挪威测绘局与设在尼奥勒苏德的空间大地观测站一起参加了“VLBI测量欧洲地壳垂直运动”项目。该观测站是一个为全球大地测量网络做出贡献的多参数监测站。由于地处北极的偏远地区，空间站构成了这些网络的独特基石。空间站记录的环境参数包括海平面、地表变形和重力。阿尔弗雷德-韦格纳研究所附近的研究站可以获得气象观测，包括每天的无线电探测仪。在项目中，NMA为项目工作计划中定义的几项任务做出了贡献。对于每个任务，都会报告其状态。到目前为止，进展接近工作计划，此处报告了一些额外的贡献。将欧亚板块的水平台站速度与NUVEL-1A型模型预测的速度进行了比较，结果吻合较好。GPS与VLBI测站速度的比较结果表明，垂直速度的计算结果有很大的不一致，其原因尚不清楚。
The Norwegian Mapping Authority (NMA) participates in the project ”Measurement of vertical crustal motion in Europe by VLBI” with the space-geodetic observatory at Ny-Ålesund. This observatory is a multi-parameter monitoring site contributing to global geodetic networks. Due to its remote location in the Arctic, the station constitutes a unique cornerstone for these networks. The environmental parameters recorded at the station include sea level, surface deformations and gravity. Meteorological observations including daily radio-sondes are available for the nearby research station of the Alfred-WegenerInstitute. In the project, NMA contributes to several of the tasks defined in the project workplan. For each task, the status is reported. Up to now, progress has been close to the workplan with some additional contributions reported here. The comparison of horizontal station velocities to those predicted by the NUVEL-1A model for the Eurasian plate shows a good agreement. Comparison between GPS and VLBI results for station velocities results in significant disagreement for vertical velocities, the reason of which remains to be clarified.
