Title: HIGH-PRECISION REAL-TIME SATELLITE POSITIONING METHOD
Abstract:
A high-precision real-time satellite positioning method comprises: establishing a polygonal satellite positioning receiver array comprising a plurality of satellite positioning receiving mechanisms; transmitting, by the satellite positioning receiving mechanisms, and to a processor module, respective IDs and observation coordinates; computing, by the processor module, a physical geometric pattern and an observation geometric pattern; comparing the physical geometric pattern and the observation geometric pattern to extract an offset vector caused by an error, and to generate an offset vector function library; and subtracting the offset vector from an observation value of a phase center of antennas of the satellite positioning receivers to obtain a corrected satellite positioning value. The embodiment can eliminate a positioning error present in satellite positioning receivers, increasing positioning precision significantly, having features such as a reasonable design, high precision, low costs, and being easy to use. The embodiment can be promoted to large-scale civil applications in high-precision real-time satellite positioning and navigation.
