The AsteRx SB3 Sx is a compact, high performance  housed GNSS receiver ideal for integration into  demanding industrial applications where power  and space are at a premium. It delivers out-of-the  box sub-decimeter accuracy thanks to the built-in  PPP-RTK (a.k.a. SSR) correction service that will be  active for a five-year period.


KEY FEATURES

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

* Sub-degree GNSS heading & pitch or heading & roll 

* AIM+ Interference monitoring and mitigation  function 

* Sub-decimeter accuracy out of the box, with no additional service subscription required 

* Five-year PPP-RTK corrections included  

* Compact, yet rugged design


Plug-and-play sub-decimeter accuracy 

 The AsteRx SB3 Sx offers plug-and-play sub-decimeter  accuracy enabled by the built-in PPP-RTK corrections. No  need for selecting, setting-up and maintaining any additional subscription services. PPP-RTK is the latest generation of  GNSS correction services, which uniquely combines near-RTK accuracy with quick convergence time.  


Feature-rich in a compact design 

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


Ease of integration 

The AsteRx SB3 Sx 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 Sx.
