Has anyone experienced an unhealthy GPS signal message in QGC or Mission Planner. I have a gpsstatus 4 and GPS: 3D dgps with a satcount of 12. Any ideas why we are getting the Unhealthy GPS signal? The boat is outside on the cement pad and has a good view of the southern sky. We muted the computer so we would not need to hear the constant message every 30 secs, and the boat operates fine in auto and waypoint missions.
