The built-in GNSS receiver is connected to COM 3 and works with 9600baud 8,N,1
The model is a uBlox Neo M8 that can use GPS, Glonass, and Gallileo satellites.
The GNSS receiver offers the standard NMEA0183 protocol.
Example log record: $GNRMC,162614,A,5230.5900,N,01322.3900,E,10.0,90.0,131006,1.2,E,A*13
Note that many applications cannot yet process the new general protocol prefix ($GN**). These applications only process the GPS-specific protocol prefix ($GP**). In this case, the software manufacturer should be requested to update the software.
The difference lies in the fact that with the generic protocol prefix, all available satellite systems can be used simultaneously. This leads to more accuracy position determination.
When using applications for which no update is available, the uBlox Neo M8 can be switched to pure GPS mode. The instruction manual for this can be found here.
