2.Working Principle
In FPV flight, in order to get a better quality of video signal reception, we wish to use
high-gain antenna. But the high-gain antenna is often accompanied by a narrow effective
angle. MFD AAT is designed to solve the difficulty to maintain directional antenna in the best
angle of reception and transmission during FPV flight.
To form a complete system, you need to mount the TeleFlyOSD module on the plane. The
TeleFlyOSD reads data from the GPS on the plane, encodes and modulates the plane
coordinates and height information and transmits them back via a wireless audio channel
(usually use wireless image transmission audio channel).
The tracker transmits the audio signal received to the AATDriver. The AATDriver
demodulates and decodes the signal to obtain the plane position information. After
comparing with the original coordinates, it gets the current plane azimuth, distance and
height, etc. relative to the tracker. Then the AATDriver transmits the information to the
tracker that drives the internal servo to make the directional antenna aimed at the plane
position.
3. Specifications
With a built-in high quality electrical slip ring, MFD AAT has the unrestrained,
continuous panning capability. There is also a built-in electronic compass which makes it
as a Plug-and-Play system without extra initialization.
