Page 2: System Components
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 operate it correctly. The tracker is a precision mechanical and electronic device. Please read this manual carefully to avoid device damage or body injury. -
Page 3: 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. -

AATDriver: Weight Size 78*44*23mm (Length*Wide*Height) Input voltage 10~13V (12V is suggested) Current consume 100mA Virtual GPS 1200bps Communication *Virtual GPS： AATDriver can virtualize itself as a bluetooth baud rate GPS module. It outputs the location information of the plane with $GPGGA and $GPRMC command. 4. - Page 5 SET button DOWN button Connecting pins Firmware upgrade socket Wires color and function 颜色 名称 功能 Power Power input Black(3 wires) Ground Blue SetHome Set the tracker position Green GPS Data GPS Data Orange GPS Power GPS Power supply(3.3V) * White Audio Out Audio output to transmitter...

- 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 directed to the GPS used. There is a two-way DIP switch on the backside of the TeleFlyOSD module 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 electromagnetic interference and feeder fault due to repeated bending force. Specific mounting methods should be designed according to the actual situation.
- Page 11 3).Preliminary system test Power on the AATDriver with 12V DC. The red LED and yellow LED on the AATDriver will fast blink for several times and then go out. Blinking for 5 times means the data output of the AATDriver is currently in MFD mode and blinking for 2 times means it is in VGPS mode.
- Page 12 5. How to use the AAT Power on all equipments and use the test button on the AAT Driver to check the tracker. Check to ensure the four pointing directions are basically correct and the red RX LED on the AATDriver fast blinks.

6. Advanced Usage Setup and operation of the tracker There are 3 LED indicators and buttons on the right side of the tracker. From left to right, the buttons (LEDs) are: Off-Line (Red) North (Yellow) Cal. (Green) Common functions and operations of the tracker: Function How to operate Remark... - Page 14 default then press and green lights of the tracker blink 5 the North button immediately times at the same time, which within 2 seconds indicates that the tracker resets to the factory default settings and all the calibration data is cleared. CAUTION: If you don’t press North button within 2 seconds after pressing CAL.
- Page 15 After take down the left panel you will see there are 7 soldering pad on the PCB. They are numbered from 1 to 7. A 6 channels tracker has only a 6 pin plug. The Aux Channel 1 maps to PIN#3 of the plug.
- Page 16 Power off and then power on again, AATDriver starts work with the new mode. Every time you power on with holding HOME button, AATDriver will toggle between the two modes Every time power on in a normal state, the yellow and the red lights of AATDriver will blink several times.
- Page 17 MFD protocol contains more information about the plane than VGPS mode. You can use the ground station software provided by MyFlyDream to check the data. Currently it runs on the J2ME platform (need JSR82 support). The android version is also coming soon.
- Page 18 MIDP 2.0, and also support the Bluetooth API (JSR 82) to run it. The FDStaion software can be downloaded from: http://www.myflydream.com/Help1.aspx After installing and running the software, search for the AATDriver and use 1234 as password to establish a connection.

- Page 21 To change options, use the “UP” and “DOWN” buttons to move the marker to the appropriate option and press the “SET” button.
- Page 22 Options menu: Item Remard Press the SET button repeatedly, and VER OFFSE value will vary VER OFFSET between -16 to 15, the whole OSD screen picture moves the corresponding pixels in the vertical direction. Press the SET button repeatedly, and HOR OFFSE value will vary HOR OFFSET between -16 to 15, the whole OSD screen picture moves the corresponding pixels in the horizontal direction.
- Page 23 3). 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 image transmission receiver should be preferably within 1~2V.
