The Standard Pro Mini RTK Receiver V4E by FJDynamics redefines portable GNSS surveying with its compact, lightweight design and powerful high-precision performance. Weighing just 320g, this pocket-sized device delivers centimeter-level accuracy without the need for traditional surveying poles, making it ideal for professionals who require mobility, speed, and reliability in the field.
 
Built for efficiency, the V4E supports 1408 channels and tracks all major GNSS constellations—including GPS, BDS, GLONASS, Galileo, QZSS, and SBAS—ensuring consistent and accurate positioning anywhere on the globe. Its seamless compatibility with NTRIP correction services and multiple data formats allows for flexible integration into existing workflows.
 
The Pro version enhances usability with a built-in IMU tilt compensation (up to 30°) and an onboard LiDAR rangefinder, enabling precise measurements even without perfect alignment or direct access to target points. Combined with rugged durability (IP67 rating) and long battery life (≥12 hours), the V4E is engineered for demanding environments and all-day operation.
 
Whether used in construction, agriculture, surveying, or utilities, the V4E offers a fast, reliable, and cost-effective solution for high-accuracy positioning—anytime, anywhere.
