Description

technical field [0001] The invention relates to an HLA-based space network visualization simulation system and simulation method. Background technique [0002] With the development of space network, the use of simulation software to simulate space network to complete space exploration tasks, and to verify space communication protocols and coding techniques have been highly valued at home and abroad. But at present there is no all-round simulation software that can realize the simulation of space network visualization at the same time, such as the visualization of space transmission tasks while simulating the space network transport layer protocol. [0003] First of all, the space network simulation is a simulation process with a huge amount of data and a strong integration. Since the space network is a collection of communication and navigation functions composed of various orbiting satellites and remote sensors, different data information needs to be differentiated and fus...

AI Technical Summary

Problems solved by technology

When simulating space communication transmission and performing mixed environment testing and evaluation, it is necessary to capture details and analyze the characteristics of space network simulation. Due to various factors such as space network environment and communication links, it is extremely difficult to achieve dynamic effects of space network simulation, making Visual technology cannot be directly integrated

[0004] Secondly, because the dynamic topological structure of the space network changes, the existing simulation software cannot simulate the actual topology and topology changes and other related information. It is difficult to see the simulation results of the space network protocol and the transmission of space network communication detection tasks. The simulation of random, stochastic, and dynamic real systems is difficult to model and analyze dynamically
