Compact RTK GNSS Receivers for Efficient Field Surveying
FJD Trion V4e Series
Choose between the FJD Trion V4e and V4e Pro to match your surveying workflow. Both deliver centimeter-level GNSS RTK positioning in a compact 320 g design, while the V4e Pro adds IMU tilt compensation and integrated laser measurement for faster pole-free point collection.
One Series. Two Surveying Solutions.
The FJD Trion V4e Series combines high-precision GNSS positioning with a lightweight, field-ready design. The standard V4e provides a compact solution for accurate RTK mapping and data collection, while the V4e Pro adds advanced tilt and laser measurement capabilities for more demanding surveying tasks.

STANDARD VERSION
FJD Trion V4e Mini RTK Receiver
The V4e provides a compact and efficient RTK GNSS solution for professionals who need accurate positioning without carrying a larger surveying receiver. With 1,408 GNSS channels and centimeter-level RTK positioning, it is designed for everyday mapping, field data collection, and precision positioning tasks.
Designed for Efficient RTK Mapping
The lightweight 320 g receiver is easy to carry throughout the workday. Its compact design, IP67 protection, and up to 12-hour battery life make it suitable for field environments where portability and reliable positioning are important.
- 1,408-channel GNSS receiver
- Centimeter-level RTK positioning
- Compact 320 g design
- Up to 12 hours of battery life
- IP67-rated protection
- Suitable for mapping and field data collection
PROFESSIONAL VERSION
FJD Trion V4e Pro Mini RTK Receiver
The V4e Pro builds on the V4e platform with integrated IMU tilt compensation and laser measurement. Instead of requiring the receiver to remain perfectly vertical over every point, the V4e Pro allows users to collect points at different angles, helping improve efficiency when surveying difficult or hard-to-reach locations.
IMU Tilt Compensation
Built-in IMU technology enables tilt-compensated surveying without requiring the receiver to remain perfectly upright. The V4e Pro supports measurement at angles of up to 60°, helping users collect points more efficiently in real-world field conditions.
3D error ≤ 2.5 cm
3D error ≤ 3.5 cm
Integrated Laser Measurement
The integrated green laser allows the V4e Pro to measure points without placing the receiver directly over the target. This pole-free workflow is especially useful for corners, edges, obstacles, and other points that may be difficult to access directly.
Maximum laser measuring range
Laser ranging accuracy
Class 2M laser
V4e PRO
Pole-Free Surveying for Hard-to-Reach Points
Combining RTK positioning, IMU tilt compensation, and integrated laser measurement, the V4e Pro provides a more flexible way to collect points where traditional pole-based measurement can be inconvenient.
Point & Measure
Aim toward the target point and collect measurement data without positioning the receiver directly over the point.
Measure at an Angle
Tilt compensation helps maintain efficient data collection when the receiver cannot be held perfectly vertical.
Reach Difficult Points
Laser measurement helps capture points around obstacles, edges, and other difficult-to-access locations.
High-Precision GNSS Performance
* RTK accuracy specifications are based on FJD Trion published specifications and may vary depending on satellite visibility, correction source, atmospheric conditions, baseline length, multipath, and field conditions.
Built for the Field
Both V4e versions are designed for professionals who need reliable positioning equipment that is easy to carry and operate throughout a working day.
320 g Lightweight Body
Compact enough to carry easily between measurement points and field sites.
Up to 12-Hour Runtime
Designed to support extended field work with a single charge.
IP67 Protection
Built to withstand dust and water exposure encountered in outdoor work.
1.2 m Drop Resistance
Designed to handle the demands of everyday field use.
