Payload management system and method for satellite

Abstract

A satellite effective load management system and management method, the system comprises a load distributor, a storage module, a signal transformation processing module, a data multiple connection module and a center processor module, the modularization, integration, standardization effective load management system design conception provided by the invention integrates the data transmission, telemetering measurement remote control, power supply management to be centralized, meanwhile the standard, configurable effective load interface can be designed, so that the resource configuration and the interface configuration of the system are fixed and uniformed, the matching performance problem of effective load managing each task can be effectively solved, the good software and hardware platforms can be provided for time sequence, information and safety management of effective load management, thereby improving the effective load management design level and reducing the complicated degree, corresponding weight and power consumption and so on of the effective load management system, certain basis can be established for improving the whole star performance.

Description

technical field [0001] The invention relates to a new type of payload management system for small satellites, especially for the payload management of small satellites integrating multiple different types of payload equipment; the invention can be used as payload management of small satellites for space electromagnetic detection and space environment monitoring , It is also suitable for payload management of other general remote sensing and reconnaissance satellites. Background technique [0002] At present, the management and data transmission of small satellite payload equipment are completed separately through the power supply subsystem, star service subsystem and data transmission subsystem, among which the power supply subsystem provides power supply for payload equipment, especially the demand for special power supply; star service The subsystem is responsible for the control, management and communication of payload equipment; the data transmission subsystem is respons...

Problems solved by technology

[0002] At present, the management and data transmission of small satellite payload equipment are completed separately through the power supply subsystem, star service subsystem and data transmission subsystem, among which the power supply subsystem provides power supply for payload equipment, especially the demand for special power supply; star service The subsystem is responsible for the control, management and communication of payload equipment; the data transmission subsystem is responsible for the collection, storage and downloading of scientific detection data of various payload equipment; usually a satellite has less payload equipment (1 to 2 ), various interface forms, data communication forms and other designs are unified and easy to manage; with the implementation of Seismic Electromagnetic Star and Kuafu Project, the satellite platform must manage multiple payload devices at the same time. These payload devices are characterized by functions, The interfaces are different, and most of the payload equipment adopts foreign products, and the various requirements for the platform are also different. It is difficult to use the previous method to propose a unified interface design requirement for the payload equipment for management. At the same time, the current payload management It is managed separately by three sub-systems on the star, and the technical complexity, equipment configuration complexity, and information exchange complexity are relatively large, and it does not make use of the unified management of the entire star and the reasonable allocation of resources. The above are the shortcomings of the current payload management method.
