Description

AntaRx-Si3 – Rugged GNSS + INS Receiver for Precision Navigation

High-Performance GNSS/INS for the Toughest Environments

The AntaRx-Si3 is a next-generation GNSS/INS (Inertial Navigation System) receiver delivering centimeter-level positioning accuracy combined with precise orientation—including heading, pitch, and roll angles—and reliable dead-reckoning performance.
By integrating advanced inertial sensors with a high-precision GNSS engine, the AntaRx-Si3 ensures uninterrupted navigation and orientation even in the most challenging conditions, where satellite visibility is limited or intermittent.

Engineered for durability, the AntaRx-Si3 smart antenna features a rugged polycarbonate housing with IP69K-rated sealing, ensuring complete protection against water, dust, and physical impact. Internally, it incorporates proprietary algorithms and advanced signal processing to maintain stable performance under strong vibrations or shocks.
A GNSS-only variant is also available, and by connecting an auxiliary GNSS antenna, users can obtain heading and pitch or heading and roll measurements without movement.

GNSS+ Technologies – Assured Accuracy in Every Environment

LOCK+ Technology
Vibrations or shocks from harsh terrain can disrupt GNSS tracking. LOCK+ dynamically adjusts receiver parameters in real time, ensuring your positioning remains stable and continuous no matter the conditions.

IONO+ Protection
Ionospheric activity can degrade GNSS accuracy or cause loss of RTK fix. With IONO+, the AntaRx-Si3 offers industry-leading resilience against ionospheric disturbances—developed from years of experience in high-iono regions worldwide.

APME+ Multipath Mitigation
Nearby metal objects or structures can reflect signals and create multipath errors. APME+ intelligently distinguishes between direct and reflected signals, improving position integrity and measurement precision. It’s completely bias-free and user-configurable, aligning with our commitment to flexibility and control.

AIM+ – Advanced Anti-Jamming & RF Spectrum Protection

The AIM+ system provides built-in RF interference detection and suppression, defending your GNSS receiver from both intentional jamming and unintentional interference.
By leveraging a sophisticated combination of real-time signal sampling and adaptive filtering, AIM+ automatically mitigates everything from continuous narrow-band jammers to complex wide-band and pulsed sources, ensuring uninterrupted high-precision performance.

Easy Integration & Intuitive Control

The AntaRx-Si3 is designed for effortless integration with existing systems. It includes comprehensive documentation, open communication interfaces, and flexible command structures.
Our powerful RxTools software suite supports full receiver configuration, monitoring, data logging, and analysis, simplifying every step from setup to deployment.

A built-in web user interface (Web UI) provides real-time monitoring and control directly from any desktop or mobile device. The dashboard offers clear quality indicators, ideal for field operations and on-site performance checks.
