RTK RTCM Injection Using RPi3 or NUC
Raw
rtcm_injection_rpi3.md

You can use a Raspberry Pi 3 or NUC to forward RTCM messages from a ublox base station to a Pixhawk via mavlink, using a combination of mavproxy and socat.

  • Setup RPi3 or NUC with Mavproxy
  • Configure Mavproxy to start the DGPS module
  • Plugin RTK base station to RPi3 usb port (should appear on /dev/ttyACM0 )
  • Conifgure /dev/ttyACM0 to pass raw binary data: stty -F /dev/ttyACM0 57600 raw -echo -echoe -echok -iexten -echoctl -echoke
  • Forward RTCM via UDP using socat: socat UDP-DATAGRAM:127.0.0.1:13320 file:/dev/ttyACM0
