GPS itself does not need a network connection to any server to work. It just needs a signal from a least 4 GPS satellites to calculate a good position fix.
There is also the GPS Almanac, which basically provides future data on where the satellites are expected to be in a given time in the future, usually up to 7 days. This can be used to speed up the ...

This shows the difference between AGPS and GPS. AGPS (Assisted GPS) uses a small amount of mobile data to establish a rough location fix (about 1km-100m accuracy) based on the cell towers near you. This gives a faster initial location fix than just GPS. Since you had roaming disabled, AGPS wasn't available and getting a location fix on just GPS can take a ...

If you enabled "My Location" in Settings > Location & Security > Use wireless networks then your Cell/Wifi and/or GPS data will be sent to Google to triangulate your location if there is an application in the phone that requested for location. Your GPS data may also be sent to Google if you're using Google Latitude, Google Navigation, ...

Walking Navigation was just released today [Sept 9] as an update to Google Maps 4.5.0

I've actually been writing an application that uses GPS, so I can shed some light on this. onik is correct about the AGPS vs GPS. Additionally, though, GPS can be affected by a number of factors which can reduce accuracy or the ability to receive a signal at all:
GPS accuracy is affected by a number
of factors, including satellite
positions, noise ...

If you simply want to find each other, I would use Google Latitude, included in Google Maps, which allows almost live updates (about every five minutes-ish, usually), and gives all the options of Google Maps, including just a few clicks to see a map or use the built in turn by turn Navigation to find each other.
See this similar question for some other ...

GPS - all GPS systems get signals from the satellites. They never send data to the GPS satellites. Your phone would need a much larger antenna to send a signal to them.
Systems like OnStar do send your position back to their servers. Google servers do get your position information so they can calculate directions and pull in the tiles for the map.

No, there is no way to track it without having it configured in some way to connect to a wireless source of data. Without a SIM card you can't do that via a service provider and without having the Google account configured (and thus an authentication token that identifies your phone) you can't do it via WiFi (if you have it turned on).

10 m? You'd be lucky to get that kind of accuracy outdoors.
I'm the developer of Car Dashboard, which is a car home replacement that includes GPS features like speedometer, etc. I have the default minimum GPS accuracy set to 200 m which seems to work pretty good for most users (I also have it adjustable in the settings in case they have issues). On ...

It is actually not the hardware at all.
There is a special file in the android system called gps.conf. This file specifies the GPS servers that the device will use. Each manufacturer wants to use their own special GPS servers instead of the main ones from Google (some have different values for different devices). This means that different devices connect to ...

If you have Froyo or newer (2.2+) you can use SeekDroid (Market link) or for lower versions the same company did Find My Phone (Market link). I've tested only SeekDroid, works great with the web interface, with Find My Phone you only get the GPS coordinates via text message, but you can input the coordinates to Google Maps for example.

data files are usually kept in either /data/data/[packagename]/ or they could be stored on the sdcard.
[packagename] will be something like com.fitnesskeeper.runkeeper.pro. The data file your looking for will probably be in that directory (well, one of the sub-directories any how).
As for if they store the data on the sdcard, most developers do not ...

Per your last comment, you seek Runkeeper Pro (appbrain link) also check out runkeeper.com. I highly recommend it although I'm most likely underestimating it since I just use it for running. It keeps track of your route, time, distance, elevation, calorie burn, etc.
Your hiking, jogging and snowshoeing tours will each be saved to your (shareable) activity ...

The best option is Google's My Tracks
Follow the link and see the features yourself. Everyhing you want is there. And the best part is it's free!!
Hope this helps

There are some solutions available on the playstore. One of them is Traccar (the link belongs to the Android client), which logs to a traccar server you can define. The server software is open source (at least that's what the app description claims), so you can use it on your own server. Written in Java, it should run on most operating systems. For more ...

Well, you can try using avast! Anti Theft, but you must first install avast! Mobile Security because it comes bundled with it. Can be considered as bloat because you don't seem to need the anti-virus features. But avast! Anti Theft is integrated online, which means that you can control your phone using the avast! web site, apart from controlling the phone ...

I strongly recommend you take a look at the lost-phone tag-wiki, which contains a lot of first-aid hints. As you write your SIM is still in the device, there's hope it's also still connected to your Google account and has a network connection -- so hurry up trying solutions like Plan B or Android Lost, which you can then push to your device via Google Play's ...

Try Auto Memory Manager and set your minfree values on the secondary server lower so it has lower chances killing off services. You can also increase the OOM priority of the service to 0 (lower values means less chance of being killed), also part of app.

If you want to see where each of you are, and send messages in case you need help or to see if you're all OK, then Life360 Family Locator is the free way to go.
For security, like locking phone, taking pictures, an all-in-one, then download Android Lost.
If you want to password protect your apps (e.g. connecting 4 dots), then so far I've been using Smart ...

The solution I use is TrekBuddy. I have been using this app for the past 5 years in various platforms from Java to Symbian to Android.
This app can load offline map and show your (GPs) position on it. It can show and record your trail (as GPX) and you can show predefined way points on the map (using GPX again). Being a free project from beginning, it does ...

I actually think your best bet would be to develop the app yourself. I know that you consider it a last resort but you will get exactly the app you want, you can get the app to talk to a web service that writes the data away to a database. Don't forget security, https between the Android devices and t

Each app on Android stores its data on internal storage by default, below the /data/data/<package_name> directory. Due to the sandbox princip, except the app itself and root nobody has access to that if not explicitly defined otherwise by the developer (e.g. Skype currently has a serious security flaw giving everybody read/write access to all its data, ...

GPS is a passive system. There is a constellation of satellites in orbit, with atomic clocks on board, that essentially just shout out their identifications and the time, for anybody who will listen. A GPS receiver listens for the signals and uses the differences in times that it's hearing from the different satellites -- due to speed-of-light delays and ...

I found this from GPS Tracklog. It's from 2005 but my guess is that the technology is roughly (if not exactly) the same.
They come through my roof (plywood and
spanish tiles on top) just fine too,
and they also make it through typical
fiberglass boat construction. Most
materials are not good absorbers of
microwaves, but anything with a high

This is possible with a free app called quick settings. You don't need to root your phone. You should know that if you turn off your data, you won't have real time set to the maps, but you'll still be able to record your gps data. To get around that you can download offline maps app like maveric. Ill add links to this answer later when I'm not driving and ...
