| Abstract: | The Star-based differential GPS receiver SF 2050 G use NAVCOM company StarFire system in the world , can be used on a global scale without from base stations in real time difference service , nominal WGS -84 coordinate system can be obtained under the decimeter level positioning accuracy , for the instruments used in the control survey , four instruments for the test one working day , 40, collect data analysis of test data , it is concluded that the precision of the model machine in this days , the instrument used in geograph-ical parts of Inner Mongolia national census project measurement area like homework , compared with known control points coordinates it is concluded that the precision of the instrument , and the application methods and direction for the future of the equipment is made some exploratory ideas . |
