The invention relates to a high-precision combined pose determination method based on genetic optimization REQUEST and GUPF. The invention relates to an inertial / astronomical combined pose determination method based on a star sensor. The inertial measurement information by compensating the gyro output data and attitude calculation get real-time attitude information; secondly using astronomical measurement information, combined with the gyro output data after compensation, through the high precision astronomical attitude information quick access to specific genetic interval optimal REQUEST method based on the use of Genetic Unscented Particle; finally Filter (GUPF) algorithm combines astronomical attitude and attitude information, solve nonlinear and non Gauss noise problems, solve the high precision attitude information, estimation of gyro drift, and feedback correction of attitude and compensate the gyro drift compensation; finally based on astronomical measurement information in real time to eliminate inertial / Celestial Integrated Navigation System with gyroscope On line correction of machine errors, the spacecraft has a long time and high accuracy combined attitude determination.
