TEDAMOS GNSS
GNSS monitoring enables precise three-dimensional tracking of movements in structures and terrain.
GNSS (Global Navigation Satellite Systems) is a globally available technology for precise positioning using satellite signals. It includes systems such as the US-based GPS, the Russian GLONASS and Europe’s Galileo.
Since 2015, we have been operating our own commercial GNSS monitoring stations, with more than 75 systems currently deployed across Switzerland. The sensors transmit raw data hourly via the GSM mobile network to TEDAMOS servers, where it is processed automatically using the proven Bernese GNSS Software. By applying differential GNSS techniques, we achieve measurement accuracies in the low millimetre range, depending on the distance to the reference station. Reference data is provided either by our own permanently installed reference stations or by the AGNES stations operated by swisstopo.
This enables the continuous monitoring of movements in geological formations, landslide-prone slopes, glacier areas and structures such as cable cars, bridges, dams and high-rise buildings. The monitoring data provides the basis for automated warning systems based on absolute displacements or movement rates per day or week.
Key Benefits at a Glance
- Millimetre-level 3D positioning accuracy
- Long-term monitoring without loss of accuracy
- Maintenance-free operation based solely on satellite signal reception
- Year-round operation, independent of snow, fog or vegetation
- No line of sight required between monitoring points
- Compact all-in-one solution with simple installation
By the way: TEDAMOS GNSS sensors were specifically developed for harsh alpine environments. Thanks to the solar panels integrated around the pillar design, sufficient energy is generated to support GNSS monitoring even during winter months and on shaded mountain slopes.
