SN-AAT-PLUS
AutoAntennaTracker
Manual V1.3
SN-AAT-PLUS adopts an efficient video signal encoding algorithm.The sky devices (such as flight
controller) encode GPS and other information into video signals, and then transmit the video to AAT
through VTX to achieve information Encoding -Transmission-Decoding; AAT aims the antenna at the
direction of the aircraft in real-time based on the obtained aircraft position information, and outputs its
information through the MAVLINK, screen, or voice module; At the same time, it supports MAVLINK and
CRSF (ELRS) protocol inputs to achieve digital mode tracking. Compared to the previous generation AAT,
the data recognition rate improves by more than 100% in cases of significant video image interference.

- Page 7 SN-AAT Manual ® RCbro Antenna Installation Please control the weight of the AAT load within 500g (including the antenna). The heavier the weight, the more unstable the center of gravity will be when tracking, and it will affect the service life of the servo! If the antenna size is small and the tracking process is not affected by the AAT shell, you can choose not to use copper pillars.
- Page 8 SN-AAT Manual ® RCbro When using GPS, there is no need to manually configure it, just connect it correctly according to the interface definition. The GPS supports the UBLOX, does not support the NMEA, and also supports the 10th generation UBX module.

- Page 19 SN-AAT Manual ® RCbro ： Will connecting the output video to other devices affect AAT. A：No impact. To connect two screens, you can first connect the video to one of the screens, then connect the video output of this screen to the AAT video input port, and finally connect the other screen through the AAT video output port.
- Page 20 SN-AAT Manual ® RCbro ： Can the sensor module be installed in other locations? A：Yes, just ensure that the installation direction is correct. The installation direction is limited to 4 types of illustrations, and the specific location is not limited to the illustrations provided in the manual. It is recommended to keep the installation position as far as possible from magnetic interference sources.
