Abstract

The invention discloses a satellite housekeeping simulator and a satellite housekeeping simulation method for development and test of a micro-nano satellite control module. The satellite housekeeping simulator adopts an integrated functional design and a generalized interface design, comprises satellite housekeeping simulator hardware, a command file and a satellite housekeeping simulator application program, wherein the satellite housekeeping simulator hardware is used for running the satellite housekeeping simulator application program and establishing data communication with an external system; the command file is responsible for describing commands, a command sequence, data blocks and a data block sequence used in control module tests; and the satellite housekeeping simulator application program is responsible for driving a board card to operate, reading the command file, processing bus communication data, executing and managing testing process and the like. The satellite housekeeping simulator disclosed by the invention has good flexibility and high universality, can support the control modules (in different development completion degree stages) of the micro-nano satellites of different types to conduct tests, and satisfies the requirements for ''simultaneous design and testing'' of the micro-nano satellite; in addition, the satellite housekeeping simulator has a certain degree of automated testing capability.

Description

technical field [0001] The invention belongs to the technical field of attitude and orbit control of small satellites, and in particular relates to a space simulator and a method for developing and testing micro-nano satellite control modules. Background technique [0002] The satellite control subsystem is responsible for the control of satellite attitude and orbit, and its performance is directly related to whether the satellite can successfully complete the prescribed tasks in orbit and the quality of task completion. In order to ensure the validity and reliability of the satellite control subsystem, it needs to be strictly tested on the ground before the satellite is launched. Ground testing generally includes two stages: sub-system testing and full-star testing. Among them, the sub-system testing stage takes the longest time and exposes the most problems, which is a very critical link. In the subsystem test stage, it is necessary to simulate the satellite satellite ser...
