A self-test system and method for spaceborne measurement and control transponder based on lower computer

Abstract

The invention relates to a spaceborne measurement and control transponder self-testing system and method based on a lower computer, and aims to overcome disadvantages in the prior art, develop the self-detection and self-testing functions of a spaceborne measurement and control transponder, and transplant a part of ground test tasks onto a satellite, so that intelligent and batch production requirements of satellite test tasks can be rapidly responded. On the basis of the existing testing system and method and experiences, a build-in test BIT technology is introduced in single machine design of the spaceborne measurement and control transponder; therefore, due to software function configuration, after receiving a ground uplink self-testing instruction, the measurement and control transponder monitors and interprets related telemetry parameters, obtains and analyzes the main function and the internal working state of the core module of the measurement and control transponder autonomously and rapidly, and completes telemetry downloading of a self-testing result; and thus, the spaceborne measurement and control transponder has a module self-testing function. By means of the spacebornemeasurement and control transponder self-testing system and method based on the lower computer disclosed by the invention, the comprehensive testing efficiency and the automation degree of the satellite are improved; furthermore, the original normal working mode is not influenced; and the spaceborne measurement and control transponder self-testing method is high in universality and easy to expand, and applied to other single machine equipment on the satellite.

Description

technical field [0001] The invention relates to a satellite measurement and control transponder self-test system and method, in particular to a satellite measurement and control transponder self-test system and method based on a lower computer, belonging to the satellite measurement and control technical field. Background technique [0002] The rapid response satellite platform is a new generation of small satellite platform proposed to adapt to the future rapid response satellite application requirements and technological development trends. It can be launched vertically and quickly used in orbit. [0003] Compared with the traditional small satellite system, the rapid response satellite system highlights the technical characteristics of intelligence, rapidity, mass production, and convenient operation. On the other hand, with the increase of the complexity of the satellite system, the workload of satellite testing has increased sharply, and the resources such as test site...

AI Technical Summary

Problems solved by technology

On the other hand, with the increase of the complexity of the satellite system, the workload of satellite testing has increased sharply, and the resources such as test sites and test equipment for model testing are very limited. One of the main contradictions in the development process

[0004] The traditional test uses the uplink remote control and downlink telemetry links as the test loop, and uses the simple test mode of command plus telemetry stimulus feedback, which makes it difficult to obtain test parameters inside the satellite

The current satellite comprehensive test process relies heavily on satellite-ground information flow resources, while satellite-ground information flow resources are limited by satellite-ground measurement and control links, and the data rate is low. There are problems that need to be solved urgently, which leads to the low efficiency and automation of the whole satellite comprehensive test. In order to meet the test needs of rapid response satellites
