Abstract
The paper reports on the principles, experiences and first results made with a low cost satellite based sensor network recently developed especially for landslide monitoring. Central idea of the system is the permanent broadcast of carrier phase (CP) raw data from the sensor nodes to a base station, where an automated near real time processing (NRTP) takes place. Low cost means the utilization of simple navigation receivers with the required capability of read-out the CP raw data. Depending on the different filter options during analysis the system generates sensor node positions with sub centimetre accuracy. The challenge of the still ongoing development is to have a flexible, robust (weatherproof), commercial off-the-shelf GNSS sensor network of high-quality available – concerned not only for landslide monitoring in future.
