FJD Trion V4E / V4E Pro — Mini RTK GNSS Receiver

The FJD Trion V4E It is an ultra-compact RTK GNSS receiver alone Weighing 320 g , it's designed to offer professional centimeter-accurate positioning with maximum portability. Ideal for surveyors, technical offices, construction sites, and field surveys, it allows for "plug & survey" operation: turn on, acquire, and deliver, without lengthy setup or bulky equipment.

Uncompromising Centimetric Precision

With 1408 multi-constellation and multi-frequency channels, the V4E supports GPS, BDS, GLONASS, Galileo, QZSS and SBAS for global satellite coverage. RTK accuracy reaches H ≤ 0.8 cm + 1 ppm And V ≤ 1.5 cm + 1 ppm (RMS), with initialization in less than 5 seconds and 99.9% reliability. Signal reacquisition occurs in less than 1 second, ensuring operational continuity even in difficult environments.

The Pro Version: Integrated IMU and Laser

There Pro version adds the TILT compensation via integrated IMU , which allows you to measure with the pole inclined up to 30° without the need for levelling. green laser meter integrated allows to detect physically inaccessible points with a 3D error ≤ 3 cm at 3 m distance.

Advanced Connectivity

The V4E supports dual-mode Bluetooth 4.0 with a range of 5m for connecting to the controller. In dual-mode Base Station , also integrates Wi-Fi 2.4G with a capacity of up to 300 m , to transmit RTK corrections without external cables or networks.

Robustness and All-Day Battery Life

Certificate IP67 and resistant to drops up to 1.2 m, it works for over 12 hours Charging in ≤ 3 hours via USB-C. It can be used while charging via a power bank without interruption. The operating temperature ranges from -20°C to +60°C.

Application Scenarios

• Topographic and cadastral survey
• Construction and outdoor BIM
• Utilities, infrastructure and public works
• Road survey and monitoring
• Forestry, agriculture and automatic driving
• Robotic and automation integration

FJD Trion V4E LiDAR Kit — Mobile 3D Scanner with Integrated RTK

The FJD Trion V4E LiDAR Kit is a mobile 3D scanning solution that combines the Trion V4E's RTK GNSS positioning with a professional LiDAR sensor to generate Real-time georeferenced point clouds . It's the ideal choice for facade surveys, outdoor BIM, and underground utility mapping, where a 3D model that can be immediately used in CAD/BIM/GIS workflows is needed.

One Kit, Two Configurations

• V4E LiDAR Combo (with GNSS): georeferenced point clouds with real coordinates for external surveys
• V4E LiDAR (without GNSS): optimized for indoor surveys, lightweight and with quick setup

Dense and Real-Time Scanning

The sensor acquires 154,000 points per second with 360° horizontal FOV and -10° to +60° vertical FOV. The accuracy of the point cloud is 1 cm relative / 3 cm absolute post-processing, and 5 cm in real time during acquisition. The detection range is up to 50 m (target at 90% reflectivity).

Portability and Operational Simplicity

With about 890 g of weight and over With 5 hours of battery life , it's designed for intensive operating sessions without tiring the operator. Setup takes less than 60 seconds and is compatible with iOS (iPhone 15+) and Android (Galaxy S20+), with over-the-air firmware updates.

Flexible Workflow

The data is processed in the field on tablets via FJD Trion Model , generating point clouds, BIM-ready files and meshes. Synchronization with FJD Trion Cloud enables rapid sharing and review across distributed teams.

Application Scenarios

• Survey of facades and architectural heritage
• Outdoor and as-built BIM
• Mapping of underground utilities and infrastructure
• Interior surveys (offices, technical rooms, warehouses)
• Construction site and progress monitoring
