[CA] [CA11] Axiom 12 GPS speed variations

[dtfeld]

I am at the boat today at the dock. I am in a covered slip, so I do not have a clear view of the sky, so I don’t have great expectations. HDOP varied from 2-8.2 SOG varied from 0 to about .4 knots and position was varying bout +/-75 ft. Accuracy was jumping significantly from about 30ft to 400+. I had 6 green satellites and 1-3 orange. Most were GPS, and a few Glonass. Seemed to have trouble staying locked on satellites even with pretty good signal.

The issue was observed last outing and the SOG was varying +/- 1-1.5 knots at what should have been a fairly steady 20-21 kts Cruise ( calm clear day on inland lake).

I attached video of the behavior...seemed to get worse as time passed.
