NavNet vxII GPS data to plotters ?

Postby Christina-Eos » Sun Nov 05, 2017 4:26 pm


I have the following NavNet vxII equipment installed:

BB with a 36 mile radar with a separate 10" display (firmware updated 2017)
GP 1720C 7" display (firmware updated 2017)

The chart plotter displays sometimes see the GPS data and then sometimes they don't ?

If I go to the Menu, System Configuration, System Set Up, Nav Option, GPS Sensor Settings, GPS Status, I get the following information:

Along the top of the page:
current time and date (which looks correct)
DOP --.-
ALT ----- m

Then in the diagram showing GPS satellites I can see 12 satellite and in the vertical box beside that SAT SNR No. 30 40 50 is empty with once in a while a bar showing.

So it looks like the system sees the satellites in the sky but, .... ?

Please help, .....

Thanks, Paul

Good afternoon Paul,

Thank you for your inquiry. Could you please provide a photo of the GPS Satellites in view. It would be best to try and get a couple of photos. Please make sure to capture the GPS Sat view on the display that actually has the GPS plugged into it. If you could provide a photo of that view when GPS is active and present, and a photo when GPS is not working that would help out.

My guess is the GPS is starting to fail or there is a cable issue that has developed over the years. Do you know what port the GPS is plugged into and on which unit?
