The use of low-cost geodetic sensor technology opens up promising prospects for comprehensive and cost-effective monitoring of climate-related coastal risks. This presentation will introduce two types of sensors: First, low-cost GNSS receivers that can provide precise position data in real time. They are ideal for identifying subsidence, coastline displacement or deformations of protective structures along the coast. Secondly, MEMS sensors will be presented, as used in geodetic research, in particular for recording accelerations, inclinations or vibrations. These properties can be effectively utilised in the field of climate-related coastal risks. The fusion of GNSS and MEMS data increases reliability as well as spatial and temporal resolution. In addition, geodetic monitoring data becomes easier to interpret, especially for dynamic objects or in sensitive coastal areas that are difficult to access. Data fusion as a challenge will be discussed together with the topics of calibration and long-term stability. Finally, integration strategies in the context of the Internet of Things (IoT) and integration into monitoring networks will be discussed.
