Discussion on the Integrated Approach of the CPS/INS and Precision Analysis of the Navigation Performance
Abstract
This paper discusses the advantages and shortfalls of the integration of two navigation systems, namely GPS and INS. It discusses a method of integrating them by the use of the pseudo range and pseudo range-rate measurements of the GPS-receiver to integrate GPS with INS. Because the measurement errors of the GPS are all different, the numerical simulation of the integrated navigation capability of a plane had to be computed under different conditions of the differential machines. Details of the accuracy analyses were also made accordingly. The results showed that such integrated system of navigation provided the accuracy which could not be achieved by either the GPS or the INS alone. By integrating the differential GPS receiver with the INS, the errors in position could be further reduced. The integrated navigation thus opens up a new area of application to be used for aircraft approaches and landings.
