BDS辅助GPS高程拟合精度分析

The Construction of the Coal Mine Production Process Simulation System

随着GPS与GLONASS系统达到完全运行能力、BDS达到亚太地区完全运行能力,与之对应接收机也呈现了多系统兼容的状态,奠定了多GNSS环境下高程拟合的基础。在对已有GPS系统高程拟合相关方法研究的基础上,统一了它们时空基准;构建了BDS与GPS系统组合定位的数学模型;处理了某工程D级网观测数据;分析了引入BDS系统后,GPS高程拟合精度变化情况;给出有益的结论可以借鉴到相关的工程或领域中。

In view of the situation that the coal mine production conditions were harsh and the production process was complicated,using virtual reality technology,3d modeling software-3DS Max and virtual reality software-VR Platform editor,according to the system design scheme,the coal mine production operation process simulation system was built.It made contribute to protect the safety of the coal production and enhance the miners' safety awareness and production systems optimized design.(Liu Yajing et al.) Analysis on the Precision of GPS RTK Improved by BDS- ODS system was our self- developed satellite navigation and positioning system,which was the third reach full operational capability(regional) system followed GPS and GLONASS.The system was a hybrid constellation of GEO,MEO and IGSO satellite,especially IGSO satellite could overcome effectively the somehow of GEO satellite.For this reason,it was a theoretical value and guiding significance for specific projects that analysis on the precision of RTK combination of BDS and GPS was expanded taking the topography measure project of a City.
