Position Dilution of Precision (PDOP) is a unitless measure indicating when the satellite geometry can
provide the most accurate results. When satellites are spread around the sky, the PDOP value is low and
the computed position is more accurate. When satellites are grouped close together, the PDOP is high and
the positions are less accurate. Lower PDOP numbers are optimal, higher numbers are undesirable.
• Correction Frequency
The Correction Frequency indicates the GPS satellite frequency used by the receiver.
Note: The Correction Frequency diagnostic does not show for WAAS connections. Description.
• Correction SNR
If your receiver is using Beacon differential corrections, the frequency and signal to noise ratio (SNR) will
be displayed.
Signal-to-Noise Ratio (SNR) indicates the strength of the differential correction signal in relation to the
amount of background noise that can interfere with signal reception.
• Correction Age
The length of time since the GPS receiver has obtained its last update.
Note: The age of the DGPS corrections (as delivered to the GPS receiver) will vary from one second to
several seconds, depending on the characteristics of the individual satellite signals.
• GPS Speed (mph)
The speed of the vehicle.
• GPS Rate
The update rate from the GPS receiver, shown in Hz.
• GPS Settings
These settings include the following, which are displayed from left to right in the Advanced Tab picture on
the previous page:
- (Left) The protocol being used by the receiver. In the above instance, the receiver is using the TSIP
protocol.
- (Middle) The Baud Rate of the data received. In the above instance, the Baud Rate is 38,400.
- (Right) The data bits, parity, and stop bits of the GPS signal. In the above instance, the data bits are 8,
the parity is 0, and the stop bits are 1. This number is used in error detection, as it determines the
integrity of data received after transmission.

If a TSIP receiver is being used, the TSIP Receiver tab will
display appropriate diagnostics information. The receiver
Product ID, Firmware Version, and Voltage are displayed in
the top frame. The options frame tells you if the Fast Update
Rate or Everest Multipath features are enabled.
• TSIP GPS Receiver information
Displays Product ID, Firmware Version, and Voltage.
• Fast Update Rate
The Fast Update Rate indicates whether your receiver is capable
of outputting an update rate faster than 1 Hz per second.
