DGPS/INS Integrated Navigation System

Zhang Chongwei Chen Yongbing  
This paper breifly describes the characters and shortcomings of two main technical ways to improve the precision and performance of GPS (that is, DGPS and GPS/INS). A scheme for integrating DGPS and INS has been proposed. The paper researches the design of Kalman filter for this kind of system, and a computer simulation has been made. The result indicates that the DGPS/INS integrated system can provide a real time positioning precision of 1~2m.
