    Notes Thank you for purchasing the MyFlyDream Automatic Antenna Tracker (hereinafter referred to as MFD AAT). Please follow this manual to get familiar with the tracker and to operate it correctly.  The tracker is a precision mechanical and electronic device. Please read this manual carefully to avoid damaging the device or hurting yourself and others.

  • Page 3: Working Principle

    But any high-gain antenna is accompanied by a narrow effective angle. MFD AAT is designed to solve the difficulty to keep the directional antenna pointed at the target to ensure the best possible reception and transmission during FPV flight.

  • Page 8  Connection Diagram B (share GPS with other OSD)
  • Page 9  Selecting appropriate baudrate for TeleFlyOSD Since the output data rate of different GPS may be different, it is necessary to set the baudrate of the TeleFlyOSD communication port to match the GPS used. There is a two-way DIP switch on the backside of the TeleFlyOSD module which is used to select baudrates: The arrow-indicated DIP switch in the figure has an ON mark above.
  • Page 10 2). Mounting tracker and AATDriver Please mount the antenna on the antenna handler of the tracker firmly. The image transmission receiver is suggested to be mounted on the antenna handler to avoid interference. Antenna cables tend to be stiff, continual bending due to the electronmagnetic movement of the tracker might damage it.

  • Page 24 2). Q: How to make the data downlink more reliable? MFD AAT uses the audio channels to transmit data. A clean noise-free audio channel with appropriate level can make the data transmission more reliable. It is suggested the peak-to-peak value of audio output level of the video transmission receiver should be preferably within 0.8~2V.
  • Page 25  Especially the lawmate 1.2G 100mw VTX has audio problem. It is not able to transmit the audio signal clearly. User need to solder 22~45pf capacitor to fix this issue. the added capacitor should be connected in parallel with the green component beside the red arrow, as the below picture shown.
