Abstract

The invention provides a spacecraft flight data analysis and recording device, system and method. The device is installed inside the spacecraft, including: a data acquisition module, a data storage and protection module, a data rapid analysis and interpretation module, and a telemetry and positioning launch module; The data acquisition module acquires multi-channel spacecraft data, sends the data to be stored to the data storage and protection module, and sends the performance monitoring data to the data rapid analysis and interpretation module; the data storage and protection module compresses and stores the data to be stored; The data rapid analysis and interpretation module quickly interprets the performance monitoring data online, and outputs the fault data to the telemetry and positioning launch module; the telemetry and positioning launch module downloads the fault data and is used to launch emergency positioning after the spacecraft touches the ground Signal. The invention can monitor the on-orbit status of the spacecraft, diagnose faults and transmit the data to the ground, and can analyze the status of the spacecraft when the spacecraft falls to the earth.

Description

technical field [0001] The invention relates to the technical field of data interpretation and analysis, in particular to a spacecraft flight data analysis and recording device, system and method, which are used for collecting and storing spacecraft data, safety protection, status monitoring, real-time diagnosis and selective data downloading. Background technique [0002] On-orbit state monitoring and fault diagnosis of spacecraft, such as rockets and satellites, are the key and foundation of spacecraft health management. For a long time, my country's spacecraft mainly track and measure the spacecraft closely through the ground measurement and control system, and manually analyze the data transmitted by the spacecraft's telemetry link, so as to realize the state monitoring and fault diagnosis of the spacecraft. However, as the number of spacecraft in orbit in my country continues to increase, the failure rate of spacecraft increases, and the workload of data analysis also i...
