Trimble 4D Control

Monitoring Software

Detect displacement or movement in natural and manmade structures


A monitoring installation lets you detect displacement or movement in natural and manmade structures. It provides the data you need to understand the speed, direction and magnitude of any motion. The software is the core of your monitoring project. It controls the measurements, manages and analyzes the data, and provides decision support.

Getting started is easy with scalable monitoring solutions from Trimble. Trimble 4D Control provides analysis and management tools to help you start small and grow. As your expertise in monitoring increases, you can easily expand from postprocessed deformation monitoring campaigns all the way to real-time systems that manage your projects and alert the operator of significant motion events.

Software Components

The Trimble 4D Control software provides different components for different monitoring requirements. Each component offers a number of functions for specific monitoring operations such as instrument control, data collection and data processing.

The web front-end of Trimble 4D Control offers comprehensive tools for data visualization, data analysis, event logging and alarming. It is optimized for fast response and live data visualization in map and custom views. It contains simple, fast charting facilities and color coded scatter plots for quick data analysis as well as high-level analysis tools for detailed inspections.

Offers multiple real-time GNSS processing engines for different monitoring tasks including a server-based RTK engine. All of them require real-time data connections to the GNSS receivers. Supported data formats are the Trimble Real-Time format, CMRx, BINEX, RTCM 3 and NMEA. Download and/or create raw data files from a GNSS receiver using a real-time connection or remote download. Raw data files can be processed automatically according to a schedule. Multiple processing sessions with different observation times, data rates, etc. can be run in parallel.

Contains a module which logs RINEX, T01 or T02 files on the server and uploads them to a Trimble-hosted web service. It also receives a correction data stream from a Trimble server to process positions in real-time. Your observation file will be processed against data collected by the service and a processed vector will be transferred back to your T4D server. No base station is required.

Contains all modules which are required for an automated, real-time monitoring system with total stations. Perform your site setup, configure the scheduler and the system will operate the instrument and take the observations. It enables you to process and analyze field data collected by using a TSC 3 or TCU. This either can be done with the Measure rounds function of Trimble Access General Survey or with the Trimble Access Monitoring module. It includes deformation analysis, reports and charts.

Supports all kinds of geotechnical sensors and weather stations.

Combines accelerometer and GNSS data in a Kalman filter to produce high rate (200 sps) displacement data.

Control Room Web
Trimble 4D Control Room Web allows to monitoring an unlimited number of Trimble 4D Control projects that belong to the same or different installations.

Complete Sensor Management

Trimble 4D Control manages all of your sensors. It measures and stores the data according to schedules that you define. By leveraging GNSS, geotechnical sensors, and surveying instruments and tools, learn how Trimble enables geospatial professionals to customize a monitoring solution to meet the needs of even the most demanding applications.

Trimble GNSS
Trimble GNSS provides long-range accuracy and rapid update rates. Compact and rugged, the Trimble NetR9 GNSS Reference Receiver is capable of tracking all existing and planned GNSS signals. Now available in a fourth configuration, the new Trimble NetR9 Ti-M receiver is supported for real-time monitoring applications.

Trimble Seismic Systems
The data from Trimble recording instruments for hazard mitigation and earthquake research can be put directly into Trimble’s Monitoring Solution. Trimble 4D Control now supports peak acceleration using seismic hardware. This data is stored in the Monitoring database where alarming and visualization can be controlled through the web interface.

Trimble Kestrel System
The seismogeodetic system integrates seismic recording with GNSS geodetic measurements in a single compact, ruggedized package to create high-rate (200 sps), full epoch-to-epoch measurement integrity, real-time displacement with sufficient accuracy and very low latency for infrastructure monitoring and precise scientific applications with a focus on a wide spectrum of natural hazard mitigation applications.

Trimble Total Stations
Trimble 4D Control provides support for the S7, S8 and S9 Total Stations with FineLock technology for precise monitoring of points up to 2,500 meters away with one centimeter accuracy. Designed to handle demanding jobs and difficult environments, Trimble Total Stations are ideal for engineering and monitoring applications that depend on fast, accurate measurements.

Trimble 4D Control supports a broad array of sensors, 3rd-party geotechnical and meteorological sensors.
