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
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.
