A high-complexity spacecraft gnc data real-time intelligent processing system

Abstract

A real-time intelligent processing system for GNC (Global Navigation Chart) data of a high-complexity spacecraft comprises a server side, a client side and an Ethernet, wherein the server side and the client side communicate with each other through the Ethernet; the server side comprises an acquisition module, an unpacking module, a decoding module, a real-time processing module, a communication module and an interrupt scanning module. The acquisition module receives telemetric original code data; the unpacking module parses the data according to the CCSDC protocol to extract GNC data; the decoding module decodes the GNC data into physical parameters according to a decoding table; the real-time processing module stores the related information corresponding to the physical parameters in a real-time database; the interrupt scanning module monitors the state of the related information corresponding to the physical parameters and stored in the real-time database. The real-time intelligent processing system adopts a distributed architecture, is stable and reliable, and high in real-time performance, universality and expansibility, and effectively meets the real-time automatic processing requirement on GNC mass testing data of the high-complexity spacecraft.

Description

technical field [0001] The invention relates to a high-complexity spacecraft GNC data real-time intelligent processing system, which belongs to the technical field of spacecraft GNC data processing. Background technique [0002] In recent years, with the deepening of my country's space missions, the complexity of spacecraft has become higher and higher. Taking the third phase of the lunar exploration project as an example, its main task is to develop and launch new lunar probes to achieve soft landing on the moon and unmanned Sampling and returning samples to the ground to carry out lunar scientific exploration and ground analysis of lunar samples. As the first model of the third phase, the CE-5 probe consists of a returner, an orbiter, a lander and an ascender. Its ground test and in-orbit flight will leave a lot of valuable data for my country's deep space exploration. In the ground test, the GNC system has the characteristics of the most types of test equipment, the large...
