Embodiment Construction

[0061] The present invention will be further elaborated below in conjunction with embodiment.

[0062] (1) Mars EDL process mathematical simulation master control subsystem completes system initialization and working condition setting

[0063] The main control subsystem of the simulation obtains the initialization parameters such as the simulation stage, the initial time of the simulation, the initial position of the entry cabin, the speed, and the attitude by reading the configuration file, completes the setting of the simulation working conditions, and sends the initial state parameters to the EDL process environment simulation subsystem, GNC simulation subsystem, entry cabin simulation subsystem, Mars EDL process visualization simulation subsystem, each subsystem receives initial state parameters for system initialization.

[0064] (2) The EDL process environment simulation subsystem receives the simulation time, entry cabin position, velocity and attitude information sent ...

Abstract

The invention relates to a Mars EDL whole process autonomous GNC mathematical simulation verification system. The system mainly comprises an EDL environment simulation subsystem, an entry cabin simulation subsystem (including an EDL process entry cabin dynamics high-precision simulator and an EDL process navigation image high-precision simulator), a Mars EDL process mathematical simulation master control subsystem, a Mars EDL process visual simulation subsystem, a GNC simulation subsystem and corresponding interfaces. The mathematical simulation system can comprehensively, systematically, continuously, fully and conveniently verify the GNC scheme and algorithm of the whole flight process of the Mars EDL, the autonomous management technology, the cooperative work with the ground, the flight control support and the simulation capability.

Description

technical field [0001] The invention relates to an autonomous GNC mathematical simulation verification system for the whole process of Mars EDL, and belongs to the technical field of spacecraft guidance, navigation and control. Background technique [0002] The flight environment of the EDL process of the Mars entry module is brand new, and the mission has new features. The mathematical simulation system that has been established in the lunar exploration project can only meet the mission needs of the probe in the earth-moon environment, and cannot meet the Mars entry and landing. task requirements. Therefore, it is necessary to build an autonomous GNC mathematical simulation verification system for the entire process of Mars EDL, realize the digitization and visualization of the simulation system, and facilitate the GNC program designers to modify, adjust and verify the program, key technologies, and algorithms. [0003] The Mars EDL full-process autonomous GNC mathematical...
