摘要
星差分(星基差分)GPS接收机SF2050G使用NAVCOM公司在全球建立的StarFire系统,可在全球范围内使用无自架基站实时差分服务,标称可得到WGS-84坐标系下分米级的定位精度,为将该仪器应用于控制测量中,对4台仪器进行了一个工作日测试,采集数据40个,分析测试数据得出了该机型机器在本工作日内的精度,将仪器应用于地理国情普查项目内蒙古部分测区的像控作业,与已知控制点坐标对比得出该仪器的精度,并对该仪器未来的应用方法与方向做出了一定的探索性设想。
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 .
