Abstract

The existing positioning performance analysis of navigation equipment does not reflect various test environments. Performance analysis using GPS simulator is a simple performance analysis reflecting a zero correction error. And field test also is performance evaluation level in several environments. Considering differential positioning performance of navigation equipment depends on characteristics of correction error, it is necessary that correction error generation algorithm is able to reflect a various environment conditions. This paper proposes a correction error generation algorithm for differential positioning performance analysis of navigation equipment. And this paper will implement PC-based verification platform consisted of DGPS reference station receiver and GPS simulator to verify the proposed correction error generation algorithm, and compare correction by the proposed correction error generation algorithm with correction calculated in commercially available off-the-shelf receiver for DGPS reference station.
