Abstract

The invention provides a method and a system for satellite telemetry speed increasing and load data fusion. A measurement and control function and a data transmission function of a microsatellite are integrally designed, and the measurement and control function and the data transmission function are realized in a measurement and control mode and a data transmission mode respectively; in the measurement and control mode, a USB (universal serial bus) measurement and control system is adopted to download telemetry data; in the data transmission mode, acquired effective load data and the telemetry data are packaged, mixed and downloaded, and then the load data and the telemetry data are analyzed on the ground through a virtual channel identification in a classified manner. According to the method and the system for satellite telemetry speed increasing and load data fusion, measurement and control data and data transmission data are effectively fused, the ratio of the measurement and control data to the data transmission data can be flexibly adjusted, and the limit rate of measurement and control data transmission is greatly increased; redundancy of on-board equipment is effectively reduced, allocation of on-board resources is reasonably optimized, the utilization rate of space is remarkably increased, power consumption is remarkably reduced, and besides, the current condition of shortage of frequency resources is relieved.

Description

technical field [0001] The invention relates to the technical field of satellites, in particular to a method and system for micro-satellite telemetry acceleration and load data fusion. Background technique [0002] The successful launch of the Soviet Union's first artificial earth satellite in 1957 marked the birth of aerospace technology. With the rapid development of aerospace technology, spacecraft such as artificial satellites, space stations, and space shuttles have been put into use one after another. However, huge expenses and expensive costs have always restricted the development of aerospace technology. After the end of the Cold War, aerospace science and technology gradually shifted from military application to economic construction, and commercial operations prompted aerospace science and technology to reduce costs and improve efficiency. In this context, on the basis of the rapid development of science and technology, micro-satellites have been developed rapidl...
