Towards a dynamic reference frame in Iceland
There is a growing need for geodetic reference frames that on a national level support the increas-ing use of global positioning services. Today, the vast majority of countries have their own national ref-erence frame. In Europe this frame is normally aligned to ETRS89. This system is co-moving with...
