  • Rugged and durable IP69K GNSS receiver
  • High-accuracy RTK positioning with all-in-view, GNSS multi-frequency satellite tracking
  • Sub-degree GNSS heading & pitch or heading & roll
  • Flexibility to be used either as rover or as base station
  • Update rate up to 100 Hz
  • GNSS+ Algorithm Suite   ensure reliable performance in difficult environments  including LOCK+ technology allowing robust satellite tracking under heavy vibrations and shocks
  • Fast and easy integration with the intuitive Web User Interface and support Knowledge Base
  • Japan Centimeter Level Augmentation Service (CLAS) integrated

AsteRx RB3 CLAS high-accuracy GNSS heading receiver is designed to withstand the harshest of working environments in terms of temperature, corrosion as well as shock and vibration.  It offers flexibility of use with no performance compromises. 

It offers the convenience of plug-and-play sub-decimeter accuracy, thanks to the integrated PPP-RTK correction service from Centimeter Level Augmentation Service (CLAS) of Japan’s Quasi-Zenith Satellite System (QZSS).

Reliable positioning in harsh environments 

Ultra-rugged housing combined with multi-frequency tracking and GNSS+ algorithms make AntaRx RB3 CLAS the ideal GNSS receiver for applications that require accurate position in chemically aggressive environments, harsh temperatures, and high mechanical stress. Its high-update rate and low-latency output means quick feedback loops during rotation or movement.  

Reliable heading performance  

With dual-antenna input, AsteRx RB3 CLAS provides precise, reliable and position independent heading combined with centimeter-level RTK. GNSS heading provides unmatched performance in both static and dynamic conditions removing the reliance on vehicle dynamics or magnetic sensors. 

Ease of integration 

The AsteRx RB3 CLAS integrates seamlessly into any system thanks to fully documented interfaces, commands and data messages. Septentrio’s open interfaces and software tools (WebUI, RxTools) make it easy to the integrate, configure and control the AsteRx RB3 CLAS receiver.  

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. 

Advanced Receiver Autonomous Integrity Monitoring (RAIM+)  comprises fault detection mechanisms of the receiver at all the levels including the generation of measurements, quality control and navigation algorithms. Detected faulty measurements, which are typically caused by high multipath or active ionosphere, are removed from the solution. 

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 transmitters as well as lnmarsat and Iridium satellite transmissions.
