Taking into account nonholonomic contraints of SINS output signals in azimuth correction algorithms

  • O. A. Babich


Modern strapdown inertial navigation systems (SINS) usually calculate the course angle of aircraft as a sum of two angles: the azimuth angle of the ‘platform’ and the heading determined by a gyro. The values of each of these two angles depend on the initial conditions of the azimuth channel alignment and the flight path of the aircraft at the previous phases of the flight. The paper studies this ambiguity; a method is proposed to take it into account in the algorithms for correction of the SINS heading channel.
