#TN003
#Summary
Why does the differential light flash on
and off?
#Problem
seaPro
incorrectly setup.
Problem
with the transmitted differential signal.
#Solution
If this is occurring at short regular intervals, the most likely cause is that seaPro is decoding two sentences from the GPS, a non-differential enabled
one such as GLL and a differential enabled one such as GGA.
Select
“Setup” from the main menu, then “Nav properties”, and then “NMEA
Rx”.
Select the GPS sentence as “GGA” NMEA sentence
Problem with the transmitted
differential signal
Check
that the GPS is receiving the differential correction.
If using satellite correction service such as WASS / EGNOS the service can be intermittent
