dc.description.abstract | This paper shows a new fast initial self alignment
algorithm could be applicable to military helicopters with INS(Inertial Navigation System). There are a few critical problems in the navigation system for military helicopters. First, unlike the civil aircraft, the military helicopter could not maintain static state for several tens minutes on the ground in case of urgent need. Second, the sensor noise due to rotor vibration is very severe so that it takes more time to calculate the initial attitude and has more large alignment error. Finally, the soldiers loading and wind buffet effects during the alignment can suddenly change the initial attitude of the helicopter. To provide solution of these critical problems, the navigation grade strapdown IMU(Inertial Measurement Unit) with noise caused by vibration of a rotor is modelled and IIR filter is designed to reject these rotor and undesirable sensor noise. Finally, this paper proposes a new fast initial self alignment algorithm which reduces the alignment convergence time and enhances the alignment accuracy. | en |
