The earth orientation parameters (EOP) who connect the earth-fixed coordinate frame and celestial coordinate frame are the important input parameters for GNSS precise orbit determination (POD). The earth rotation parameters are also one of the core products of GNSS service. The third generation Beidou Global Navigation Satellite System (BDS-3) provides global high-accuracy service because of the benefit from Inter-satellite link measurement. It is of great significance to study the enhancement of inter-satellite link measurement on ERP products. This paper analyzes the mathematical relationship between ISL measurement and ERP, designs the experiment, and analyzes and summarizes the results. For BDS-3 constellation POD based on regional stations, the ISL measurement has improved the accuracy of orbit radial, along and cross directions by 97%, 60% and 46% respectively. xp accuracy of ERP pole motion improved by 69%, the length of day (LOD) accuracy improved by 69%. The results show that, in the integrated processing of BDS-3 POD and ERP, the ISL measurement has a significant enhancement on orbit and ERP accuracy based on regional stations. The experiment and conclusions in this paper are significant for high-precision ERP product solution with regional stations, which is applied to BDS-3 operation control system.
