As I powered up my Raymarine
E120 system this morning, I received 2 AIS
"No sensor position" and
"No Valid SOG information"
Even after acknowledging, the alarms kept popping back up every couple of minutes or so.
What is strange is that the GPS
information is correct, along with the other data (wind speed and direction, cog, etc..).
Background info: 1) a lot of heavy rain showers in the last 24 hours, although no rain at the time of powering the system
2) Due to windage and heavy backflow in the marina , my boat rolls, pitches and yaws quite a lot in these conditions, possibly throwing off the internal compass
Hoping for the combined enlightenment of the CF community
