| Abstract: | Using double difference module of BERNESE and Precise Point Positioning module of PANDA,the data of 120 days to 365 days in 2009 from Chinese coastal GNSS operational observing network was processed,and the results were analyzed and compared from the outer and inner accuracy.The results showed that the positioning precision of double difference of BERNESE is slightly better than that of Precise Point Positioning of PANDA. |
