A measurement and control method and system for a satellite entering orbit

Abstract

The invention discloses a measurement and control method and system for a satellite orbiting section, and relates to the technical field of satellite measurement and control. The method includes the steps of: establishing uplink and downlink dual communication links between the last stage of a carrier rocket and a user satellite; establishing a relay satellite system The space-based TT&C forward and return links between the carrier rocket and the last stage; through the downlink communication link and the space-based TT&C return link, the satellite telemetry signal sent by the user satellite is sent to the relay satellite system; through the space-based The measurement and control forward link and uplink communication link send the satellite remote control signal sent by the relay satellite system to the user satellite. The measurement and control method of the present invention realizes the telemetry and remote control of the orbiting section of the user star by the relay satellite system by establishing the uplink and downlink dual communication links between the last stage of the carrier rocket and the user star; due to the distance between the user star and the last stage of the carrier rocket It is relatively close, so the requirements for communication antenna indicators are relatively low, and the engineering implementation is relatively simple, which can effectively guarantee the stability of the communication link and realize real-time information interaction.

Description

technical field [0001] The invention relates to the technical field of satellite measurement and control, in particular to a measurement and control method and system for a satellite entering orbit. Background technique [0002] With the rapid development of commercial aerospace, the demand for satellite launch and networking is becoming more and more urgent. When a launch vehicle is used to send a satellite into space, after the satellite and the rocket are separated, the key parameters of the satellite’s initial orbital segment need to be transmitted back to the domestic satellite measurement and control center in real time to obtain the status of the satellite’s orbital status in a timely manner and provide technical support for ground measurement and control command and decision-making. [0003] The existing telemetry information of the initial orbital stage of satellites is generally received by ground measurement and control stations or survey ships, which takes a long...

AI Technical Summary

Problems solved by technology

However, due to the long distance between the user satellite and the relay satellite, the attitude of the satellite changes greatly during the initial orbit, and the requirements for the transmit power and beam bandwidth of the user satellite antenna are relatively high. There are certain difficulties, and the stability of the communication link between the relay satellite and the user satellite is difficult to be guaranteed
