FJD Trion V100F RTK GNSS Receiver with SLAM LiDAR

FJD Trion V100F RTK GNSS Receiver with Integrated SLAM LiDAR

The FJD Trion V100F is a professional GNSS and LiDAR surveying system designed for land surveying, construction, civil engineering and infrastructure mapping. Combining centimetre-level RTK GNSS positioning with 3D LiDAR scanning, cameras and an inertial measurement unit, it allows surveyors to collect individual coordinates and detailed spatial information using the same instrument.

Conventional RTK surveying is useful for measuring individual points, but complex sites often require additional information about surrounding terrain, structures and inaccessible surfaces. The Trion V100F brings these workflows together. Surveyors can measure points in the usual way, scan an area while walking and use camera-assisted measurements for selected targets that are difficult or unsafe to approach.

With a 32-channel LiDAR scanner, 60 m maximum scanning range, 60° IMU tilt compensation and SureFix technology for GNSS-limited conditions, the V100F is particularly suited to road construction, utility trenches, bridges, tunnels, mining and earthwork projects.

RTK GNSS Surveying with Centimetre-Level Accuracy

At its core, the FJD Trion V100F is a professional multi-constellation RTK GNSS receiver. It supports GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC and SBAS signals, helping surveyors maintain reliable satellite observations across different working environments.

The receiver provides specified RTK accuracy of 8 mm + 1 ppm horizontally and 15 mm + 1 ppm vertically under reference conditions. This makes it suitable for common surveying tasks such as recording ground points, measuring site boundaries, collecting construction features and establishing coordinates for engineering projects.

Position updates are available at rates up to 20 Hz. The receiver also supports static surveying, post-processed kinematic positioning and compatible PPP workflows, giving professional users several options for managing positioning data.

Actual GNSS accuracy depends on satellite visibility, correction quality, environmental conditions and surveying procedures. Independent control measurements remain important for projects requiring verified coordinates.

Integrated 3D SLAM LiDAR for Fast Spatial Capture

The V100F features a 32-channel LiDAR scanner with a 360° horizontal and 62° vertical field of view. Its laser measurement range extends to 40 metres on surfaces with 10% reflectivity and 60 metres on surfaces with 80% reflectivity.

Using SLAM technology, the system can capture a three-dimensional representation of the surrounding environment as the operator walks through the site. Instead of measuring every individual feature separately, surveyors can record the visible geometry of slopes, roads, walls, buildings, tunnels and other structures in a continuous scanning session.

For construction and engineering teams, this provides a practical way to document existing site conditions and collect data for cross-sections, surface models and volume calculations. The scanning system has a typical LiDAR survey accuracy of ±5 cm at 20 metres under specified conditions, which should be considered separately from its RTK point positioning accuracy.

When GNSS reception is available, positioning information can be combined with scanning data to produce georeferenced point clouds in the project coordinate system. When satellite reception is unavailable, the scanner can also work in a local coordinate system using SLAM, with appropriate registration or control required if georeferenced results are needed.

SureFix Technology for Areas with Limited GNSS Reception

One of the distinguishing features of the FJD Trion V100F is SureFix, a surveying function designed to support measurements when satellite reception becomes restricted.

On construction sites, GNSS signals may be obstructed by bridges, buildings, retaining walls or surrounding terrain. These conditions can interrupt conventional RTK measurements, particularly when surveyors need to record points close to large structures.

SureFix combines the instrument’s positioning and spatial sensing capabilities to maintain measurement continuity when moving from suitable GNSS conditions into nearby obstructed areas. The manufacturer specifies typical SureFix accuracy of ±5 cm within a 20 m radius under defined conditions.

For example, a surveyor working beside a bridge can begin in an open area with reliable GNSS reception and continue collecting selected points closer to the structure using the supported SureFix workflow. This can reduce the need to switch immediately to a separate surveying instrument.

SureFix is not a replacement for conventional RTK under all conditions. Its performance and operating range depend on correct initialization, the surrounding environment and the measurement procedure.

