A Method to Improve the GDOP of the Navigation System

MA Yan\ XIE Jing\|wen (Beijing Institute of Tracking & Telecommunication Technology, Beijing 100094, China)  
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.
