Septentrio AsteRx-m3 Pro+ GNSS Receiver Board

The AsteRx-m3 Pro+ from Septentrio is an ultra-low power versatile GNSS receiver, available in single or dual antenna mode, with the flexibility to be used either as a base station or a rover receiver.



The AsteRx-m3 Pro+ is a best-in-class versatile OEM GPS/GNSS receiver board combining Septentrio’s top core GNSS technologies, a product of over two decades of innovation. It is a triple-frequency multi-constellation GNSS receiver featuring top positioning performance with flexibility to be used either as a base station or a rover receiver. In dual antenna mode, it provides heading & pitch or heading & roll information on top of reliable and accurate positioning. This product also features a top-quality CPU with a 100Hz data update rate.

The AsteRx-m3 Pro+ GNSS receiver features AIM+ Advanced Interference Mitigation and monitoring technology which 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.

The AsteRx-m3 Pro+ provides RTK positioning at the lowest power consumption of any comparable device on the market. Its minimal SWaP (Size, Weight and Power) means longer operation on a single battery charge and better value in the field.

LOCK+ automatically adjusts the parameters of the AsteRx-m3 Pro+ receiver so you never lose position due to mechanical vibrations or shocks can wreak havoc with satellite tracking.

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+ technology effectively disentangles direct and reflected signals enhancing both position and measurement quality.

The AsteRx-m3 Pro+ comes with fully documented interfaces, commands and data messages. The included GNSS receiver control and analysis software RxTools allows receiver configuration, monitoring as well as data logging and analysis.

The 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.
