With the CRPA-Guard, Lange-Electronic introduces a GNSS front-end device that combines antenna functionality and adaptive signal processing in a single system. The integrated Controlled Reception Pattern Antenna (CRPA) with four antenna elements enables targeted suppression of interference signals (nulling) as well as the evaluation of incoming GNSS signals before they reach the downstream receiver.

By combining spatial signal processing with an integrated GNSS receiver featuring RTK capability, the system achieves centimeter-level positioning—even in the presence of interference such as jamming and spoofing. At the same time, interference sources can be detected, classified, and reported to higher-level systems.

CRPA-Guard is currently designed for stationary applications and can replace a conventional GNSS antenna with minimal integration effort. Typical use cases include critical infrastructure, surveying, and safety-critical navigation.
