A Distributed Space Mission Visual Simulation System Based on Time Synchronization

Abstract

The invention discloses a distributed space mission view scene simulation system based on time synchronization. The system comprises a time synchronization server providing a uniform time standard, an environment model server for maintaining a three-dimensional model and a virtual environment, a simulation deduction server which includes track dynamics, attitude dynamics and a coordinate system conversion calculation model and is used for providing data for view scene simulation, a data storage server storing measured data and simulation data and display terminals used for displaying different perspectives and view scenes. All the servers and the display terminals are accessed to the same gigabit Ethernet.

Description

Technical field [0001] The invention relates to a visual simulation technology, and more particularly, to a distributed aerospace mission visual simulation system based on time synchronization. Background technique [0002] "Satellite Navigation System Analysis and Simulation Technology" edited by Wen Yuanlan, 1st edition in December 2009; Chapter 7 "Distributed Simulation and Its Application in Satellite Navigation System" Yang said: Generally speaking, Simulation is the experimental study of the model, so the system simulation can be described as the technology, method and process of establishing the model of the system and testing on the model. Distributed simulation is the simulation process of constructing system models based on distributed systems and conducting experiments. [0003] Tan Weichi, "Spacecraft System Engineering", edited by Hu Jingang, first edition in April 2009; Chapter 3 "Analysis of Space Tasks" stated that a space mission is an engineering project that use...

AI Technical Summary

Problems solved by technology

In short, space missions are complex, expensive, harsh environment, impossible to maintain after launch, and require a very high success rate. These characteristics determine the status of simulation technology in its development

[0005] Most of the existing simulation programs are numerical simulation programs written in C language or FORTRAN programming language, the user interface is not friendly enough, the interactivity is poor, and the output results are digital text information, which requires a strong professional knowledge background to be able to interpret, which is not intuitive Reflect the changes in the state of motion of the spacecraft and the space-time relationship among the spacecraft, the earth, and the sun

[0006] In the increasingly complex situation of space missions, the computing and display capabilities of stand-alone systems have been difficult to meet the needs of visual simulation
