MFD Crossbow AAT is a device on the ground to trace your plane's position and to keep point antennas to the plane to get a better range/signal.

Compatible with MFD Crosshair/MFD AP or other any system that supports Mavlink protocol.

Crossbow AAT is designed for use with unmanned aerial vehicle (UAV) on-board antenna system. Its purpose and objective is to point the antenna precisely in the current direction of the aircraft thus allowing the video receiver to pick up the strongest signal possible at given distance and other factors. 

In order to obtain better signal reception quality, it is advised to use high-gain receiving antennas. High-gain antennas are known for very narrow angles of effective reception. For its successful operation, Crossbow AAT requires the flight data such as latitude and longitude of the tracked target (UAV) at every given moment, as well as its altitude. This is achieved by the following: 

1. Transmitting information of the tracked target over a wireless analog video link from the UAV to the ground station. For that, the UAV must be equipped either by a MFD Auto Pilot, or a MFD Crosshair Auto Pilot,  or in case a third party AP is used with a MFD TeleFlyTiny tracking module.

ATTENTION: Using TeleFlyTiny module is possible with many third party flight controllers. MFD does not guarantee that it works with any particular make or model of the autopilot, nor that it will continue to work with any third party autopilot after its firmware or software is updated.

2. Transmitting information of the tracked target over a wireless High Definition video link from the UAV to the ground station. For that, the UAV must be equipped either by a MFD Auto Pilot, or a MFD Crosshair Auto Pilot, or a MAVLink-compatible Auto Pilot, or in case a third party AP is used, an MFD TeleFlyTiny tracking module. The signal containing encoded tracking data from the TeleFlyTiny module on the aircraft will be transmitted to the Crossbow AAT through the serial port . 

3. Transmitting information of the tracked target over a wireless digital data link from the UAV to the ground station. MAVLink protocol allows to transmit the information from the UAV through the digital radio link. If the on-board system already includes the digital radio, and the flight controller that supports MAVLink protocol, Crossbow AAT will be able to receive all flight information necessary to track the UAV through the shared TXD line of the digital radio station.
