A satellite telemetry parameter allocation and scheduling method

Abstract

The invention provides a satellite telemetry parameter allocation and scheduling method, including: step 1, the upper computer collects the whole satellite telemetry parameters from the lower computer, and the collection period is equal to the operation cycle of the upper computer; step 2, designs the telemetry frame format, and divides into fixed telemetry areas In the subcontracting telemetry area, the upper computer performs grouping according to the format of the telemetry frame; step 3, design a large table of telemetry data frames, and the upper computer performs grouping and downloading of telemetry data according to the large table of telemetry data frames. The present invention realizes the dynamic scheduling capability of satellite downlink telemetry data through the method of centralized allocation of telemetry parameters of the satellite upper computer, and can conveniently increase the downlink rate of the telemetry parameters of the tested system through the way of uplink injection during the satellite test process, It can more effectively judge the state of the test system, and can focus on downloading different telemetry parameters according to the different stages of the satellite in orbit, and realize the ability to download key telemetry parameters in different working modes.

Description

A satellite telemetry parameter allocation and scheduling method Technical field [0001] The present invention relates to the field of spacecraft, in particular to a satellite telemetry parameter distribution and scheduling method. Background technique Ground station is by receiving the radio frequency signal that satellite sends, and demodulation synchronously goes out telemetry data, by telemetry data Interpreting and obtaining the working status of the satellite in orbit can effectively control it. The satellite is in the development stage on the ground, and the electric measurement at each stage During the test and various tests, it is judged whether the equipment is working normally by observing the telemetry data. When a problem occurs, it usually takes It is necessary to analyze the telemetry data to accurately locate the problem. Therefore, the advantages and disadvantages of the satellite telemetry scheme have a great influence on the development of satellites....
