Design And Software Implementation Of Mars Deep Space Channel Modeling And Visualization Simulation System

With the progress of the times,all countries in the world are actively conducting deeper exploration in the field of deep space exploration.At present,the center of gravity of China's space development plan is gradually shifting away from the direction of Mars exploration.The design and implementation of the simulation and visual simulation system for Mars deep space channel Realization of this project has a very positive effect on space exploration activities related to Mars exploration.In this paper,the actual functional requirements and performance indicators of the simulation system are given.On this basis,the Mars deep-space channel modeling and visualization simulation system is designed and implemented.The system is divided into two modules,which are the channel simulation Unit and in-orbit simulation unit.Then,this paper further divides the channel modeling in Mars environment into the interstellar space segment channel and Mars near segment segment channel,simulates and analyzes the key influencing factors such as propagation path loss,Doppler shift,noise and Mars environment and finally the channel model provides the theoretical support for the realization of the channel simulation unit in the simulation system.Then,the design and implementation of channel calculation module,STK verification module,CPCI driver module and hardware program module in the channel simulation unit are described in detail.And the specific operation flow,functional block diagram,implementation details and optimization of the corresponding module are given means.While giving the technical scheme and concrete realization of the parameter configuration module and the remote control module of the on-orbit simulation unit,the key technologies of OpenGL are researched in depth.Several rendering algorithms of contrast transparent objects are emphatically analyzed.Finally,the deep peeling algorithm is actually applied Mission in-orbit simulation unit,the perfect realization of the Mars satellite orb real-time three-dimensional image dynamic visualization.Finally,software and hardware inter-modulation of Mars deep space channel simulation and visualization simulation system is carried out.The result shows that the whole software system cooperates well with the underlying hardware and can simulate the space communication channel of Mars according to the user's incoming channel parameters Real-time satellite surround mission tasks in the orbit of three-dimensional images,all indicators meet the design requirements for the future development of deep space communication simulation system laid the foundation.
