The GNSS Meter leverages Worldsensing’s field-proven Loadsensing technology, which ensures long-range radio connectivity without dependence on internet or cellular networks.

Designed for scalability and robustness, the GNSS Meter integrates seamlessly with the rest of the Loadsensing portfolio that stream data from other geotechnical sensors such as piezometers, inclinometers, and extensometers, allowing comprehensive, automated monitoring.

Millimetric precision

Achieves sub-centimeter precision (down to 2mm) with hourly position updates, offering two aggregation levels: 6h and 24h.

Flexible configuration options

Can function as a base or rover, with field tools for radio link testing.

Advanced edge data-processing

Position quality and system performance statistics are transmitted via radio and available in CMT.

Wireless, autonomous, low-power

Battery-powered with D-size batteries, providing over 3 years of autonomy.

Integrated tiltmeter and environmental sensors

Measures vertical shifts in structures and provides data when RTK conditions are unavailable.

Report displacement

Calculate vertical, and horizontal (E/W, N/S, absolute) displacements from the initial position within CMT.

Main Applications

The GNSS Meter is designed for cross-industry applications, offering millimetric precision in areas such as slope stability, settlement, and subsidence monitoring. It is ideal for dense point monitoring or as a complement to inground sensors like inclinometers and extensometers, as well as geospatial techniques like satellite InSAR, ground-based radar, and total stations, enhancing overall data reliability and robustness.
