specific Embodiment approach 1

[0022] Specific implementation mode one: the following combination figure 1 and figure 2 This embodiment will be specifically described. A three-axis air-floating platform guidance method for verifying satellite formation, said method is based on a simulation platform including three three-axis air-floating platforms, respectively using three three-axis air-floating platforms as three simulated satellites, the simulation platform The console controls the movement of the three-axis air-floor platform, and the simulation platform is used to verify the guidance method of the three-axis air-floor platform of the satellite formation:

[0023] Step 1. Set the three simulated satellites as the main satellite, the first slave satellite and the second slave satellite respectively, and determine the movement mode of each simulated satellite;

[0024] Step 2. According to the motion pattern of each simulated satellite, the console pre-sets the motion trajectory parameters of each simu...

[0036] Specific embodiment two: This embodiment is a further limitation of the three-axis air bearing platform guidance method for verifying satellite formation described in specific embodiment one. In step one, the movement patterns of each simulated satellite described in detail It means: the master star rotates at the set position, the first slave star and the second slave star take the position of the master star as the center, and fly in a counterclockwise movement mode.

[0037] According to the mission requirements and implementation methods of formation flight, there are many models of satellite formation, and the leader-follower model is adopted in this embodiment. In formation flight missions, one simulated satellite is established as the master star, and the rest of the simulated satellites are set as slave stars.

Abstract

The invention relates to a three-axis air-bearing table guide method for verifying a satellite formation, which solves the problem of complex coordination among multiple analogue satellites. The guide method is implemented on the basis of a simulation platform having three three-axis air-bearing tables and comprises: 1, determining the functions and motion modes of the analogue satellites; 2, planning the motion trails of the analogue satellites; 3, measuring the data of the analogue satellites in real time and guiding a first following satellite and a second following satellite respectively;3.1, determining the motion destinations of the following satellites to be guided; 3.2, calculating the distances between the following satellites to be guided and current motion destinations in realtime; 3.3, judging if the distances are smaller than offset values allowed by a system; 3.4 judging if the flight task is finished; 3.5, adjusting the motion directions of the following satellites tobe guided; and 3.6, determining next motion destinations of the satellites to be guided. The method realizes the three-axis air-bearing table guidance of the satellite formation and is applicable in control of the satellite formation.

Description

technical field [0001] The invention relates to the field of aerospace measurement and control, in particular to a guidance method for a three-axis air bearing platform for verifying satellite formation. Background technique [0002] The full physical simulation of the satellite control system is a unique simulation method in the process of developing satellite control. It uses a three-axis air-floating turntable as a motion simulator, also known as air-floating table simulation. The full physical simulation of the satellite control system uses a three-axis air-floor platform to simulate the satellite body as the control object, and the control system uses the satellite control system for simulation. When a space vehicle performs a full-physics simulation, it is necessary to simulate important space environments such as weightlessness or no resistance on the ground. Air-floor table simulation is an ideal method, which can simulate this space environment well and is easy to r...
