小倾角同步卫星通信

同步卫星工作寿命必须考虑各种因素，当它接近寿命末期时，尽管星上有效载荷仍能有效工作，但剩余的燃料已无法继续进行南北位置保持，只能进行东西位置保持。这时如果利用该星进行小倾角通信，就能有效地延长卫星工作寿命，节省大笔经费。同时就它给地面卫星通信系统带来的新问题做了深入研究，给出了不同倾角情况下定量分析结果，并针对不同的通信体制，提出了相应的解决方法。

SATELLITE COMMUNICATION IN GEOSYNCHRONOUS ORBIT WITH SMALL INCLINATION

he operation lifetime of a geosynchronous satellite depends on many factors. In the end of its lifetime, the payloads in the satellite are still working well,but the satellite can't be controlled in north-south direction for fuel shortage in the satllite, it can be controlled enly in west-east direction. If the satellite work in an inclined orbit, could use this satellite for more years and save a lot of money. On the other hand, it also brings about new problems in communication. This paper discusses the problems deeply and gives the calculation results on the condition of different inclinations and the ways to solve the problems.
