Generally, the A07 can be used as an Ntrip modem for external RTK receivers (e.g. for machine control). Due to the integrated processing power an intelligent algorithm supporting domestic data roaming (SIM2X) in Germany and neighbouring countries has been implemented. The RTK corrections are transmitted to the rover receiver via serial port, USB port, or Bluetooth. Additional sensor data (e.g. humidity data) can be transmitted via serial port to the A07 and then send to a server.
