Based on the theory of Kalman filter and the development of satellite attitude determination technology, the application of Kalman filter in the combined orbit determination of stationary orbit three-axis stabilized satellite infrared earth sensor and radio frequency sensor is studied. Attitude measurement model of the geostationary orbit of a geostationary orbit with three-axis stabilized satellite and the combined attitude measurement of the infrared-radio frequency sensor are set up. For this model, the attitude estimation is carried out by using the extended Kalman filter, and the computer simulation is carried out. The filtering method is applied to the validity and superiority of the combined attitude determination of stationary earth-orbiting satellite with three-axis stabilized earth-sensing infrared sensors and radio frequency sensors.