60 Degree IMU Tilt Compensation for Easier Point Measurement

The integrated IMU enables tilt-compensated GNSS surveying at pole angles up to 60°. This allows surveyors to measure points without holding the surveying pole perfectly vertical for every observation.

In everyday fieldwork, tilt compensation is useful when measuring corners close to walls, points beside fences, trench edges and other locations where positioning the pole vertically would be inconvenient.

The specified tilt-compensated positioning accuracy is 8 mm + 0.6 mm per degree of tilt RMS under reference conditions. The instrument uses its orientation measurements to compensate for the position of the pole tip, helping operators work more naturally around obstacles.

For construction workers and surveyors who collect many points throughout the day, this can make point measurement faster and more convenient. As with all tilt-compensated surveying, suitable initialization and field checks are important for reliable results.

Camera-Based Measurement for Hard-to-Reach Points

The FJD Trion V100F includes a 12 MP surveying camera, two 12 MP colour cameras and a separate 2 MP bottom camera. These sensors provide visual information for field measurements, spatial capture and point cloud colourisation.

For selected non-contact measurement tasks, surveyors can identify targets in captured imagery and use the system’s LiDAR measurements to determine their coordinates. The manufacturer specifies typical accuracy of ±5 cm within a 20 m working distance for the supported LiDAR-based visual measurement workflow.

This is useful for features such as wall corners, trench boundaries, bridge elements and slope edges that may be difficult or unsafe to reach directly with a surveying pole.

Rather than walking to every point, the operator can capture appropriate visual and laser information from a safer or more convenient position. Measurement results depend on target visibility, scanning geometry and the supported software procedure.

Surveying and 3D Scanning in One Field Workflow

The V100F is particularly useful for projects that require a combination of individual RTK measurements and detailed 3D surface information. Operators can work with conventional survey points when only coordinates are required and switch to LiDAR scanning when the shape of an area needs to be documented.

For example, a road construction team can measure important control points using RTK, scan an embankment or excavation with LiDAR and prepare cross-sections or earthwork calculations from the captured data.

The scanner can be initialized in an area with reliable GNSS reception before entering more restricted environments. This supports georeferenced scanning where the selected workflow and site conditions allow. For indoor or underground areas, scanning can continue using a local coordinate system, with additional registration or control used when necessary.

Combining these measurement methods helps reduce equipment changes during complex surveying projects while providing a broader record of existing site conditions.

Cross-Sections and Volume Calculations in the Field

For earthwork and civil engineering projects, capturing surface geometry can be more useful than measuring a limited set of individual elevation points. The V100F allows operators to scan stockpiles, slopes, excavations and other terrain features and use the resulting spatial data for further analysis.

Through FJD Trion Survey, users can work with supported measurements, cross-sections and on-site volume calculations. This is particularly relevant for contractors who need to document material quantities, check excavation progress or assess terrain changes during construction.

For example, a surveyor can scan a stockpile or excavation area, review the captured surface and prepare a volume calculation using an appropriate reference surface. The accuracy of the calculated result depends on scan coverage, control, processing and the selected calculation method.

The ability to capture and review this information in the field can help identify missing data before leaving the project location.

Integrated UHF Radio and Flexible RTK Corrections

The FJD Trion V100F includes a built-in UHF radio for supported RTK base and rover communication. The radio operates within region-dependent frequency bands of 410–470 MHz or 902–928 MHz and provides up to 2 W transmit power.

The manufacturer specifies a typical communication range of 6–12 km, with up to 16 km possible under optimal conditions. Actual radio performance depends on terrain, antenna installation, interference and local operating restrictions.

The receiver also supports mobile network connectivity, Wi-Fi, Bluetooth and NFC. These communication options allow surveyors to connect compatible field controllers, correction services and project workflows.

With support for industry-standard correction and positioning data formats, including RTCM, NMEA and RINEX, the V100F can be incorporated into a variety of professional GNSS workflows. Radio frequency availability and compatibility should be confirmed for the intended country and correction setup.

