GX450 GPS data lockup


#1

Hello all,
I’ve been experiencing GPS data coordinate lockup on several GX450 modems with AAF 4.8.0 through 4.9.3. The GPS timestamp is updating, but the coordinates remain fixed, even when I know for certain that the location is changing.

Powering down/up or hitting the reset button on the modem corrects the issue. Unfortunately, the problem seems intermittent, so I haven’t been able to replicate the problem in a controlled manner.

I’m streaming the data using NMEA format and a 2sec delay over the DB9 serial.

Any ideas?

Thanks in advance.
