Problems solved by technology

Due to the difference in the configuration of each satellite component and the difference in the relationship between the satellite-ground interface, it needs to be dedicated to one satellite or one platform. Therefore, the test systems of each satellite or platform are different and cannot be used universally. It is difficult to build, expand and transplant, and requires Testers adapt to each different test system
With the rapid increase of small satellite research and development tasks, the original test system construction and use mode can no longer meet the test requirements of small satellite multi-satellite parallel test, rapid test and mass production mode

Embodiment Construction

[0018] The ground test principle of the small satellite control system is as follows: figure 1 shown. During ground testing, the on-board Attitude and Orbit Control Computer (AOCC-Attitude and Orbit Control Computer) runs the on-board program, and the ground dynamics simulation computer runs the dynamics simulation program to simulate the space environment and satellite dynamics control laws. In one simulation cycle, AOCC receives the attitude information of the on-board sensor (the attitude information is generated by the excitation signal generated by the uplink sensor signal source module and acts on the on-board sensor), determines the satellite attitude and calculates the control law, and outputs the corresponding The control command is given to the actuator, and the work information isolation and level conversion module of the actuator adjusts the work information of the actuator, and the information collection module of the actuator through the input interface collects ...

Abstract

The invention provides a method for rapidly building mini-satellite control test systems. The testing systems of the different mini-satellite control test systems are rapidly built, easily expanded and easily transplanted according to the different mini-satellite control test systems to achieve the aims of improving the testing quality and shortening the testing time. An uplink sensor signal source module, a downlink executing mechanism working information isolation and level conversion module and a downlink state information and uplink control signal isolation module are built, so that an outward input interface and an outward output interface of a single component are unified, flexible combinations of different components are achieved, expansion and transplanting are easily achieved, and the reuse rate and the universality of a test device hardware module are improved. According to satellite-ground interface relations of the different mini-satellite control systems, connection and allocation of a hardware module input interface and a hardware module output interface are carried out through a satellite-ground interface adapter, the requirement that test system hardware is not changed while satellite and ground test system interfaces are changed is met, and the real universalization and the board-card-level interchangeability are achieved.

Description

technical field [0001] The invention relates to a method for quickly establishing a small satellite control test system, which belongs to the technical field of small satellite test. Background technique [0002] The control system is a closed-loop multi-autonomous control system in the state of space flight. It has different control modes in different stages of satellite missions. Each mode has its own unique combination of measurement components and execution components, as well as different calculation and control modes. control laws. In order to verify the rationality and detailed performance indicators of the system scheme and technical design, it is necessary to create a test environment that constitutes a closed-loop control for it. [0003] The control test system uses on-board components, software, and programs as the objects to be tested, including test equipment hardware, ground dynamics simulation software, and other software. Due to the difference in the confi...
