Domain-based microsatellite system

Abstract

The invention discloses a domain-based microsatellite system, which comprises a plurality of functional units arranged in a distributed manner, and is characterized in that the functional units comprise a structural unit, a conduction measurement unit, a comprehensive information unit, a GNC unit, a load unit, a thermal control unit and a power supply unit. According to the design concept based ona functional domain, a miniaturized, standardized and modularized design method is adopted to carry out technical analysis and design optimization of a microsatellite whole-satellite system architecture, and a satellite is divided into different functional modules or functional areas according to task functions and support functions; and physical boundaries of systems / subsystems / components existing in traditional microsatellites are broken through, and the problem that multifunction and high density, as well as functionalization and centralization of the microsatellites are difficult to achieve at the same time is solved.

Description

technical field [0001] The present invention relates to the field of space technology. More specifically, it relates to a domain-based microsatellite system. Background technique [0002] An artificial satellite is an unmanned spacecraft that orbits the earth and is generally composed of a dedicated system and a support system. Dedicated systems are systems directly related to the mission performed by the satellite, also known as the payload. The support system refers to the system that guarantees the normal operation of satellites and special systems in space, also known as the service system, mainly including structural systems, power systems, thermal control systems, attitude control and orbit control systems, radio measurement and control systems, etc. In order to fulfill the goals and needs of users, satellite systems are generally used to carry out comprehensive technologies such as electromagnetic compatibility technology, software engineering, comprehensive testing...

AI Technical Summary

Problems solved by technology

In other words, there are physical boundaries of systems / subsystems / components in traditional microsatellites, which makes it difficult for microsatellites to achieve both multi-function and high density, functionalization and centralization

[0005] Therefore, it is necessary to provide a micro-satellite system that can break through the physical boundaries of systems / subsystems / components in traditional micro-satellites and solve the problems of multi-function and high density, functionalization and centralization of small satellites.
