[CA] [CA11] AIS no GNSS Position Fix

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Martin,

In order for the AIS650 to acquire a GPS position FIX, not only must it be interfaced to an operational passive GPS antenna, but the AIS650's internal GPS receiver circuitry must also be operational. Should you have located the AIS650's passive GPS antenna affording it an unobstructed view of the skies overhead and should the ProAIS2 software report that the unit was unable to acquire a GNSS FIX, then it would appear that the AIS650's internal GPS receiver has suffered a failure, necessitating that the AIS650 be sent to one of Raymarine’s Product Repair Centers to be bench checked / serviced.
