Heerbrugg, Switzerland – Leica Geosystems announced its latest innovation in 3D GNSS choke ring antenna. The new Leica AR20 brings new levels of performance for reference station and monitoring applications. Outstanding tracking performance, excellent phase center symmetry and multipath suppression across all GNSS frequency bands are the hallmarks of this 3D GNSS antenna.

The Leica AR20 is designed for permanent and semi-permanent reference network installations, and meets all requirements for a reliable and long lasting antenna. It is future proof for all satellite signals.

The AR20 provides superior tracking performance by using variable choke rings. The precision design also allows for very low and stable phase center offsets, and very smooth symmetry of the phase center variations versus azimuth and elevation.

With an excellent axial ratio at low elevations, the AR20 provides results with multipath rejection across all GNSS frequency bands including L5, due to the 3D inside design.

The newly-designed AR20 choke rings are treated with a new and robust double treatment for longer lasting durability in all environments. An optional radome cover is also available for added protection.
