The World’s First CO2 Neutral Movement Detection Sensor

An autonomous GNSS-based monitoring system with subcentimeter precision, and time as a fourth dimension.

Making High-Precision Surveying Accessible

Locator One uses GNSS and RADAR sensors to monitor both the vertical movement of the original ground level and the level and thickness of added sand layers.

Along with measuring the settlement of layers, we develop the Locator product to serve other monitoring purposes such as the movement of bridges, harbor quays and dam walls.

Keep an Eye on Every Movement

Locator One delivers accurate and reliable geodetic data through the Basetime dashboard or your preferred information system.

Compared to the traditional method of collecting geodetic observations, the automatic device offers numerous advantages. In addition to giving precise GNSS measurements and measuring the distance to ground with radar, the Locator One guarantees:    


Measures with the precision of 5mm in the Z direction and 3mm in the X-Y direction. An autonomous device that guarantees consistent data and 95% uptime.


Collection and calculation of accurate data on pre-defined timestamps offers prediction of subsidence and settlement allowing for precautionary actions.


Improves construction site safety by eliminating unnecessary human involvement, in-person site visits and use of 4X4 cars on terrains.


Powered by solar energy and a super capacitor, Locator One functions autonomously and eliminates the need for maintenance rides, reducing CO2 during operations.

How does the device work?


A fleet of Locator One devices are mounted on settlement rods to determine the height of the baseplates, which are positioned at the original ground level.


The devices send their observations and metadata through an IoT network to our cloud. After geodetic adjustments and calculations, the data is delivered.


Results are displayed on the Basetime dashboard, or preferred environment through an API. In joint consultation, we adapt the data to the contractors working method.


In addition to providing you with innovative solutions, we offer consultancy to optimize your productivity. Our team possesses almost 15 years of experience and has successfully completed 100+ projects in the mathematical geodesy and GNSS domain. This is complemented with a leadership position in the field of sensors and IoT.

Settlement Rods

Locator One is our first device, engineered to autonomously monitor your construction grounds. By placing a fleet of devices atop already placed settlement rods, deformation observations are collected resulting in high accurate data delivered to the Basetime dashboard or a preferred information system.

For Who?

Governmental authorities, construction companies, maritime corporations and geodetic and geotechnical engineers that use hundreds of devices for monitoring dikes, dredging grounds, and construction terrains.


  • Autonomous, precise GNSS-based monitoring system
  • Backend database, including geodetic and other statistic algorithms, improving the precision of measurements
  • Basetime dashboard or via API delivering the data right to your desk


Basetime Locator One uses a GNSS sensor to monitor and present the vertical movement of the original ground level and RADAR sensor to measure the height and thickness of the added sand layer, by calculating the offset between the ground and the sand package. The automated sensor measures the exact position of the top of a settlement rod with the precision of – at most – 5mm in the Z direction and 3mm in the X-Y direction.

By using these observations, we calculate and provide the accurate information you need, such as the settlement of the original ground level and the added sand layers.
