AsteRx SB3 Pro is a multi-frequency GNSS receiver  delivering centimeter-level RTK positioning in a  rugged enclosure. Its compact and rugged housing  is tailored for effortless integration in machine  automation applications.


KEY FEATURES

* All in view, multi-constellation, multi-frequency  satellite tracking 

* Robust and compact IP68 weatherproof housing 

* AIM+ Interference monitoring and mitigation  function 

* Sub-degree GNSS heading option 

* GNSS+ algorithms guaranteeing reliable  performance


Rover applications 

 The AsteRx SB3 Pro is a rover GNSS receiver with best-in-class positioning performance, employing Septentrio’s latest  multifrequency multi-constellation RTK technology. It delivers  robust and reliable positions in challenging environments in  both single or dual antenna modes. Its specialized design  makes it an easy-to-use, cost-efficient rover receiver. 


Feature-rich in a compact design 

Simultaneous multi-constellation, multi-frequency tracking  combined with the GNSS+ toolset and high-update rate, lowlatency output mean that AsteRx SB3 Pro is ideally suited  for any space-constrained industrial application under any  conditions.  


Ease of integration 

The AsteRx SB3 Pro integrates seamlessly into any system  thanks to fully documented interfaces, commands and data  messages. Septentrio’s open interfaces and software tools  (WebUI, RxTools) make it easy to the integrate, configurate  and control the AsteRx SB3 Pro.
