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.