Integrated Cameras and Colourised Point Clouds

Alongside the LiDAR scanner, the V100F includes cameras that support visual documentation and the generation of colourised point clouds. The two 12 MP colour cameras capture imagery that can be associated with laser measurements, making scanned objects easier to recognise during review.

Colourised point clouds are useful when documenting buildings, roads, construction features and other visible objects. Instead of viewing only geometric points, users can see photographic colour information that provides additional context about the scanned environment.

For engineering and inspection projects, this can make it easier to identify specific structures, understand site conditions and communicate findings with colleagues who do not regularly work with raw LiDAR data.

Designed for Demanding Surveying Environments

The FJD Trion V100F weighs approximately 1.75 kg and has dimensions of 215 × 130 × 120 mm. Its integrated construction combines surveying, scanning and imaging hardware in a compact instrument suitable for professional fieldwork.

The enclosure is rated IP65 for protection against dust and water jets and IK08 for mechanical impact resistance. The specified operating temperature range is -20°C to +55°C, making the receiver suitable for a variety of construction and outdoor surveying environments.

Battery endurance depends on the selected operating mode. The manufacturer specifies up to 22 hours of typical UHF or 4G RTK rover operation and up to 5 hours of LiDAR scanning. The 74 Wh rechargeable battery supports 45 W PD charging, with a specified charging time of approximately 3.5 hours.

With 450 GB of internal storage, the V100F can record substantial amounts of scanning and survey data. Operators should plan available storage and battery capacity according to the project size and selected capture settings.

Applications in Surveying Construction and Infrastructure

Land Surveying and Topographic Mapping

Surveyors can use RTK GNSS for collecting individual ground points and use LiDAR scanning to record the geometry of surrounding terrain. This combination is useful when a project requires both discrete survey coordinates and a more detailed representation of the existing surface.

Road Construction and Civil Engineering

Construction teams can use the V100F to measure control points, document road surfaces, capture embankments and prepare cross-section information. The ability to switch between RTK and scanning is particularly useful on construction projects where ground conditions change throughout the working area.

Utility Trenches and Underground Infrastructure

For trench surveys, the scanner can capture visible excavation geometry and surrounding structures. Camera-assisted measurement can also help record selected edges and corners from a more convenient position. This information can support as-built documentation and excavation analysis.

Bridges and Viaducts

GNSS reception is often restricted beneath bridges or close to large structures. The combination of SureFix technology and LiDAR scanning provides additional measurement options in these environments, helping surveyors record selected points and visible structural geometry.

Tunnels and Underground Mapping

The V100F can capture 3D point clouds in GNSS-denied environments using its LiDAR and SLAM workflow. This can support tunnel documentation, cross-section measurement and geometric analysis. Where project coordinates are required, suitable initialization and survey control are necessary.

Mining Quarries and Earthworks

Mining and earthwork professionals can use the scanner to document accessible excavations, stockpiles, slopes and terrain surfaces. Processed point clouds can support volume calculations, surface comparisons and project monitoring.

GIS and Infrastructure Asset Mapping

GIS professionals can use georeferenced survey points and processed point clouds to document infrastructure assets, visible features and terrain. The collected spatial information can support mapping projects and further analysis in compatible GIS and engineering applications.

FJD Trion Survey and Trion Model Software

The V100F works with FJD Trion Survey for field data collection and surveying operations. The software supports GNSS measurements, LiDAR scanning, coordinate system management and field workflows involving cross-sections and volume calculations.

For office-based processing, FJD Trion Model provides tools to work with collected point cloud data, review measurements and prepare information for surveying, construction and engineering deliverables.

Depending on the selected workflow, scanning data can be processed into georeferenced point clouds and transferred into compatible applications using supported export formats such as LAS. The V100F also supports standard GNSS data formats for positioning and correction workflows.

Available advanced processing functions, software licenses and cloud services should be confirmed for the selected system configuration.
