Enhanced GNSS/INS Receiver
The AsteRx RBi3 Pro is a high-performance multi-frequency GNSS/INS receiver delivering reliable centimeter-level positioning together with precise orientation. It is engineered to operate in the harshest environments, withstanding extreme temperatures, corrosion, shock, and vibration for dependable field performance.
Sporting AIM+, IONO+, APME+, RAIM+, FUSE+ and LOCK+ tech that safeguards against intentional and unintentional interference. It actively detects and mitigates a wide range of jamming sources, ensuring uninterrupted, high-precision GNSS performance.
Designed for seamless integration, the receiver offers fully documented interfaces, commands, and data messages. Open tools such as WebUI and RxTools simplify configuration, monitoring, and control within any system.
Key Strengths
Precise heading with dual-antenna option: With optional dual-antenna support, the AsteRx RBi3 Pro delivers precise, position-independent heading combined with centimeter-level RTK accuracy. GNSS-based heading performs reliably in both static and dynamic conditions, eliminating dependence on vehicle motion or magnetic sensors.
Continuous positioning with integrated INS: The integrated inertial navigation system (INS) maintains positioning continuity during temporary GNSS outages, such as signal blockages. This ensures stable and reliable output even in challenging conditions where satellite visibility is limited.
Reliable positioning in harsh environments: The ultra-rugged design, combined with advanced multi-frequency tracking and GNSS+ technologies, ensures consistent accuracy in chemically aggressive environments and under high mechanical stress. It is built for applications where reliability cannot be compromised.
