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

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 is the number of satellites that receiver is using in current position solution. Satellites are not used in solution until they get above 7 degrees elevation mask for WAAS/EGNOS, SF1, or SF2 (7 |
degrees for RTK), and satellites are used until they drop below 7 degrees elevation mask for WAAS/EGNOS, SF1, SF2 or RTK. |

GPS Signal Quality shows quality of signals being received from GPS satellites. Unlike GPS Accuracy Indicator, Signal Quality doesn't include |
WAAS/EGNOS, SF1, SF2 or amount of time signal is received. |

|
Differential Signal Quality is the 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. |

Navigation 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 shows the level of differential signal that receiver has received over past 60 minutes. Level |
of signal that was purchased on receiver will determine highest point on bar graph that operator will see. |
