AsteRx SBi3 Pro GNSS/INS multi-frequency  receiver delivers reliable centimeter level  positioning together with 3D orientation in  challenging environments. Thanks to the built-in  inertial sensor, it provides orientation (heading,  pitch and roll) as well as dead reckoning making  it ideal for systems that require positioning  under any condition. This housed highperformance GNSS/INS system is ideal for rapid  integration into machine control or ground  robotic applications.


KEY FEATURES

*Centimeter-level GNSS positioning enhanced by an IMU and optionally vehicle velocity

*Heading with a single or dual GNSS antenna

*Pitch and roll

*Robust and compact IP68 weatherproof housing

*AIM+ Advanced Interference Mitigation technology, as part of the GNSS+ algorithm suite

*Fast and easy integration with the intuitive Web Interface, automatic lever arm optimization and support Knowledge Base

 

Reliable and robust  

The AsteRx SBi3 Pro is a state-of-the-art GNSS/INS rover  receiver designed to provide robust and reliable position  and 3D attitude in the most challenging of conditions.  Septentrio’s renowned multi-constellation, multi-frequency  RTK is further enhanced by a powerful GNSS/INS integration  that allows to have accurate heading, pitch and roll using a  single antenna for the most efficient and lean integration. It  features Advanced Interference Mitigation (AIM+ ) technology  which can suppress the widest variety of interferers, from  simple continuous narrowband signals to the most complex  wideband and pulsed jammers. 


Ease of use

The integrated positioning + orientation solution of AsteRx  SBi3 Pro streams out into several wired connectors. With  clear marking of the inertial reference point together with a  sturdy mounting connector it is an ideal system for those who  are looking for an intuitive GNSS/INS, ready for production.


Easy-to-integrate 

The AsteRx SBi3 Pro provides a full GNSS/INS system in a  single easy to mount, low weight and low power box. With a  quick an easy fit into any type of application it ensures reduced  integration time and fast time to market. Septentrio’s intuitive  software tools (WebUI, RxTools) make it easy to integrate,  configure and control the AsteRx SBi3 Pro. All of its interfaces,  commands and data messages are fully documented.
