AsteRx SB3 Pro+

Advanced housed GNSS positioning and heading receiver

  • Flexibility to be used either as a rover or a base station
  • High update rate and low latency ideal for fast moving vehicles or machine parts
  • All-in-view triple-band satellite tracking for reliable RTK positioning accuracy(cm-level)
  • Robust and compact IP68 weatherproof housing, ready for deployment
  • Triple-band GNSS heading available directly from initialization, removes reliance on vehicle dynamics or magnetic sensors
  • Advanced anti-jamming as part of GNSS+ Algorithms

AsteRx SB3 Pro+ 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. With flexibility to be used as a rover or a base station AsteRx SB3 Pro+ 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 - converting bad environments into good positioning

Mechanical vibrations or shocks caused by rough terrain can wreak havoc with satellite tracking. LOCK+ automatically adjusts the parameters of the AsteRx SB Pro+ GPS / GNSS 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 Advanced Multipath Mitigation Technology APME+ 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. 

    Intuitive web user interface

    The AsteRx SB Pro+ 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.

    Ease of operation

    Wired, robust connectivity is available on the back panel. The AsteRx SB3 Pro+ GNSS receiver includes USB, Serial and Ethernet  communication with the aid of robust professional ODU connectors.
