FJD Trion V100F – GNSS and LiDAR Fusion Surveying System
The FJD Trion V100F combines GNSS surveying, 3D LiDAR scanning, cameras and IMU in one device. It supports continuous data capture in open, obstructed and GNSS-limited environments, helping surveyors capture points, lines, surfaces and volumes more efficiently on road, bridge, tunnel, mining and other complex engineering projects.SureFix keeps pole-based measurement going as you move from open sky into nearby GNSS-limited areas, with a typical accuracy of ±5 cm within a 20 m radius. For safer non-contact measurement, select targets from captured images for LiDAR-based coordinate measurement within 20 m (±5 cm typical), measuring trench edges, wall corners, areas beneath bridges and slope boundaries without approaching them.Scan tunnels, culverts and slopes for cross-sections and volumes in a single pass, and get stockpile and earthwork volume results directly in the field with FJD Trion Survey. Point clouds, measurements and analysis are then processed in FJD Trion Model. Benefits GNSS, LiDAR, cameras and IMU in one field instrument. Keep measuring in GNSS-limited areas with SureFix (±5 cm typical within 20 m). Measure hazardous or hard-to-reach points without contact. Get cross-sections and volumes on site with FJD Trion Survey.
