AntaRx-Si3 GNSS/INS Smart Antenna

Septentrio AntaRx-Si3 GNSS/INS Smart Antenna

Product Information

Ultra-Rugged and Precise GNSS Receiver Integrated with Inertial Sensor

The AntaRx-Si3 GNSS/INS (Inertial Navigation System) receiver provides centimetre-level positioning alongside orientation (heading, pitch, and roll angles) and dead-reckoning capabilities. This fusion of sensors ensures exceptional performance and reliability, even in the most demanding environments. Encased in a high-impact resistant polycarbonate housing with IP69K sealing, the AntaRx-Si3 GNSS/INS Smart Antenna is built to withstand harsh conditions. Internally, proprietary technology and advanced algorithms sustain robust tracking despite intense vibrations or shocks. The smart antenna is also available in a GNSS-only variant. By incorporating an auxiliary GNSS antenna, users can obtain heading and pitch or heading and roll measurements without movement.

GNSS+ Technologies – Superior Performance in Challenging Conditions

Mechanical vibrations or rough terrain can disrupt satellite tracking. LOCK+ dynamically adjusts receiver parameters to maintain position stability.

Ionospheric activity poses challenges to GNSS signals, leading to RTK fix loss or complete signal loss. Septentrio’s expertise in supporting applications in highly iono-active regions has led to IONO+, the most advanced protection against ionospheric disturbances available on any receiver.

Metallic and large nearby structures can reflect GNSS signals, causing multipath errors. The APME+ system distinguishes direct and reflected signals, enhancing both positioning and measurement accuracy. APME+ is bias-free and can be disabled, in line with Septentrio’s commitment to maximum configurability.

AIM+ Anti-Jamming and RF Spectrum Monitoring System

Septentrio’s AIM+ system provides built-in protection against intentional and unintentional jamming through sophisticated sampling and mitigation mechanisms. It automatically suppresses a wide range of interferers, from simple continuous narrow-band signals to complex wideband and pulsed transmitters, ensuring uninterrupted high-precision GNSS reception.

Easy Integration with Intuitive Web App

The AntaRx-Si3 GNSS/INS Smart Antenna offers fully documented interfaces, commands, and data messages for seamless integration. Included GNSS receiver control and analysis software RxTools enables receiver configuration, monitoring, as well as data logging and analysis.

The receiver features an intuitive web user interface for convenient operation and monitoring, allowing control from any mobile device or computer. The web interface utilises easily interpretable quality indicators, ideal for real-time monitoring during operations.

AntaRx is also available in GNSS only and as an Auxiliary GNSS Antenna compatible with AntaRx receiver.
