Data Logs tab (StarFire 3000 and 6000 Receivers)

Data Logs tab has graphed global navigation satellite system (GNSS) data, logged over the previous 60 minutes.

PDOP (Position Dilution of Precision)

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

Satellites Used

Satellites Used is the number of satellites the receiver uses in the current position solution. Satellites are not used in solution until they get above 5 degrees elevation mask. 

Navigation Mode

Navigation Mode is represented as three different types: No Nav, 2D, and 3D. Navigation Mode determines if GPS position has been dropped in last 60 minutes.

Differential Mode

Differential Mode shows the level of differential signal that receiver has received over past 60 minutes. Level of signal purchased on receiver determines highest point on bar graph.

SF Signal Quality

SF Signal Quality is the strength of StarFire network signal. 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.

GPS Accuracy

GPS Accuracy is a relative indication of overall differential GNSS performance.

High AGC (StarFire 6000 only)

High automatic gain control (AGC) is a voltage-controlled amplifier that amplifies or lowers the volume of the received signal for high-band frequencies.

Low AGC (StarFire 6000 only)

Low automatic gain control (AGC) is a voltage-controlled amplifier that amplifies or lowers the volume of the received signal for low-band frequencies.
