Safran VersaSync - GNSS Receiver Offset

Note: Once a survey has been initiated, the Survey Progress
may not be displayed right away until the receiver has com-
pleted its initialization process.
3.3.3.6 GNSS Receiver Offset
The Offset setting in the GNSS configuration window (INTERFACES > GNSS 0 >
"Edit") allows you to enter an offset to the GNSS time and 1PPS reference in order
to account for antenna cable delays or other latencies (entered and displayed in
nanoseconds).
By setting the correct Offset value, you can offset the system’s on-time point by
the Offset value to compensate for the antenna and in- line amplifier delays.
Under typical conditions, the expected cable and amplifier delays are negligible.
You can calculate the delay based on the manufacture’s specifications.
The offset range is ±½ seconds (i.e. ±500ms, or ±500000000 ns). The default
value is 0nanoseconds, and the resolution is 1 nanosecond.
Configuring a GNSS receiver offset
To configure the GNSS receiver offset:
1. Navigate to Interfaces > References: GNSS Reference
2. Click on the GEAR button next to the GNSS Reference. The GNSS0 win-
dow will open:
3. Locate the Offset field, and enter the desired value.
4. Click Submit.
