GNSS 包括 GPS、GLONASS、GALILEO 和 BDS 四大卫星定位系统，研究发现相比单一的 GPS 定位系统，GNSS 多星系统在定位精度、系统可靠性及安全性方面具有明显优势。在介绍多星座组合导航算法及系统定位原理的基础上，结合中海达 V30接收机在控制网设计及控制点位布设方面的灵活性，阐述了 GNSS 技术在广东省阳山县某矿区控制测量中的实际应用情况。 HGO 软件在内业数据处理各环节的操作表明，HGO 解算的数据成果精度大幅提升，点位平面中误差由原来的16.3 mm 提高到4.78 mm。同时，GNSS 技术在矿区控制测量中能克服地形复杂及植被覆盖区带来的不利影响，有效提高作业效率，从而达到理论技术指导生产的目的。

The GNSS technology predominately includes four global positioning systems,namely,the GPS, GLONASS,GALILEO as well as BDS.The results presented that the GNSS multi-satellite system had significant advantages in positioning accuracy,system reliability and safety compared with the single GPS positioning system.On the basis of introducing more integrated navigation algorithm and positioning principle,combined flexibility of the Hi-Target V30 receiver in the aspect of control network design and the control point layout,we described the application of the GNSS technology in control survey at a mine area in Yangshan county, Guangdong Province.Operation of each section of the data processing with the HGO software demonstrated that precision of the data calculated by the HGO was enhanced greatly,meanwhile,error in point plane improved from 16.3 mm to 4.78 mm as well.In addition,the GNSS technology used in mine area control survey can overcome the negative influence of the complex terrain and vegetation coverage,and improve the working efficiency,and finally aim to guide the production with the theory of technology.
