One for projects.

Locator One

Continuous insight into movement, deformation and settlement, throughout every stage of your project.

Locator One is an autonomous GNSS- and radar-based monitoring system designed for project-based applications in construction, geotechnical engineering, and infrastructure works. By combining high-precision GNSS positioning with radar distance measurements, Locator One delivers reliable 3D displacement data for monitoring settlement, movement, and water levels, helping teams stay informed and in control.

Projects move fast. Your deformation data should too.

During construction and geotechnical projects, change is constant and unexpected situations can arise. Ground conditions shift, slopes can become unstable, structures settle and loads change over time. Without continuous insight, risks can go unnoticed, and planning can become uncertain. Of course, this also provides positive insights: the absence of subsidence over the last 30 days enables more optimal planning of ground additions.

To stay in control, wouldn’t it be ideal to have reliable, automated insight into movement, deformation, and settlement throughout the project, without relying on time-consuming manual measurements?

Locator One provides autonomous monitoring that keeps you informed from the first day of installation through to the final phase of construction.

Flexible deployment and easy installation

Locator One installs quickly on settlement rods or directly on structures, enabling monitoring from the first day of installation. Whether deployed as a single unit or across a larger project area, Locator One scales easily to fit your monitoring needs.

Automated and secure monitoring

Locator One automatically transmits and processes measurements to Parvamoti, Basetime’s cloud platform, delivering validated deformation data without manual effort. All data is encrypted, giving you secure, reliable insights from day one.

Alerts when thresholds are exceeded

Locator One continuously monitors movement and automatically notifies users when predefined thresholds are exceeded. Automatic alerts enable faster response, helping teams manage risk and keep projects safe.

We're here to help your industry.

Locator One is engineered for temporary, high-precision monitoring in dynamic construction settings. Typical applications include:

Settlement Rod Monitoring

Installed on settlement rods or nearby structures, Locator One tracks vertical movement and soil compaction over time. The integrated radar sensor enables precise measurement of ground layers and residual settlement during fill operations.

Water Level Monitoring

Using integrated radar distance measurements, Locator One can continuously monitor surface water levels in canals, rivers, or basins.

Ground Movement Monitoring

Locator One monitors ground movement throughout earthworks and excavation activities, helping project teams detect unexpected shifts early and maintain control on site.

Landslide & Slope Stability Monitoring

Slope monitoring before and after landslide events, providing continuous 3D displacement insight for risk assessment and mitigation.

how does locator one work?

Locator One provides your project with accurate 3D movement tracking.

Locator One is built for reliable outdoor environments and can operate autonomously using solar power. It continuously determines its position with high-precision GNSS measurements, providing accurate three-dimensional movement tracking.

An integrated radar sensor measures distances to the ground or water surface, allowing direct monitoring of settlement and water levels. All measurement data is transmitted via LTE-M to Basetime’s cloud platform, Parvamoti, where it is processed and visualized.

Users can monitor movement remotely and receive alerts whenever predefined thresholds are exceeded, ensuring consistent oversight throughout the project lifecycle.

Proven precision in the field.

Locator One delivers sub-centimeter accuracy using advanced geodetic processing, giving you confidence in every measurement. GNSS sensors achieve horizontal precision of 2 mm + 0.5 ppm and vertical precision of 4 mm + 0.5 ppm, with long-term trend detection under 1 mm.

Radar sensors measure distances to 1 mm, enabling simultaneous monitoring of structural movement and ground or water level changes. Built for demanding outdoor conditions, Locator One ensures reliable, high-uptime performance across projects of any scale.

“The accuracy of the chosen method exceeded expectations, and it can be concluded that the Basetime system can be used with much higher accuracies than the originally specified specifications, provided that post-processing is done on the highly redundant measurements.”

– Sander Schröder – Manager Innovations, Coenradie BV

“Basetime’s system was the ideal solution for us to implement continuous building monitoring, as we could not establish a connection with the back of the buildings for homogeneous monitoring of both buildings using conventional methods (total station and/or leveling). By combining this technique with vibration sensors, we had the perfect tool to keep an eye on the buildings.”

– Robbert Mathijssen –Municipality of Rotterdam

“The Locator One gives us many insights into the movement of the landslide. It helps us monitor the environment and control the situation.”

– Martina Mittelberger – State Office for Surveying and Geoinformation Vorarlberg, Austria
