Notes

- The GNSS instrument mechanically connected to two 90 cm trihedral corner reflectors for
co-locating (In)SAR ascending and descending radar satellite tracks. The GNSS monument
itself consists of a SECO mount, on top of a 2.5 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. 1.42 m below the GNSS monument a
GCP for LIDAR measurements (the top plate of the IGRS) is present. The whole assembly
is mounted on a concrete block fixed to 3 steel/grouted 11.5 long foundation piles to
sub-surface sand deposit. On top of the sand layer is a 8 m peat toplayer.
The top plate of the IGRS is 1.122 meter above the concrete block, the GNSS monument
is 1.416 m above the top-plate (LIDAR GCP).
