FJD N20 Fixed High Power GNSS Station

Locate with precision, anywhere, anytime. The FJD N20 is a fixed, high-power GNSS reference station built for weak or non-existent network areas. A multi-satellite, multi-frequency receiver on a Linux platform pairs with a high-power radio to broadcast centimetre-level RTK corrections over a radius of up to 30 km, no mobile coverage required.

Wide signal coverage

The high-power radio covers up to 30 km in ideal conditions, with switchable high, medium, and low power modes to match the job. Multiple radio protocols and baud rates make it a stable correction source for FJD autosteering systems and other RTK equipment.

Centimetre-level accuracy

Tracking BDS, GPS, GLONASS, Galileo, and QZSS across a wide frequency range, the N20 holds reliable centimetre-level accuracy even in challenging environments.

User-friendly operation

Three independent modules (receiver, radio, antenna) install and connect quickly, and a wireless hotspot serves a web interface for configuration, work modes, and historical coordinates.

Interference detection

Built-in frequency interference detection identifies noisy frequency points and steers around them automatically, improving signal quality without operator input.
