AsteRx-i3 S Pro+ delivers reliable centimeter  level positioning combined with 3D orientation  in demanding environments. Its sensor fusion  provides orientation and positional dead-reckoning, making it ideal for systems that  require continuous positioning even during  short GNSS outages. AsteRx-i3 S Pro+ allows  full flexibility of usage providing raw data and  enabling tethered IMU installation precisely at  the motion point-of-interest.

KEY FEATURES

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

*Full access to raw GNSS and IMU data

*Tethered IMU

*Heading available immediately from initialization with dual antenna configuration

*Lightweight, low power and compact

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

*Fast and easy integration with the intuitive Web UI and automatic lever arm optimization

Reliable and robust  

The AsteRx-i3 S 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  multi-constellation, multi-frequency, accurate and reliable RTK  is enhanced by a powerful GNSS/INS integration accurately  measuring heading, pitch and roll. While a single antenna  allows a lean configuration, the dual antenna enables  heading measurement without the need for movement.  AsteRx-i3 S Pro+ 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. 

Ideal for any integration 

The AsteRx-i3 S Pro+ is not only delivering an already  integrated position, but it also provides raw GNSS and IMU  data, already synchronized and in a single data stream for  customers that will integrate those components with other  sensors for a larger data fusion system (i.e. lidar). Having  GNSS and IMU hardware already integrated and data  streams already synchronized enables users to focus on their  own core technology without having to integrate GNSS and  IMU sensors themselves. The tethered IMU allows to install  the board where there is more space for it and to install the  IMU close to the point of interest with the orientation aligned  to the frame of interest.  

Easy to integrate 

The AsteRx-i3 S Pro+ delivers a full INS system on a single  board for the maximum ease of hardware integration.  Septentrio’s web interface and software tools make it easy to  integrate, configure and control the AsteRx-i3 S Pro+ receiver.
