View Full Version : Digital compass

How does a GPSr use digital compass data? Does the digital compass contribute to the nmea data?
The reason I ask is because the pointer in Trimble Geocache Navigator still seams to jump about while stationary on my new Nokia 6210 (with digital compass) the same as on my 6110 (no digital compass).
The digital compass is very obvious with Garmin XT in pedestrian mode. Very impressive.

Depends if the GPS has any averaging, the pointer will jump around less if there is no digital compass or plenty of averaging is happening.

The issue may also be the DC needs to be re-calibrated.
