Performance Analysis of Beidou Precise independent point locationconsidering ISB parameters in complex Transmission Line Environment

Abstract This paper analyzes the inter-system deviation between B1I/B3I semaphores and B1C/B2a of Beidou-2 Beidou-3 semaphores, precision single independent point locationperformance / under condition semaphores. Through experiment, system parameters two satellite systems are greater than that both have good intra-day inter-day stability. The participation can significantly improve positioning function one Beidou-2. location astringent time is reduced by about 51.9%, accuracy increased 46.1%. Compared with after participate in locationcalculation, greatly shortened. After estimating correcting parameters, static dynami PPP shortened 8.8% 12.6% respectively, promoted 7.1%.
