2022-06-24T00:00Z 2215/5 175 -: The GNSS instrument mechanically connected to two 90 cm trihedral corner reflectors for co-locating (In)SAR ascending and descending radar observations. The GNSS monument itself consists of a SECO mount, on top of a 3.5 m heigh 8 cm diameter stainless steel pipe, with a 35 cm square strudded footplate. On each side, a 90 cm corner reflector for ascending and descending InSAR tracks is attached to the pole. A GCP for LIDAR measurements (the top plate of the IGRS) is present. The whole assembly is mounted on a concrete bunker on top of carboon bedrock. The bunker is 1 meter below the ground and 7 meter high. The top plate of the IGRS (CGP for Lidar) is 2.1 meter above the concrete bunker and xx meter above the ground. The GNSS antenna is xx m above the ground
