New Systems, New Signals, New Positions – Providing BeiDou Integration

P. Fairhurst, X. Luo, A. Aponte

Abstract:	Leica Geosystems is a world leader in GNSS positioning, and in utilizing innovative methods for providing High Precision GNSS solutions. With the advent of new GNSS constellations, such as BeiDou and Galileo, amongst other signals and regional systems providing a significant increase in Satellite availability, new methods are required to fully realize the potential benefits of these additional GNSS constellations. However, before these new systems potential can be fully realized, we must first understand what advantages they can provide when being used in a High Precision GNSS solution. Leica Geosystems’ previous leading edge work on GLONASS observation interoperability (Takac et al., 2012) and (Takac and Grgich, 2009) shows that there are many challenges involved with incorporating new GNSS constellation into a position solution, and careful evaluation needs to be carried out to understand the behavior and characteristics of these systems. This paper presents results from integrating BeiDou into Leica Geosystems’ GNSS technologies from SmartTrackTM through to RTK positioning and SmartCheckTM. An assessment of the BeiDou constellation, signal, orbit and clock characteristics allows a comparison against existing GNSS systems and further results show the GNSS positioning improvements that can be gained through the addition of BeiDou satellites and signals, as well as some of the challenges that need to be addressed in order to provide the highest quality GNSS position solution in all environments without compromising on reliability. Leica Geosystems AG is once again leading the way in providing technologically innovative solutions to meet the demands of all users of High Precision GNSS solutions.
