每年，the Council of European Geodetic Surveyors (CLGE)组织a student contest旨在奖励年轻人在各个与测量相关地区的工作。今年，CLGE Students' Contestwas awarded at INTERGEO in Berlin on 27 September 2017.

今年授予的三个类别是：

• Geodesy and Topography,

• GIS, Mapping and Cadastre and

• 伽利略，埃格诺斯，哥白尼。

Leica Geosystems很高兴支持Geodesy和地形奖。这awarding paper for this year’s category was: “引入GCG2016作为综合测量空间参考的组成部分，使用SAPOS对GNSS-NHN高度的经验准确性进行了研究” by Vitaly Winter, Geodesy and Geoinformation student at the Faculty of Agriculture at University of Bonn, Germany. The awarded paper is a local and practical study which shows the opportunities and accuracy of geodetic GNSS receivers for cadastral and engineering surveying.

这研究显示首次可实现的准确性SAPOS HEP(Network-RTK) after the introduction of the new geospatial reference 2016in a scientific investigation using Leica Geosystems GNSS equipment.

这goals and objectives of the investigation were:

• 为了获得特定区域中GNSS-NHN高度的经验精度值

• Compare target and measured values

• 得出准确性Quasigeoid型号GCG2016using Leica Geosystems GNSS receivers

• 确定高度测量准确性取决于的因素。

一个Leica GS16自学习GNSS智能天线and aLeica CS20现场控制器were used to obtain normal heights by connecting with the network-RTK-service HEPS from the provider SAPOS. 138 official height markers in the Rhine-Sieg-county in North Rhine-Westphalia, Germany were measured. The used data type collected included useful information on normal heights, ellipsoidal heights, undulation values, DOP values and measured positions (duration) in the standard Leica Viva format.

这Leica GeosystemsGNSS equipment played a crucial role in achieving the conclusive results of the investigation.“The hardware [of the Leica GS16 and CS20 Field Controller] is reliable and conveniently designed. On top of this, the software settings can be deeply customised to improve reliability and the workflow. The chosen equipment had to receive various satellite systems, such as GPS, GLONASS, Galileo and Beidou with a fast and stable communication,”冬天说。

调查测试的结果是卫星定位服务（SAPO）使用的网络RTK方法的精确定位。这些观察结果得出了使用Leica GeoSystems GNSS解决方案的高度准确性和精度。“ GNSS技术正在不断改进，因此我的研究结果可用于与未来的研究或其他地区的类似研究进行比较，”结束了冬天。
