Test cases and experiments were discussed intensively by the project team. All project partners investigated the initial station selection about feasibility of installing active transponders and about SAR reflection properties of the nearby environment (accessibility; local tie possibility w.r.t. tide gauge and/or GNSS; obstacles surrounding the site; radio frequency interference). For the selected stations, approval from national authorities to operate active instruments at specific locations was acquired before installation.
The final network design is shown in the picture below.
Note: The stations described below were in operation at the indicated positions during the project runtime. Some have continued to operate on site beyond the end of the project. We cannot make a detailed current statement as to which stations are currently still in operation at the indicated locations.
Initially, the ECR was mounted to the site between 14.02.2020 and 28.09.2020. Due to malfunction, the ECR had to be dismounted and sent for repairs, after which the ECR was remounted to the site. This caused height-wise change in the coordinates.
