Abstract: Space mission with multiple spacecraft formation is an important means to space operation. A new relative navigation algorithm based on stereo vision is developed aiming at high navigation precision requirement of spacecraft formation flying. It uses stereo vision camera attached on the tracking craft as measurement sensor, gets the relative location of target craft in the tracking craft body reference frame with imaging parallax. Relative motion equation is built in inertial frame, and discretized as the state equation of the system. Measurement information of stereo vision is used as measurement value, and the two-step filter relative navigation algorithm based on Kalman filter is designed to estimate relative navigation state in real time, and finally validated by simulation. The simulation results prove this algorithm can meet the relative navigation precision requirements of formation flying.

Abstract: Showing the contradictions in the physics calculations using the equations of the classical theory of gravitation. Alternatively, investigate the physical properties of space objects on the basis of the theory of vortex gravitation, cosmology and cosmogony. The obtained results allow us to evaluate and compare the above objective, physical theories.
