Method for transporting and managing satellite constellation information

Abstract

The invention discloses a transmission management method for satellite constellation information, which comprises the following steps: (1) a primary satellite is selected; (2) a routing list is generated according to the topology of a constellation network at each time period; (3) for time periods with two or more than two primary satellites, a ground station allocates satellites which the ground station is responsible for, and the monitoring to different satellites is initiated by different ground stations; (4) after measured and controlled areas are allocated, measurement and control modes are selected for each time period of each satellite according to the routing list to generate a measurement and control mode configuration table; (5) remote control information is uploaded; (6) the primary satellite receives the remote control information sent from the ground, interprets an address according to a destination address field, and performs corresponding processing; and secondary satellites receive the remote control information of a local satellite through an inter-satellite link; and (7) telemetry information is downloaded. The method improves the reliability of constellation measurement and control, the timeliness of the constellation measurement and control, and the flexibility of transmission management of constellation information, optimizes communication channels, and simplifies ground operation.

Description

technical field [0001] The invention relates to a satellite constellation information transmission management method, in particular to a measurement and control information transmission management method, which belongs to the field of satellite measurement and control. Background technique [0002] With the rapid development of satellite constellation research based on group collaborative work mode in China, the real-time measurement and control of constellation satellites has become the content of much attention. [0003] Constellations typically consist of multiple satellites working together to achieve greater coverage than a single satellite. In the case of a large number of satellites, there are two problems in the way of establishing a measurement and control link for each transit satellite to realize independent measurement and control: one is that the time interval between a single satellite passing through the measurement and control coverage area twice before and a...

AI Technical Summary

Problems solved by technology

In the case of a large number of satellites, there are two problems in the way of establishing a measurement and control link for each transit satellite to realize independent measurement and control: one is that the time interval between a single satellite passing through the measurement and control coverage area twice before and after is relatively large, and it is impossible to monitor the satellite Realize real-time measurement and control; Second, it takes up a lot of communication channel resources, the measurement and control task is large, the cost is high, and the ground operation is complicated

However, for a large number of constellation satellites, this measurement and control information management mode has considerable limitations

First, only one satellite can be used to exchange measurement and control information, and two or more satellites cannot be used at the same time to complete the measurement and control of all satellites in the constellation system

Second, only the ground measurement and control link established by the transponder can be used to exchange measurement and control information

Third, there is no exchange of measurement and control information between the secondary stars, and only the remote control information of the main star is received

Fourth, the remote control command of the constellation is transmitted in one data block, regardless of the number of satellites, it will increase the congestion of the satellite network

Fifth, the transmission method of inter-satellite measurement and control information does not use the automatic routing search function on the satellite

Sixth, telemetry information needs to be collected on the main star, which not only increases the storage burden of the main star, but also affects the real-time performance of telemetry, and puts forward higher requirements for the transmission code rate of the measurement and control link
