15.5 GPS Troubleshooting
Electrical
– Is the transmitter signal of the GPS sensor connected to the receiver pin of the serial
interface of the MSI 60?
– Is the GPS sensor powered up?
– Does the GPS sensor deliver RS232 signal levels?
Interface
– Do the baudrates of the GPS sensor and the device match?
– Is the GPS sensor set up for 8N1 transmission parameters?
– Is the GPS sensor set up for NMEA messages?
– Are the GGA, VTG, RMC messages activated?
– With a correctly wired and powered GPS sensor the changing GPS time information
(gps_sec) can be immediately observed.
GPS sensor start-up
– Does the GPS sensor ‘view’ the sky?
– Did the GPS sensor complete its initial start-up procedure? This may take up to 20
min.
– A correct reception is indicated when ‘gps_fix’ is showing ‘3D Fix’.
