<p align="justify"> Beidou navigation satellite system (BDS) is a navigation system that is owned by China which currently has completed the second phase of the development phase of their satellite system and has a navigation service area in the Asia-Pacific region. China and with a target to have a high degree of accuracy and level of confidence, China also has a dream to complete this navigation satellite system on 2020 . At this time there is only few researches about this Beidou, especially in Indonesia. This research aims to identify the performance and the influence of Beidou which refers the degree of accuracy and precision GNSS observation. <br /> <br /> <br /> <br /> This study is based on the results of data processed using LGO and CGO software . The measurement method used in this research is the method of static network and RTK. The data is collected by using the GNSS surveying tool CHC X91. The result shows that Beidou improves the precision of the observation which is improvement of ppm value for 8% and decreasing the standard deviation value for the easting coordinate for 2.6 mm, northing coordinates for 0.8 mm, and the height coordinates for 2.7 mm. In terms of accuracy, Beidou impacts to the increasing on the value of high coordinate accuracy for 0.8 mm, but there is a drop to the level of accuracy for 3.7 mm in easting coordinate, and in northing coordinates for 1.9 mm. By using the RTK method, a combination between GPS satellites and Beidou satellite provides data retrieval results of less than 10 seconds with the average value of Root Mean Square (RMS) in this study is 0.003 m. <p align="justify"> <br />
