AsteRx-m3 Pro

Ultra-low power GNSS rover receiver

  • All-in-view satellite tracking on 3 frequencies 

  • Best-in-class reliable RTK position accuracy (cm-level) 

  • Best SWaP on the market (Size, Weight and Power)  

  • AIM+  advanced anti-jamming, anti-spoofing technology as part of the GNSS+ Technology Suite  

  • Easy-to-integrate rover receiver 

  • GNSS heading (optional) available directly from initialization, removes reliance on vehicle dynamics or magnetic sensors 

 

The AsteRx-m3 Pro is a compact, high-performance, ultra-low power GNSS receiver ideal for integration into demanding industrial applications where power and space are at a premium. It incorporates the latest multi-frequency multi-constellation GNSS technology as well as advanced anti-jamming algorithms for unmatched availability and reliability. This receiver is specifically designed for rover* applications, making it an ideal easy-to-integrate solution for any kinematic application where reliable high-accuracy positioning is needed. It is available in single or dual antenna mode, for high quality heading & pitch or heading & roll information.  

*A rover receiver, unlike a base station, is a receiver on the move. This type of receiver calculates its position with centimeter-level accuracy by analyzing signals from various GNSS satellites and by using correction information from base station receivers. 

 

AIM+ anti-jamming and RF spectrum monitoring system 

The AsteRx-m3 Pro 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 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. 
 

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 Pro 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.
