I installed the system 5-6 months ago. The system consists of the NavNet TZtouch2, a PG-500 heading sensor, an FA 50 AIS transceiver and an old FCV 600L color depth sounder which is not interfaced to the network.
Our displayed GPS velocity keeps jumping all over the place even when we are quite stationary in the slip. I've uploaded two videos that show the erratic velocity and the satellite reception respectively.

I am not positive if the problem is new or has existed since the initial installation but I think it is getting worse. No other GPS receivers onboard have issues so it is not an external GPS interference causing the problem.
I'd really appreciate some suggestions for how to track down the source of the problem, maybe a poor connection in the system or maybe noise in the power supplied to the system or maybe a failing component in the system ?
I have turned just about all electrical systems onboard off and the problem remains.
Insights or suggestions ?
TIA !
