[LW11] GPS Malfunction
Need help identifying solution.
System data alarm - POSITION FIX LOST
This message comes up approximately every 10 minutes and then returns to normal. GPS data screen shows no satellites when alarm sounds
Advise procedure or part number for solution.

Equipment Type - E80
S/N E02011 0670363
Software V5.69
Prwoduct ID D598

Dear Louise
Not sure if it's a NMEA or Seatalk connection. But I believe the part number for the GPS is e32042 serial number 0474420. The green light on the top of the unit will turn red when the signal lost alarm goes on. Can you help with a replacement part number thanks

Dear frank,

Thank you for the response.

The issue is more than likely to be a fault with the GPS antenna rather than the chartplotter.

What manufacturer is the GPS antenna?
Is it connected on NMEA or seatalk?
Have you checked the cabling for any loose connections or corrosion?

Many Thanks
Louise

Hi Louise
I do not know if the GPS is hooked up to NMEA or seatalk. I did check most of the wiring and it looks okay

I tracked down the GPS location. The green light on the GPS turns to red and my chart plotter indicates lost signal. I opened up the GPS and found part number e32042. Number below it might be the serial number 0474420
Can you advise the replacement part number?
Will it be a direct replacement? Plug-and-play?

Thanks for your help
Regards
Frank

Dear frank,

The replacement GPS antenna would be the RS150, part number E70310. As this is a STng GPS, you will need the ST1 to STng convertor to integrate it with your ST1 system, the part number is E22158.

Many Thanks
Louise
