Satellite integrated controller

Abstract

The invention provides a satellite integrated controller. The controller comprises a computer module and an interface module; the computer module integrates an attitude and orbit control computer, a house-keeping computer and a calculation and data processing unit of a lower computer of a power supply controller, and corresponding computer functions are achieved through the computer module uniformly; the interface module is used for providing the interface function needed by communications of the computer module and external devices; the external device comprises one or more of a sun sensor, astar sensor, a magnetometer, a gyroscope, a flywheel, a magnetorquer and the power supply controller. Accordingly, integration design is conducted on an existing satellite platform resource, design of a satellite platform is simplified, and the satellite platform resource is saved.

Description

technical field [0001] The invention relates to the technical field of satellites, in particular to a satellite integrated controller. Background technique [0002] As the core part of the satellite, the satellite platform generally includes seven systems of onboard computer (also known as satellite service or digital control), power supply and distribution, attitude and orbit control, propulsion, measurement and control, thermal control, structure and mechanism. The platform requirements are independently designed, and finally a system solution that meets the platform requirements is realized. In order to improve the reliability of each electronic system of the satellite platform, the design scheme generally adopts single-particle protection technologies such as redundancy design technology and reconstruction technology to avoid the impact of space radiation on the system, and uses derating for selected components. The means of device degradation achieve the purpose of imp...

Problems solved by technology

On the one hand, this kind of design scheme increases the amount of information transmission and protocol complexity between on-board computers, and on the other hand, it wastes resources such as satellite space, weight, and energy.

[0004] Micro-satellites have strict requirements on quality, space, and power consumption. Traditional satellite platform design solutions cannot efficiently meet the needs of micro-satellites

The traditional satellite platform is independently designed and completed by each component system according to the overall requirements, and finally linked together to realize the functions of the satellite platform, resulting in the existence of multiple computers and data processing units on the same satellite platform, which increases the complexity of information between systems on the one hand, and on the other On the one hand, the precious resources of the satellite are wasted
