AsteRx SB Sx

  • Always-on high accuracy, right out of the box
  • Uniquely easy-to-use without the need for additional service subscriptions during a five-year period
  • Short convergence time
  • Sub-decimeter PPP-RTK service is available throughout US and Europe (see coverage maps for details). PPP-RTK is the latest generation of GNSS correction services, which uniquely combines near-RTK accuracy with quick initialization times.
  • Advanced anti-jamming, anti-spoofing with AIM+ technology and advanced GNSS+ algorithms
  • Ruggedized IP68 housing




AIM+ anti-jamming and RF spectrum monitoring system



The AsteRx SB Sx features AIM+ Advanced Interference Monitoring and Mitigation, offers built-in protection against intentional and unintentional jamming and spoofing using a sophisticated system of sampling and mitigation mechanisms. In robotic devices neighboring electronics can produce RF radiation which interferes with GNSS signals. AIM+ offers protection against such interference resulting in faster set-up time and robust continuous operation.

GNSS+ Technologies – top performance in challenging environments

Mechanical vibrations or shocks 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.

Intuitive web user interface

This 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.




Application use

Wherever reliable high-precision GNSS positioning is needed:



Housed GNSS receiver with integrated sub-decimeter corrections 

This housed GNSS receiver offers a unique approach to GNSS positioning. It provides convenient always-on high-accuracy positioning right out of the box. No need for any additional correction service selection, subscription and maintenance. This is made possible by an integration of a PPP-RTK sub-decimeter correction service into Septentrio’s latest core GNSS technology. In a robust IP68 housing AsteRx SB Sx offers a perfect combination of ruggedness and ease-of-use.
