Compass Navigation Satellite System is a precise satellite navigation which is independently created by Chinese scientists. Base on its characteristics of providing all-weather, continuous, real time and high accuracy three-dimensional positioning, it has been widely concerned on military and the civilian. At present, the first phase of Beidou second generation satellite system has been put into trial operation and the second phase of Beidou second generation satellite system is speeding up research and development. The number of received satellites under natural condition with different time and different places can be predicted through Ephemeris. However, it generally requires that the satellite positioning receiver can position stably while the missile's attitude keeps changing in missile's application field. The satellite usability under the condition that missiles in different poses, especially under the condition of big pitch attitude is very important to navigation and guidance scheme design. This paper formulates reasonable simulation scheme with Beidou satellite constellation distribution, typical microstrip antenna directional diagram and typical ballistic. It focus on the simulation of some key parameters, such as the number of Beidou satellites, geometric distribution and positioning success rate of Beidou area navigation system and Beidou global navigation system in different time and places when the single antenna or dual antenna layout scheme has been adopted, which under the condition of great pitching against missiles or in different course. Meanwhile, it gives the analysis of satellite availability and guidance. The simulation scheme and the result of simulation and analysis in this paper has important engineering significance to make full use of the Beidou satellite in the process of missile trajectory planning and navigate tactic designing.
