MAAT is an open-source MAVLink based Automatic Antenna Tracking system. It read MAVLink messages from the UAV, calculates the direction of the aircraft, and spins the antenna to that direction to maximize the RF signal strength. It can run as a standalone device, or as a repeater between the UAV and the Ground Station. We also add some extra function (e.g. fly mode changing, data logging), hope it can be a lightweight replacement of the ground station in the leisure flights.
The features of MAAT include:
Antenna tracking (in cooperation with APM and wireless data transmission module)
Aircraft status monitoring
MAVLink message relay
Fly mode setup during flying
Data logging (to micro-sd card)
