摘要
The invention provides an autonomous navigation method of Mars probe. The method comprises the following steps: according to the position relationship of the probe in the solar system, selecting the sun, the earth and the sun, Mars as the observed objects, acquiring the angle information, and establishing the position, velocity and other navigation parameters with the extended Kalman filter (EKF). The invention has the advantages of simple principle and low system resource requirements; it is a new method of autonomous celestial navigation of the Mars probe. The method expands the spacecraft navigation means, improves the navigation ability, and can be directly applied to the future autonomous navigation mission of Mars exploration in China; therefore, it has a wide range of applications in the field of deep space exploration.
