Analysis Precision and Convergence of the Real-time Precise Point Positioning based on the IGS Real-time Products
摘要
Abstract
This paper first introduces the basic parameters of the real-time precision ephemeris and precision satellite clock error correction coefficient （ROCC for short, namely Real-time Orbit and Clock Correction） provided by the IGS organization. And the paper also presents the basic situation of the BKG Ntrip Client （BNC） software which can execute real- time single point positioning precisely. On this basis, the author selected 25 global IGS tracking stations, and analysed the effects of the 15 kinds of ROCC products on the precision and convergence of real-time precise point positioning on these stations based on the BNC software. The experimental results show that： using the BNC software, the real-time precise point positioning results based on 15 kinds of ROCC products can converge in about 15rain, and reach to an accuracy of about 6-8 cm positioning in the north direction and east direction, and the positioning accuracy of up direction is about 10-20 cm. Besides, the convergence time and location accuracy of different ROCC products has certain differences.关键词
