AsteRx-m3 Fg is Septentrio’s best-in-class OEM board. It is a multi-frequency multi-constellation GNSS receiver featuring top positioning performance with flexibility to be used either as a base station or as a rover. In dual antenna mode it provides heading & pitch or heading & roll information on top of reliable and accurate positioning. This receiver is specifically designed for marine survey and construction with RTK as well as Marinestar PPP high-accuracy positioning.

AIM+ anti-jamming and RF spectrum monitoring system 

The AsteRx-m3 Fg GNSS receiver features  AIM+ Advanced Interference Mitigation and Monitoring Technology, 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. 

Optimized SWaP 

AsteRx-m3 Fg  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. 
 

Top performance in challenging environments with GNSS+ 

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

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.  
 

Easy-to-Integrate with an intuitive web app 

AsteRx-m3 Fg GPS/GNSS receiver 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.
