ABSTRACT: Downie Slide is an ancient, slow-moving landslide roughly nine square kilometres in plan with an estimated volume of 1.5 billion cubic metres. BC Hydro has monitored the slide for more than 50 years and recently installed a new automated surface displacement monitoring system using GNSS technology. The application is unique because the equipment was installed on towers up to 5.5 metres in height and because the GNSS receivers are powered by batteries with solar recharge. This paper describes the design of the system and presents initial performance data. RÉSUMÉ Downie Slide est un ancien glissement de terrain à déplacement lent d'environ neuf kilomètres carrés en plan avec un volume estimé à 1,5 milliard de mètres cubes. BC Hydro surveille le glissement depuis plus de 50 ans et a récemment installé un nouveau système automatisé de surveillance du déplacement de surface utilisant la technologie GNSS. L'application est unique car l'équipement a été installé sur des tours jusqu'à 5,5 mètres de hauteur et parce que les récepteurs GNSS sont alimentés par des batteries à recharge solaire. Cet article décrit la conception du système et présente les données de performances initiales. INTRODUCTION
