Notes
- 2020-01-28T12:00Z 2090/2 028 -
- 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 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. 1.416 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 XX m long foundation piles to
sub-surface sand deposit. On top of the sand layer is a XX m peat toplayer.
The top plate of the IGRS is 1.101 meter above the concrete block, the GNSS monument
is 1.416 m above the top-plate (LIDAR GCP).

- The IGRS was mounted on the concrete plate, but the orientation of the corner reflectors was 90
degrees off. InSAR data for the CR is not reliable for this period.
- 2020-01-21T11:00Z 2089/2 021 - 2020-01-28T12:00Z 2090/2 028
- The receiver was installed and antenna was mounted directly to the pole, but without SECO mount.
The corner reflectors were oriented approximately, but the final orientation was not done until Feb.
28, 2020. GNSS measurements for this period have been deleted. InSAR data for the CR is not
reliable for this period.
