Abstract

Abstract : Purpose: GPS kinematic positioning suffers performance degradation in constrained environments such as urban canyons, which then restricts the application of high-precision vehicle positioning and navigation within the city. In December 2012 the BeiDou Navigation Satellite System (BDS) regional service was announced and the combined BDS/GPS kinematic positioning has been enabled in the Asia-Pacific area. Previous studies have mainly focused on the performance evaluations of combined BDS/GPS static positioning. Not much work has been performed for kinematic vehicle positioning in constrained observation conditions. Design/methodology/approach: In this study, three vehicle experiments under three observation conditions, i.e., an open suburban area, a less dense non-central urban area, and a dense central urban area, are investigated using both the code-based DGNSS and phase-based RTK modes. The comparison between combined BDS/GPS and GPS-only vehicle positioning solutions is conducted in terms of positioning availability and positioning precision. Findings: Numerical results show that the combined BDS/GPS system significantly outperforms the GPS-only system in poor observation conditions, whereas the improvement was less significant in good observation conditions. Originality/value: Thus, this paper studies the performance of combined BDS/GPS kinematic relative positioning in various observation conditions.
