U-blox NMEA GGA parcing problem #681

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.Ublox neo-6m with NMEA output enabled.
2.Configure to send GGA messages
3.

What is the expected output? What do you see instead?
Sometimes the number of sattelites becomes unrealistic - 25, 40 or even more.
Lat = 0 Lon = 0

What version of the product are you using? On what operating system?
APM v2.34

Please provide any additional information below.
I have tried turning off GGA, and everything works fine, except that the number 
of sattelites in view is no longer available.
Probably NMEA version problem. Sometimes GGA is parced correct, sometimes 
wrong. In latest NMEA verions, they have added a field before checksumm.
