Research on flight attitude tracking technology of fixed wing UAV

Abstract

The motion totally different between Aircrafts fly at high altitude and vehicles drive on road. Aircraft have many flight attitudes such as pitch up and down, roll left or right, and so on. Flight attitudes determine the height and direction of aircraft, but aircraft pilot’s body is also changing with flight attitudes, that means all the senses are unreliable when pilot flight in aircraft. If aircraft turning a small angle and happened serious shaking, pilot can’t adjust the balance and find the horizon immediately, that might cause aircraft do not restores flight attitudes in right position. In the same way, when aircraft night operating over the ocean, both ocean and dark sky has glisten, it is can’t easily to tell ocean from dark sky. that might cause the aircraft accident like errant flight or crashed into ocean, those accidents were frequently happened at beginning of aviation’ growth. Thus, through the tracking of flight attitudes can make sure the aircraft flight in right direction and safety.
