Universal ground power distribution testing cable system for minisatellites

Abstract

The invention discloses a universal ground power distribution testing cable system for minisatellites. The branch cables and contact distribution among a satellite umbilical cable and a power distribution testing device and an umbilical cable, among a solar cell square matrix simulator, a stabilized-voltage power supply and the umbilical cable and between a satellite equivalent device and a satellite-ground simulation connector assembly, reserves a part of standby contacts, improves the flexible of cable design, improves the universality to the maximum degree, and enlarges the application range. The system can be applied to all minisatellites under the condition that the design rule of a satellite-ground interface is not betrayed, changes a situation that a person needs to design and develop a dedicated satellite-ground power distribution testing cable for each satellite, and greatly saves the manpower, material resources and time cost.

Description

technical field [0001] The invention relates to a general ground power supply and distribution test cable, in particular to a small satellite general ground power supply and distribution test cable system. Background technique [0002] Due to the great differences in ground power supply, key wired commands, and parameter measurement requirements between satellites currently under development and in orbit, and the contact assignment of satellite-ground cables such as plugs and connectors needs to be followed and considered. Principles and factors, so the traditional approach is to design and produce dedicated low-frequency cables for each satellite, but none of them are universal. The design of test cables for satellite-to-ground power supply and distribution is a cumbersome project. While the differentiated design increases the workload of designers, it also greatly increases the waste of resources. With the shortening of the development cycle of small satellites, many test ...

AI Technical Summary

Problems solved by technology

The design of test cables for satellite-to-ground power supply and distribution is a cumbersome project. While the differentiated design increases the workload of designers, it also greatly increases the waste of resources. With the shortening of the development cycle of small satellites, many test cables are still in use. The life span will end with the end of the model test, resulting in a great waste of manpower and material resources
