Cost-effective monitoring of deep-seated landslides provides vital insights to understand their kinematics and is an important tool for preventing impacts on society. This study presents the results of monitoring campaigns, including the use of low-cost sensors, conducted at the Reissenschuh landslide (Tyrol, Austria) between 2016/05 and 2021/12. Time series of displacement, velocity and the rotational movement component were recorded at 31 observation points based on periodical measurements with the help of a differential global navigation satellite system (DGNSS) and a permanent system combining a low-cost real-time kinematic (RTK) single-frequency DGNSS and a micro-electro-mechanical system (MEMS) accelerometer. Rotational movement components derived from both monitoring campaigns are analysed and interpreted in terms of the landslide's kinematics. The results show that the implemented low-cost system provides valuable insights into the landslide's temporal dynamics.
