| Abstract | An unstable rock slope situated between Port-Daniel and Chandler in the Gaspé Peninsula (Quebec) has been impacting a railway line for several decades. As part of a detailed monitoring program, a set of
artificial targets were installed in the vicinity of open fissures, on unstable rock blocks, and on infrastructure in fall 2009. These targets are remotely monitored by SAR (radar) satellite signals orbiting at an average altitude of 798 km to
measure slope movement. This paper briefly presents the site conditions at the Gascons rock slope and reviews the PTA-InSAR technique. It describes the installation of the corner reflectors, including the anchoring systems. |
