Two for permanence.

Locator Two

To measure is to know; understand the natural movements and detect anomalies as soon as they appear.

Locator Two is the ideal solution for permanent, autonomous 3D displacement and tilt monitoring of railways, quays, bridges, and critical infrastructure. It detects anomalies early, alerting you when action is needed and helping you prevent risks before they escalate.

Infrastructure always moves. The question is: do you know when it shouldn’t?

Every bridge, railway, and quay wall is in constant motion, expanding, contracting, and shifting under the forces of temperature, traffic, tides, wind force, and time. Most of these movements are expected. The real challenge lies in identifying the subtle deviations that signal risk.

Traditional inspections and periodic surveys offer only snapshots in time. They miss the small, early signs that can prevent costly downtime or even catastrophic failure.

This is where Locator Two steps in…

Fewer site visits

Locator Two enables remote insight into asset location and status, reducing the need for manual checks and on-site inspections. Issues can be identified faster and addressed only when action is truly needed.

Lower operational costs

By minimizing unnecessary site visits, manual labor, and unplanned downtime of the asset, Locator Two helps significantly reduce operational costs while improving efficiency across daily operations.

Lifecycle coverage

From installation and commissioning to operation and decommissioning, Locator Two provides continuous visibility throughout the entire asset lifecycle, supporting smarter decisions at every stage.

We're here to help your industry.

Locator Two is developed for autonomous, high-precision monitoring across railways, harbor quays, bridges, dams, and other critical linear assets where continuous insight into structural movement is essential for a safer working and living environment.

how does locator two work?

Locator Two provides clear insights into structural movement.

Locator Two GNSS and tilt monitoring device mounted on a quay wall near the Erasmus Bridge in Rotterdam, used for autonomous structural movement and tilt monitoring.

At the heart of Locator Two lies the combination of two precision technologies that together reveal the true behavior of structures over time:

GNSS for Absolute 3D Displacement

GNSS continuously measures position in three dimensions, not only how far a structure moves, but in which direction and by how much, presented in a coordinate system of your needs. Over time, it builds a complete picture of normal movement patterns caused by temperature changes, seasonal effects, and other environmental factors. When the structure behaves differently from this baseline, the anomaly is immediately visible.

3D Tilt for Rotational Insight

While GNSS shows where movement occurs by tracking position over time, tilt sensors reveal how a structure moves. They measure small changes in inclination and rotation, helping to detect early deformation or uneven settlement that can indicate the onset of a structural issue.

Measuring GNSS position up till 96 times per day and tilt up to 288 times per day, configured by yourself, you are always in control about your asset.

“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

Parvamoti

Full access to your monitoring data anywhere, anytime.

Together, GNSS displacement and tilt measurements provide a complete understanding of how your structures behave, across seasons, loads, and daily operations. All data is automatically transmitted to Parvamoti, the Basetime cloud platform, where it is processed into clear trends, visualizations, and alerts. Your team can review asset performance from a phone or laptop, detect anomalies early, and respond quickly, without site visits or manual data collection. When movement exceeds defined thresholds, alerts are generated so you can focus attention where it’s needed most.
