Problems solved by technology

This invention can realize the real-time monitoring and control capability of pico-satellites, but there are also deficiencies, mainly including: the lack of a ground charging management unit for on-board batteries, and the inability to realize the simulation of satellite separation signals, resulting in the lack of equipment for testing links
At the same time, there is no ground rapid test equipment specifically for the general standard cubesat in China.

Abstract

The invention discloses a cubesat universal ground rapid test system, which comprises a satellite power-on management unit, an on-board battery charging management unit, an RS232 interface unit, a solar panel input interface unit, an on-board voltage state indicating unit, an on-board electrical signal indicating unit, a DB37 standard interface and a pin configuration unit. Compared with the priorart, the cubesat universal ground rapid test system has the beneficial effects of: aiming at the ground test requirements of a universal cube micro-nano satellite, integrating satellite separated power-on control, on-board battery charging management, on-board equipment data acquisition, on-board electrical state indication, the solar input interface for test and the like, adopting a standard interface and being connected with a satellite by means of a test umbilical cable, and satisfying rapid test requirements of a cubesat.

Description

technical field [0001] The invention relates to the field of satellite testing, in particular to a generalized ground rapid testing system for cubesats. Background technique [0002] Cube micro-nano-satellite (referred to as "CubeSat") is a kind of micro-satellite with international general standards. The volume of 1U cube star is 10×10×10cm, and it can be expanded to 2U, 3U or even tens of U on this basis. Standardization, modularization, low cost, and rapid integration and deployment are important features of CubeSat. The ground test equipment is an important supporting equipment to meet the rapid integration of CubeSat, which can be used for the startup and shutdown of satellite electrical systems, status monitoring and output of on-board equipment, and almost all ground tests and launch site tests. Therefore, ground test equipment is one of the indispensable and important equipment in the satellite development process. [0003] refer to figure 1 , the Chinese patent ...
