摘要
在卫星定位系统中,远近效应是影响定位精度的重要因素之一。文中分析了伪卫星远近效应在卫星定位导航中的影响,提出用脉冲调制方式解决远近效应,分析其优缺点,并最后提出一种时分与码分相结合的方法来更加完善地解决远近效应。
In satellite position system,the near-far effect is one of the import;ant factors that influenced the position accu- racy.This paper analyzed the influence of pseudolite near-far effect in satellite position navigation,put forward to use pulsing to solve near-far problem,and analyzed its advantage and disadvantage,brought a new method of using time d(?)- vision combined with code division to solve near-far effect perfectly at last.
