摘要
研究了天地基导航信息融合对导航系统GDOP的改善;提出了利用样条函数表示航迹的思想,并给出了利用融合天基GPS导航信息与地基导航信息来提高导航系统GDOP的方法.文中详细推导了样条函数表示航迹条件下导航系统的GDOP表示方法.仿真结果表明:这种方法可有效地改善导航系统的GDOP.
This paper discusses the improvement of GDOP by navigation data fusion based on air & ground. The idea explains that the trajectory can be denoted by using spline function. The method improves navigation GDOP which is based on the data fusion air & ground navigation data. How to get the GDOP is deduced in detail. By the simulation result,we can get the conclusion that there is an effctive improvement of navigation GDOP by using the method of data fusion based on air & ground.
