND.
If this is true, and your phone does indeed send and receive *some* sort of pings (I would sepculate GPS to be the most likely culprit if that's teh case), thne that would explain its usefulness in the scenario you described. It also could be a safety feature for users if their geolocation was still tracked in certain situations such as kidnapping.
GPS is a passive system. It never transmits and can fix your position by only receiving satellite broadcasts. If it already has map data, then it can correlate the position fix to a map location. Airplanes only care about transmitting devices, which GPS does not require. So there's no reason for Airplane mode to disable GPS.
Edit: It would make more sense if the Soli system just has a whitelist or blacklist of geofences. When you enter or exit one, it might disable Soli. It doesn't have to be very accurate, just a polygon blob around certain countries.
Aaaaaah, that makes perfect sense. Thank you for your reply.
