AsteRx-i3 D Pro – Ready-to-Use GNSS/INS Single-Board Receiver

The AsteRx-i3 D Pro is a compact, high-precision GNSS/INS single-board receiver delivering centimetre-level positioning with full 3D orientation — heading, pitch and roll — even in the most demanding environments. Combining quad-constellation, multi-frequency, all-in-view GNSS tracking with an integrated inertial sensor, it ensures continuous, accurate positioning and orientation data, even during short GNSS interruptions.

Designed for seamless integration, the AsteRx-i3 D Pro offers reliable RTK performance, dead-reckoning capability, and low-latency outputs, making it ideal for industrial and automation systems that demand high-rate, real-time data. Its lightweight, low-power design makes it perfectly suited for OEM integration in mobile, robotic, and machine control platforms.

Powered by Septentrio’s GNSS+ Algorithm Suite – including AIM+, LOCK+, IONO+, and APME+ – the AsteRx-i3 D Pro provides advanced interference protection, robust tracking, and superior reliability under vibration, multipath or ionospheric conditions. Integration is fast and straightforward through the intuitive Web User Interface (WebUI), which allows real-time configuration, monitoring, and optimisation with clear quality indicators and automatic lever-arm adjustment.
