Voyager OMA Intelligence

Powered by Observer Automation

Designed for bridges, buildings, dams, mines, towers, and other critical infrastructure, Voyager OMA Intelligence enables engineers and asset owners to track how modal properties evolve over time, detect significant changes in structural behavior, and support faster maintenance, inspection, and safety decisions.

Overview

The Voyager Operational Modal Analysis Intelligence is a new, advanced module incorporated into the Digitex SHM systems that automatically transforms live or scheduled structural and vibration monitoring data into engineering-grade Operational Modal Analysis results.

Powered by Observer Automation, the module runs periodic or near real-time OMA analyses, generates modal parameters, provides 3D mode-shape visualizations, and MAC verification matrices. Additionally, you’ll find availability of OMA info charts, signal-processing outputs, and professional reporting — all accessible through the secure Voyager web interface.

Digitex Systems designed it for all critical civil infrastructure – from bridges, buildings, and dams to mines, towers, and other critical infrastructure. The Voyager OMA Intelligence enables civil engineers and asset owners to track how modal properties evolve, detect significant changes in structural behaviour, and support faster maintenance, inspection, and safety decisions.

Voyager Operational Modal Analysis Workflow

Voyager collects and stores data from the Digitex Sentry devices installed on the structure. Then, in the background, the Observer Automation processes the selected time windows, performs Operational Modal Analysis and signal-processing tasks. Lastly, it generates the results and returns them to the Voyager for real-time user review and all other tasks through the Voyager web interface. 

Below is the exact workflow of how you can use our MEMS accelerometer vibration sensors and remote vibration monitoring to turn your data into decisions:

You can configure the system to run analyses periodically, near real-time, or based on pre-selected events. For example, you can analyze a bridge every 10 minutes. On the other hand, you can analyze a dam after a significant vibration event, or a building during specific scheduled time windows. Each analysis will produce a structured result package containing OMA outputs, detected modes, verification data, charts, reports, and optional 3D visualizations.

One of the most important features is the modal change tracking. The system compares newly calculated modal results with a baseline reference. Firstly, you can validate this reference through the Operational Modal Analysis results, a selected healthy-state analysis, or another engineering-approved reference condition. Using MAC-based comparison and configurable thresholds, Voyager detects when modal behaviour changes or breaches beyond the acceptable range.

This is especially useful for long-term Structural Health Monitoring. Modal frequencies and mode shapes change due to operational loading, various forms of damage, temperature changes, humidity, aging, stiffness reduction, changes in boundary conditions, or other structural interventions.

By storing every analysis result, Voyager OMA Intelligence allows engineers and vibration monitoring companies to observe these changes over time rather than relying solely on isolated measurements. 

Civil engineers, building managers, and asset owners can easily rely on the Digitex vibration monitoring equipment for these measurements. 

Voyager Operational Modal Analysis Vs. Traditional OMA

Raw acceleration and vibration monitoring records alone can’t immediately tell a civil engineer or an asset owner whether the structure is changing, evolving stiffness or a specific mode shape requiring attention.

Through the extraction of modal parameters, the Operational Modal Analysis solves this problem. Practically, it solves all of it – natural frequencies, damping ratios, and mode shapes extracted from ambient or operational vibration monitoring data. Traditionally, this process needs an engineer to manually export data, initialize a specialized software, run OMA methods, validate results, compare modes, do an analysis, and prepare reports. Data is available every few minutes.

All in all, it gives a powerful touch to the whole process. However, during practical and continuous condition monitoring from vibration monitoring devices, it is complex and hard to adjust the model constantly and in real-time. That’s where Digitex Systems’ automated Voyager OMA Intelligence jumps in and makes the whole process smoother and easier, including the verification features.

Simply put, no matter if you use the wireless accelerometer for vibration analysis or any other model, these features will support structural and people’s safety!

Key Capabilities

The Voyager OMA module also preserves the engineering depth of Observer. It means that the users aren’t limited to a simple alarm value. They can open detailed OMA charts, review method-specific outputs, inspect MAC verification, and view 3D mode-shape visualizations.

Additionally, they can check signal-processing results such as FFT, PSD, integration, and correlation, and download professional reports. This gives both high-level vibration monitoring insight and detailed engineering traceability for all the Structural Health Monitoring requirements.

  • Automated OMA from Live Data

    Voyager can execute OMA analyses on scheduled intervals, periodic windows, or selected near-real-time data segments. This will allow the system to continuously evaluate the dynamic behaviour of the monitored structure without requiring the user to manually export data and open it in desktop software.

  • Powered by Observer Automation

    The Digitex analysis engine utilizes the advanced capabilities of the Observer, including OMA methods, signal-processing tools, 3D geometry, modal visualization, MAC verification, and report generation. Simply put, it means that the web platform does not replace Observer — it extends Observer’s engineering power into a fully automated monitoring workflow.

  • MAC-based Change Detection

    The module compares the newly calculated modal results with a reference state. For example, the first validated MAC matrix or baseline OMA result. If the difference exceeds a configured threshold, Voyager marks the analysis as changed and generates a trigger or a notification.

  • Historical Modal Evolution

    Every analysis can be stored and reviewed historically. Engineers can track modal frequencies, damping, MAC values, and mode-shape consistency over days, months, or years. For example, the system can run OMA every 10 minutes and build a long-term chart of the changes of the first MAC matrix or selected mode.

  • 3D Mode-shape Visualization

    Civil engineers can identify modes and connect them with the configured structural geometry, and presented as 3D mode-shape outputs. Additionally, this includes animations or visual exports. In this manner, Digitex Systems gives civil engineers a practical way to understand not only that a change has happened, but also where and how the dynamic behaviour of the structure is changing throughout the whole structural monitoring process.

  • Full Analysis Archive

    Each automatic analysis can be stored with its complete result set: charts, PNG previews, GIF animations, PDF reports, OMA method outputs, verification data, signal-processing results, and database references. In this way, engineers have an auditable historical archive of the monitored structure’s behaviour always at hand.

  • Secure Web Access

    Authorized users can access results through Voyager by using secure credentials and role-based access. Civil engineers, operators, owners, asset managers, and decision-makers can review current and historical analyses without needing direct access to the monitoring computer or Observer desktop environment.
