FJD Trion™ V4E Mini RTK Receiver

FJD Trion™ V4E Mini RTK Receiver

The FJD Trion V4E Mini RTK Receiver breaks the boundaries of traditional GNSS receivers with handheld convenience and portable precision. Weighing only 320g, the V4E delivers centimeter-level positioning without centering rods, making it perfect for individuals, teams, and professionals on the go. Easy to use and budget-friendly, it can instantly unlock the power of high-accuracy surveying.

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. With IP67-rated protection against water and dust, and resistance to drops from 1.2 meters, it's built to withstand tough environments.
