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.
