Luka

A new generation GNSS RTK system.

Luka GNSS Receiver is a small and lightweight, high performance GNSS Receiver developped and built from scratch by Tersus GNSS.
With advanced features such as calibration-free tilt compensation and a high-performance multi-constellation and multi-frequency GNSS board, Luka offers supreme accuracy and stable signal detection even in demanding environments such as urban canyons and under canopy.

The LUKA GNSS Receiver supports calibration-free tilt compensation function which is immune to magnetic disturbances, leveling pole is not required. With an internal high-performance multi-constellation and multi-frequency GNSS board, the LUKA GNSS Receiver can provide high accuracy and stable signal detection. The high-performance antenna can speed up the time to first fix (TTFF) and improve anti-jamming performance.There are four versions of the LUKA GNSS Receiver, which can provide selectivity for the requirement from different users.

Choose from two versions: Basic and Ultimate, and experience
Tersus ExtremeRTK technology with the lightweight Luka GNSS Receiver.
