1. Product Introduction
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
