Ground monitoring system for monitoring operating state of satellite

Abstract

The application provides a ground monitoring system for monitoring the running state of a satellite, which comprises a simulation part, a correction part and a monitoring part. The simulation part isused for simulating and calculating the satellite orbit, illumination condition, energy condition, attitude adjustment, measurement and control link and / or thermal control status of the satellite in the future time. The correction part is used for correcting the simulation data and the simulation model in the simulation part based on the real satellite data. The monitoring part is used for receiving the satellite simulation state data transmitted by the simulation part and the satellite real state data transmitted by the correction part, and determining whether the satellite simulation state data or the satellite real state data is in a set normal range. When the ground monitoring system is unable to receive the real state information of the satellite, the satellite state is estimated andcalculated by the simulation method, and the real-time monitoring and management capability for the entire operation cycle of the satellite is improved.

Description

technical field [0001] The present application relates to the technical field of satellite simulation, in particular to a ground monitoring system for monitoring the operation status of satellites. Background technique [0002] Due to the high cost of satellites, it is necessary to pay attention to the operating status of satellites at all times to ensure the normal operation of satellites and quickly handle faults. The satellite and the ground use the ground measurement and control station to download the satellite telemetry status and upload the satellite control command. When the ground receiving station cannot receive the signal or the ground station does not have sufficient resources to communicate with the satellite, the status of the satellite is unknown, which makes the operation of the satellite face more risks, especially when the satellite is in a fault state, it cannot be found in time. [0003] When the ground does not meet the receiving conditions, the method ...

AI Technical Summary

Problems solved by technology

This method can monitor the operating status of the satellite's entire operating cycle to a certain extent, but it also faces the following problems: 1. When the satellite breaks down (such as energy shortage, orbital deviation, etc.) before establishing communication with the ground station, it cannot be found in time. Faults are only discovered during communication, and the faults cannot be dealt with in time, especially for satellites with a long cycle, and the real-time performance of fault discovery is poor; 2. The storage resources on the satellite are limited. If the communication fault with the ground has not been established for a long time, the previous satellite status information may Will be covered, so that some data on the ground will be missing, and important information may be lost

Although the satellite telemetry state information storage method can be used to replay the satellite turntable data, only the past information can be monitored
