Abstract

The invention discloses an autonomous global navigation chart (GNC) simulation test system based on optical and inertial combined measurement. The autonomous GNC simulation test system comprises an integrated sensor, a dynamic celestial body and fixed star simulator, a GNC module, a dynamics simulation and environmental simulation module, a radio velocity measurement and ranging simulator, a simulation master control module and a three-axis turntable. The integrated sensor is introduced into the simulation test system, the attitude motion of a spacecraft is realized by employing the three-axis turntable, the dynamic characteristics and spatial environmental disturbance of a deep space spacecraft are simulated by employing the dynamics simulation and environmental simulation module, and the dynamics and external environmental characteristics of the deep space spacecraft are really and reliably simulated.

Description

technical field [0001] The invention relates to an autonomous GNC simulation test system based on combined optical and inertial measurement, and belongs to the field of physical simulation of autonomous navigation and control of deep space spacecraft. Background technique [0002] At present, deep space autonomous navigation is mainly realized by means of astronomical navigation. The basic principle is to estimate the position and velocity information of deep space spacecraft through calculation based on optical imaging of navigation celestial bodies. Because celestial navigation relies solely on angle information relative to celestial bodies, the positioning accuracy is low and it is difficult to meet the needs of the development of deep space exploration. [0003] Optical and inertial combined measurement introduces inertial devices based on traditional optical sensors, which can not only measure the position information of the spacecraft but also the attitude information ...
