During the long life cycles of railway infrastructure, railway structures and surrounding landscape and objects can move or change. Rail operators use monitoring to understand the dynamics of natural and man-made objects over time.

Trimble Monitoring Systems provide precise information on the subtle, long-term motion of landforms, walls, tunnels, supports and other slow-moving structures. Fully-automated Trimble monitoring systems use Trimble GNSS and Total Stations to gather information over extended periods. If your project doesn't require continuous monitoring, you can use Trimble campaign monitoring to conduct precise, periodic measurements of key points.

Trimble systems can measure rapid motion to help understand the behavior of bridges and structures under dynamic loads. Trimble rapid motion detection technology combines GNSS and advanced computations to capture small changes that result from wind, traffic or other forces on a structure.

Some monitoring projects involve steep slopes, tunnels or other distant or difficult locations. Trimble sensors and targets can be permanently installed, eliminating the need to make frequent trips to remote or hazardous areas. Sensors can be controlled and updated from a convenient location.

Trimble 4D Software is the hub of your Trimble monitoring system. It controls the sensors, manages data and provides computations and results. You can use sophisticated Trimble routines to analyze your data and create customized reports. The SQL monitoring database can be accessed by external software for specialized computations. The Trimble Web Module allows designated project stakeholders to view system status and output via secure Internet access.
