Abstract

The invention provides a method for processing real time data of a lunar satellite microwave detector. The method comprises the following steps of: receiving an original bit-stream data transmitted by a satellite in real time; performing frame data processing on the original bit-stream data; extracting microwave detector data from the original bit-stream data; unpacking the data to obtain data blocks; carrying out physical quantity conversion and processing on the data blocks to obtain a format applicable to display, and displaying the data in a manner easy to be recognized by human eyes; analyzing the displayed data, and judging whether the data is normal or not; and when the data is judged to be abnormal, processing the data by using corresponding measures according to the types of the data. The processing method can process and analyze the scientific data and engineering data which are detected by the lunar satellite microwave detector in real time, so that engineering technical staffs can easily monitor the state of the detector and process abnormal condition.

Description

technical field [0001] The invention relates to a processing method for on-board instrument data, in particular to a processing method for real-time data of a lunar satellite microwave detector (MRM). Background technique [0002] The lunar exploration project is a systematic project for exploring the environment and resources of the moon. In the entire lunar exploration engineering system, it mainly includes departments such as lunar satellites, ground stations, and ground management stations. Among them, the lunar satellite is equipped with various scientific loads, which are used to detect various environmental and resource data on the orbit of the lunar satellite and the surface of the moon. The ground station has a data receiving subsystem for receiving and processing various detection data from satellites. The ground management station has established an operation management subsystem (OMS system), which is used to monitor whether the status of the satellite and its ...
