Flight data analytic recording device, system and method for spacecraft

Abstract

The invention provides a flight data analytic recording device, system and method for a spacecraft. The flight data analytic recording device is mounted in the spacecraft and comprises a data acquisition module, a data storage and protection module, a rapid data analysis and interpretation module and a telemetering and location transmitting module, wherein the data acquisition module acquires multiple spacecraft data, sends the to-be-stored data to the data storage and protection module, and sends performance monitoring data to the rapid data analysis and interpretation module; the data storage and protection module compresses and stores the to-be-stored data; the rapid data analysis and interpretation module quickly interprets the performance monitoring data on line and outputs failure data to the telemetering and location transmitting module; and the telemetering and location transmitting module downloads the failure data and is simultaneously used for transmitting an emergency locating signal after the spacecraft is in contact with the ground. The on-orbit state of the spacecraft can be monitored, failures can be diagnosed, data are downloaded to the ground, and the state of thespacecraft can be analyzed when the spacecraft falls on 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...

AI Technical Summary

Problems solved by technology

During the falling process of the satellite, friction with the atmosphere produces high-temperature ablation, and its temperature can reach up to 3,000 degrees Celsius, and the duration is relatively short.
