AsteRx SB

The AsteRx SB is a unique blend of technologies combining the best RTK performance and flexibility in a compact and ruggedized IP68 housing. Multi-constellation, triple-frequency GNSS technology ensures highly accurate and reliable positioning. The compact and low-power design includes a wide selection of connection options for integration flexibility into your system. The AsteRx SB is the ideal high-performance GNSS receiver for demanding applications where size, weight and power are at a premium.

The GNSS+ toolkit - converting bad environments into good positioning

Mechanical vibrations or shocks caused by rough terrain can wreak havoc with satellite tracking. LOCK+ automatically adjusts the tracking loop parameters of the AsteRx SB 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 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 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. The AsteRx SB can 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


AsteRx SB web interface

The AsteRx SB 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.
