Key Benefits

Small Size, Big Power
Deliver centimeter-level accuracy with ±1.5 cm static precision. It supports 1408 channels and covers all GNSS constellations, including GPS, BDS, GLONASS, Galileo, QZSS, and SBAS. Weighing only 320g, the V4E offers broad compatibility with popular correction services, supporting NTRIP connectivity with RTCM 2.3, RTCM 3.x, and CMR.
No Pole, No Problem
Compensate for tilt angles up to 30° (PRO version) with a built-in IMU, so you don't need to hold it perfectly straight. This gives you ≤3cm accuracy at a 3m distance without a leveling rod. Its onboard LiDAR rangefinder in the PRO version also achieves ±3mm precision at a 10m distance for precise point targeting.


Built Tough for All-Day Efficiency
Stay powered up for the entire workday. It can run for over 12 hours and takes less than 3 hours to charge. You can even keep the V4E working while charging it with a power bank, so your work is never interrupted.
Protected. Durable. Reliable.
With IP67-rated protection against water and dust, and 1.2-meter drop resistance, the V4E is built to withstand tough environments. It keeps working reliably even when exposed to dust or accidental drops, ensuring consistent accuracy for your outdoor projects.


EASIER ACCESS TO FJD TECH ECOSYSTEM
Access the FJD ecosystem quickly for a smooth workflow from field to machine. The GNSS data you collect with the V4E in the field can be directly used by FJD's farming autosteering systems, robotic mowers, and other smart devices for automated tasks. You don't have to convert the data, allowing you to work faster and reduce mistakes.
* Beyond the FJD ecosystem, its open design also supports customization to fit your unique needs.
