I am developing a location based application which retrieves GPS locations of the device using Location API framework.
I am testing it on emulator.
In that I am fetching heading from the TCourse object got from TPositionSatelliteInfo object. First time it is giving me value 360. In next subsequent course I am getting values like 334.10001, 329.3999, 343.50000 etc.
So my query is what exactly these values shows and in what reference. Like values are with respect to just previously location or starting location? And also with what reference I mean how I can know the direction? This heading value(angle in degree) is from which direction?
