1. Operating principle
Attitude Flight Stabilization System (AFSS)
DOS module
DOS is an inertial attitude measurement instrument. Now version V1.1 used for automated stabilization of
fixed wing model aircrafts,but after upgrade firmware can be used for other aircraft and equipment control (For
more details of DOS,please refer to the latest firmware and instrctions)
DOS has integrated three-axis gyro ,three-axis accelerometer,three axis magnetometer and barometric
pressure sensor. DOS can accurately measuring flight attitude, the earth azimuth and through the barometer to
measure relative altitude. Through the sensor measurement data combined with attitude control can realize
the Stabilized Mode, 3D Mode, Return To Launch Mode, Fixed altitude and Heading lock flight Mode, Auto
Circling Mode and so on.
GPS module
GPS module enables the DOS to calculate the flight course and exact location of the aircraft. DOS has
three navigation mode :Return To Launch, Auto Circling and Heading lock,You can activate any of navigation
modes after connecting GPS.
Altitude control
DOS use the barometer to measure relative height, through the elevator servo and throttle control to
realize the flying altitude control.
Heading control
Without GPS module,DOS through the three axis magnetometer to measure the heading angle,use the
aileron servo and rudder servo to control flying heading. But will be affected by the wind then deviate from the
original route.
