FJ DYNAMICS RANGE · HYBRID LIDAR SCANNER
FJD Trion T1
FJ Dynamics' first hybrid mobile and stationary LiDAR scanner. Walk the whole site in mobile mode, then set it on a tripod wherever accuracy matters: 4 mm at 10 m. One device for the whole project.

One scanner for the whole project
Efficiency or accuracy: no need to choose any more. Cover large sites in mobile mode, then switch to terrestrial mode for critical areas. Both surveys can be processed separately or merged into a single point cloud.

COVER THE SITE
Mobile mode
• Relative accuracy ≤ 1 cm
• Range from 0.5 to 120 m
• Handheld, on a vehicle or on a drone
• Scan sessions of up to 1 hour

REFINE WHAT MATTERS
Terrestrial mode
• Relative accuracy of 4 mm at 10 m and 8 mm at 30 m
• Range from 0.5 to 60 m
• 30 s per station, or 2 min in high density
• Ideal where mobile SLAM is less reliable
Integrated by design

Multi-constellation, 8 mm + 1 ppm horizontal, PPK mode for post-processing.
4 cameras
Three 48 MP imaging cameras for 360° panoramas and one 1080p vision camera.
1.65 kg, modular
A light unit, easy to carry and reconfigure, with an accessory mount.

MOBILE MODE
Mobile mode builds the framework of the survey
See your coverage
Real-time colourised point cloud in 2D or 3D: spot missing areas before you leave the site.
Scan for longer
Continuous sessions of up to 1 hour to cover large areas in one go.
Pick up where you left off
Survey in stages: re-align on an area already scanned and the software merges the data, with no manual registration.
From ground to air
Handheld, on a vehicle or on a drone, to cover roads, infrastructure, forests and large sites.
TERRESTRIAL MODE
Terrestrial mode adds the detail
Choose between speed and density at each station, with the same nominal accuracy.
30 s
Fastest station
2 min
High density
4 mm
Accuracy at 10 m
Every station linked
Multi-sensor SLAM records the relative position of stations as you move, for faster registration during processing.
The site, not just the scan
Three 48 MP cameras produce 360° panoramas and richly colourised point clouds.

Results tailored to every need
Process mobile and terrestrial surveys separately, or merge them into a single point cloud, depending on whether the project calls for overall coverage, precise local detail, or both.
Cover and review the whole site
Mobile point cloud — ideal for the overall view and site documentation.
Inspect and measure critical areas
Terrestrial point cloud — ideal for local detail and precision measurements.
Combine coverage and detail
Merged point cloud — ideal for full review and project delivery.

Which FJ Dynamics scanner should you choose?
Trion T1
The hybrid choice: mobile coverage and millimetre accuracy on a tripod in a single device.
Trion S2
Large sites in mobile mode: up to 300 m range, and mountable on a drone, vehicle or quadruped robot.

Discover the FJD Trion X1 →FJD Trion T1 frequently asked questions
What is the difference between mobile mode and terrestrial mode?
In mobile mode, you scan while walking (or on a vehicle or drone) to cover a large site quickly, with relative accuracy ≤ 1 cm. In terrestrial mode, the T1 sits on a tripod for more accurate fixed stations: 4 mm at 10 m and 8 mm at 30 m.
Can the two surveys be combined?
Yes. Mobile and terrestrial point clouds can be processed separately or merged into a single cloud in FJD Trion Model. Multi-sensor SLAM records station positions as you move, which speeds up registration.
How long does a station take in terrestrial mode?
30 seconds for the fastest, up to 2 minutes for higher density, with the same nominal accuracy.
Is the T1 georeferenced?
Yes. The built-in RTK module (BDS, GPS, GLONASS, Galileo, QZSS) achieves 8 mm + 1 ppm horizontal, and PPK mode allows post-processing when real-time correction is not available.
What is the battery life?
Around 3.5 hours with two battery handles, at a power draw of 24 W. DC power is also possible.
Can I see the T1 in a demonstration?
Yes. DART Solutions runs demonstrations at your site in both modes and trains your operators on the scanner and on FJD Trion Model.
