Rugged, accurate and versatile

AntaRx-S3 smart antenna is designed to be strong inside and out. High impact resistance polycarbonate housing with IP69K sealing protects the receiver. On the inside, proprietary technology and advanced algorithms ensure robust tracking despite heavy vibrations or shocks. Best-in-class RTK is provided by Septentrio core technology, perfected over the last 20 years to deliver the highest level of positioning accuracy. Choose the best fit for your system with either single or dual antenna modes for heading & pitch or heading and roll angles, 4G cell option or GNSS/INS version. Adding an auxiliary GNSS antenna to your receiver enables heading and pitch or heading and roll measurements without the need for movement.

The GNSS+ Technologies - Top performance in challenging environments

Mechanical vibrations or shocks caused by rough terrain can wreak havoc with satellite tracking. LOCK+ automatically adjusts the parameters of this receiver so you never lose position.

Activity in the ionosphere is a problem for GNSS signals, from loss of RTK fix to total loss of signal lock. Having honed our skills, supporting applications in the most iono-active areas on Earth,  the result is IONO+: the most advanced protection against ionospheric disturbances to GNSS signals on any receiver.

Metal and large nearby structures can reflect GNSS signals and produce multipath. The APME+ system effectively disentangles direct and reflected signals enhancing both position and measurement quality. APME+ is bias free and, in line with Septentrio’s commitment to maximum configurability, can be disabled.

AIM+ anti-jamming and RF spectrum monitoring system

AIM+ offers built-in protection against intentional and unintentional jamming using a sophisticated system of sampling and mitigation mechanisms. Your high-precision GNSS receiver can automatically suppress the widest variety of interferers from simple continuous narrow-band signals to the more complex wide band and pulsed transmitter.  

Easy-to-Integrate with an intuitive web app 

TheAntaRx-S3 smart antenna comes with fully documented interfaces, commands and data messages. The included GNSS receiver control and analysis software RxTools allows receiver configuration, monitoring as well as data logging and analysis. 

The receiver includes an intuitive web user interface for easy operation and monitoring allowing you to control the receiver from any mobile device or computer. The web interface also uses easy-to-read quality indicators ideal to monitor the receiver operation during the job at hand.
