Modification of Non-Linear Kalman Filter in Correction Scheme of Navigational Systems of Carrier-Based Aircraft

A scheme for correcting the navigational information of an aircraft during the maneuvering of the aircraft and landing on a moving aircraft carrier is considered. The effective completion of complex maneuvers requires highly accurate navigation information about the position of the aircraft. Navigation information comes from the inertial navigation systems of the aircraft and the aircraft carrier, the global positioning system and other auxiliary systems. The processing of the signals of navigation systems is carried out using the estimation algorithm. As an estimation algorithm, it is proposed to use a non-linear Kalman filter. To obtain high-precision navigation information, it is necessary to estimate and compensate the errors of navigation systems as accurately as possible. Therefore, the organization algorithm is also integraded in the non-linear Kalman filter, which makes it possible to construct an error model of an inertial system in flight. The efficiency of the developed modification of the Kalman filter is confirmed by the simulation results with the C060K system.
