A-1-2. Configure Update Rate
Alpha supports 1 / 2 / 4 / 5 / 8 / 10 Hz RTK update rate; default is 1Hz. Higher update rate can be
useful for precision guidance applications. Update rate command affects $GGA / $RMC / $VTG / $PSTI
030 messages; the other NMEA sentence is slow changing and remains at 1Hz unaffected by update
rate command.
User can change the update rate from Settings pull-down menu of RTK Viewer, select "Configure
Update Rate" and choose the desired update rate.
