The Function Design Of Simulation Program About Satellite Orbit And Scanning Coverage

With the rapid development and the gradual improvement of human society,information has become an indispensable part in the life. At the same time, thevaluable information existed in elsewhere. As one of the important access platformsof todays all kinds of valuable information—satellite, attracting each county to payattention to its development of engineering technology. Satellite is a product of thedevelopment and demand of modern science and technology. It is also a collection ofvarious high-tech technologies. The process of its development and research isextremely long, arduous and complex. It not only needs the hard work of generationsof scientific researcher, but also needs a powerful financial resource of a county tosupport. High-risk characteristics inherent in its industry, to a certain extent, hamperthe development of satellite technology, with the purpose of decreasing the risk ofindustry and enhancing the success rate or yield ratio, using simulation technology totest the audit before launching the satellite has became a kind of important means.As an important part of this technology, Satellite orbit scanning coveragesimulation is also an important content in the field of space technology research atpresent. In terms of the current research status and development in this field, thisarticle firstly introduces the basic satellite knowledge which is related with thesimulation of satellite orbit design, such as time system, coordinate system, tracknumber, etc; then analyzing the moving of satellite orbit and related dynamics,meanwhile, studying the satellite trajectory, scanning coverage and the realization ofsimulation; then making certain study on simulation technology by combing with theJava programming language, making program implementation to trajectory simulationand coverage analysis simulation and making corresponding function design andintroduction to the simulation program; next, making verification and giving theresults by some experiment data; finally, analyzing the current problems and givingproperly prospect to the research analysis of satellite simulation technology in thefuture.
