Abstract: The main function of the power supply and distribution test system is providing power for the spacecraft, sending cable instructions to the spacecraft, and receiving/disposing the cable telemetry signals downlink of the spacecraft, during the whole process of spacecraft system test. The mainstream power supply and distribution test systems are custom-made, which leads to higher R & D cost, longer development cycle and lower reliability. Universal power supply and distribution test system based on host bus and board realize the finalization and the batch production. It solves the problem of different spacecraft′s interface definition, and reduces the R&D cost, shorten the development cycle and improve the reliability of the product. At present, this system has been successfully applied to the testing of several spacecraft. With the continuous enrichment of the type spectrum and the deep application of the spacecraft model, it will have a wider application prospect in the future.
