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 Off-
set value to compensate for the antenna and in-line amplifier delays. Under typical con-
ditions, 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.
