AsteRx SB3 CLAS

Advanced housed GNSS positioning and heading

AsteRx SB3 CLAS is Septentrio’s most advanced housed multi-frequency GNSS receiver. It uses the latest triple-band GNSS core technology for reliable centimeter-level RTK positioning and sub-degree heading. 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). With flexibility to be used as a rover or a base station AsteRx SB3 CLAS also has an ultra-high update rate and logging functionality. Enclosed in a ruggedized IP68 housing, it delivers top performance even in the harshest environments. 

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.
