Development Of The Simulation System For Navigation Carrier Track

The simulation testing plays an important part in the research of navigation system. To simulate the track by computer can provide reference for the design and construction of navigation system, and verify the feasibility of navigation project or the new calculation way. So it is necessary to design track simulation software platform. This paper presents the design and implementation of the simulation software platform for track of navigation carriers. The software used for the simulation of orbit of satellite, ballistic trajectory of missile, maneuver of airplane and movement of car and ship, it can demonstrate the motion of carrier by using animation technique.Firstly this paper introduces some basic information about the track simulation, including time systems, coordinate systems, the definition of these systems and the transformation between different systems. The variety of navigation carriers brings the diversity of motion model. And a general-purpose track simulation program which should include different motion models. So a series of motion models are constructing since analyzes the motion rules of carrier, such as satellite, missile, airplane, car and ship. According the models, design idea and principles are put forward, and apply the Object-Oriented to system interface design. Implementing these technologies, a general and reusable track simulation program is realizing which will be modularized, with the coupling between modules reduced. Finally, the simulation software for track of navigation carrier, designed on the Microsoft Windows platform by using the VC++.NET, and the results of experiment show that the software has good performance.
