My reply was not "unfocused due to lack of information". Again: A-GPS is not improving accuracy. If GPS on a device is not accurate, you can not improve that with software at all. There is no "magic trick" to make the GPS reciever work more accurate and you also can not "calibrate" GPS. A-GPS/A-GNSS only reduces the time to first fix, since it will provide the satellite position data, so the reciever does not have to download this data from the satellites using the slow GPS downlink connection. Also a magnetometer has *nothing* to do with GPS at all. It will only report, to which direction the device is currently oriented. But this has *nothing* to do with your current position. You may need to calibrate a magnetometer from time to time. -- Arno Welzel https://arnowelzel.de
