Zusammenfassung: | The invention provides an inertial navigation turntable high-fidelity simulation instruction generation method and system, a medium and equipment. The method solves the problem that the semi-physical simulation precision of inertial navigation equipment is reduced due to neglect of earth rotation and motion implication. According to the method, rotary table control attitude calculation and aircraft attitude calculation are independent, the principle that the actual sensitive angular velocity of an inertial navigation gyroscope is consistent relative to a geocentric inertial coordinate system is taken as a principle, the earth rotation angular velocity and the involved angular velocity in the flight process are compensated for the kinetic calculation angular velocity of a simulation model, and then the earth rotation angular velocity is corrected through a simulation test; the inertial navigation gyroscope sensitive rotary table motion angular velocity is obtained, a quaternion differential equation is combine |
