The Research On Jamming Simulation Technology Of Satellite Navigation Based On Stk

In the numerous navigation systems, the research on GPS navigation system is particularly prominent, and the GPS navigation system has been represented a strong superiority especially in the info-war. The power of information control is as important as the power of space control and sea control for the victory of the battle. Therefore, in the future war, GPS navigation system will become the key of the support system, which is used to perform accurate command and control, accurate striking and distribution of troop. Studying GPS system and its jamming methods, is significant for developing GPS confrontment, finding policy to win in the space information field and establishing war policy in the future.In order to study the carrying platform technology of GPS air jammer, the jamming carrying platform technology of satellites formation and orbit maneuvering are studied on the basis of space dynamics and STK (Satellite Tool Kit) simulation software. On the basis of the study on the jamming application mode of the two kinds of platforms, the jamming scheme is proposed, and the best jamming strategy is gained.Firstly, the jamming implement is modeled on the special mission. Based on the application of GPS and the analysis of the jamming feasibility and the characteristic of the jamming targets and the jamming methods, the selected reason of the jamming platform is given, so the flying around and the orbit maneuvering are modeled. For the formation flying of satellites technology, through the coordinate systems and conversion, Hill equations of dynamics model is in-depth studied, and several space-formation formations are designed. The method is correct validated by the Matlab software. For the orbit maneuvering technology, through studying the most efficient orbit transfer manner in energy and time, and the orbit maneuvering opportunity in coplanar cases, an optimum model of orbit maneuvering is developed and analyzed, the better scheme of orbit maneuvering is educed. Secondly, the assistant simulation software STK is studied. The STK/Astrogator module and STK/Connect module are studied emphatically. The STK-RTI Middleware which is based on the formation flying of satellites is designed and implementedFinally, the jamming application mode of flying around jamming of the enemy's military satellites and orbit maneuvering jamming of an enemy aircraft for combat in space are analyzed and designed, which are simulated and implemented with STK. The result of simulation is analyzed and the better jamming platform is gained.
