The Speedometer recently burned out on my old Fiero GT so instead of replacing the dash board I simply downloaded the free GPS Digihud Speedometer to my Android cell phone and it is very accurate! These cell phones don't really use satellites from space,just the nearest cell towers in your current area.so I was wondering if my robot could use this app since the phone even knows compass direction based off the Cell towers and I don't even have a cell plan! Just turn on the GPS function and it works even down in my basement the Microwave cell tower signals are powerful enough to go through walls,floor and ground.Is there already a similar GPS navigating APP in EZ B windows software addons?
Android phones also have electronic magnetic compasses. GPS can only give you direction if you are moving faster than 1kph. Below that, the phone will use its compass.
There are a few Android apps that can stream the sensor data, including GPS data via Udp packets to a listener. DJ wrote an ARC object that can listen to Sensor Stream, a similar app for iPhone, but the message format is different on all of the Android IME apps, so it doesn't work.
Writing a plugin for this is one of the many things on my todo list, but it has been there for about 3 years (was going to use the SDK originally), so I would not hold my breath waiting for it from me.

Later today I'll send you a link to an app that can read all of your sensors to tell you what you have.
Again, the phone can not get directional information, either from GPS or towers unless it is in motion. If it tells you direction when standing still, it has a compass.
This is one of my areas of expertise. I have been studying and teaching GPS for over 20 years.

If you were in the US, I would give you my old HTC OneM8 for your project, but I think the Canada customs charges would be more than it is worth.

I use these apps on my iphone. I find they work good in a car at speed. At lower speed and covering short distances they are off wildly. For instance in my old car at speed it tracks great. I put my iphone on my RC car and it worded so/so unless I ran in a straight line for a long distance. At the low when I go for a walk apps specifically for that blip walking 0 mph to 9 mph.
So I am not sure this has the resolution for bot navigation. Maybe I am wrong.
