Single Point Positioning using BeiDou BDS-3 Constellation

Abstract

Global Navigation Satellite Systems (GNSS) are used for providing all weather positioning and navigation solution to users across the world. The premier GNSS constellation, United States' Global Positioning System (GPS) was fully functional by 1993. With the configuration of GPS L1 C/A Navigation message (LNAV) readily available, most of the applications rely on the GPS. However, the well-known documentation has also led to the signal being vulnerable to spoofing and jamming attacks. Chinese BeiDou BDS-3 provides global coverage over the Asia Pacific region with additional security features embedded in civil signals deeming it suitable to be used as an alternative positioning scheme. This research paper discusses the alteration of GPS Easy Suite for positioning using BDS-3 B1I measurements. Data is collected through a survey-grade receiver and positioning accuracy for BDS-3 is compared with GPS. It is noted that BDS-3 B1I provides higher positioning accuracy than GPS LNAV signals manifesting itself as a better alternative if not the sole solution provider for single frequency GNSS users.
