Compass and Accelerometer Calibration

The Archer 2 has a built-in compass and accelerometer.

The compass is used for embossing GPS/GNSS information

on pictures taken with the camera, or embedding GPS/

GNSS information into jpg files. The compass is also used by

the JSNav program. The accelerometer assists the compass

in determining direction, even when the device is not

resting flat. (See Chapter 6, GPS/GNSS, JSNav Application

and Chapter 7, Camera, Geotagging.)
The compass and accelerometer can also be used by other

user applications.
