基于RTS的海上实时精密单点定位精度分析
Accuracy Analysis of Marine Real-time Precise Point Positioning with RTS Products
摘要
Abstract
In this paper,an experiment is conducted to perform the ship-borne kinematic GPS positioning in the Chinese Bohai gulf for one week.We verify the data availability and accuracy of four IGS real-time service (RTS) products,i.e.IGC01,IGS01,IGS02 and IGS03,received by BNC software.The precision of ship-borne GPS real-time precise point positioning (RT-PPP) with RTS products is analyzed.The results show that:the availability of four RTS products is all above 90% and IGS01 product has the highest availability of 97.68%.Comparison with IGS final precise orbit and clock products proves the root mean square (RMS) of four RTS orbit products is all better than 4 cm in X,Y and Z directions,and the standard deviation (STD) of four RTS clock products is 0.2ns.Contrasting to the result of post-processing precise point positioning (PPP) with IGS final products,the RMS of the aforementioned RT-PPP is no more than 7 cm for the horizontal coordinate component,12 cm for the geodetic height and 15cm for three-dimensional position.关键词
