GPS Accuracy Indicator: GPS Accuracy Indicator is a relative indication of overall differential GPS performance.

Differential Signal Quality: Differential signal quality is strength of StarFire network signal (SF2 or SF1). Normal range is from 5 to 15, but maximum reading on indicator is 10. Numerical value is displayed to right of indicator. Any value above 5 is normal.

PDOP: (Position Dilution Of Precision) is a combination of vertical and horizontal error (or three dimensional). Lower PDOP is better. A value below 2 is considered optimal.

Satellites in Solution: Number of satellites that receiver is using in current position solution. Satellites in solution are not tracked until they get above 5 degrees elevation mask.

Position Mode: Position mode is represented as three different types; No Nav, 2D and 3D. This helps determine if GPS position has been dropped in last 60 minutes.

Differential Mode: This shows level of differential signal that you have been receiving over past 60 minutes. Level of signal that you purchased on your receiver will determine highest point on bar graph that you will see.
