AsteRx RBi3 Pro – Rugged GNSS/INS Positioning Receiver

The AsteRx RBi3 Pro is a high-performance, rugged GNSS/INS receiver designed to deliver reliable, centimetre-level positioning and orientation in the harshest environments. With its durable IP69K-rated housing, it withstands extreme temperatures, corrosion, vibration and shock—making it ideal for demanding industrial, surveying and machine control applications.

Featuring multi-frequency, all-in-view GNSS tracking and advanced GNSS+ algorithms, the AsteRx RBi3 Pro ensures uninterrupted accuracy even in challenging conditions. Technologies such as LOCK+, IONO+, and APME+ maintain robust satellite tracking under vibration, protect against ionospheric interference, and eliminate multipath errors for consistently precise results.

The integrated Inertial Navigation System (INS) provides reliable heading, pitch and roll data, maintaining positional continuity during brief GNSS outages. With the dual-antenna option, the receiver also delivers sub-degree GNSS heading accuracy that is independent of movement or magnetic sensors.

Designed for seamless system integration, the AsteRx RBi3 Pro offers open interfaces, an intuitive Web User Interface (WebUI), and powerful software tools for straightforward configuration, control and automatic lever arm optimisation.
