Septentrio AsteRx-i3 D Pro+

AsteRx-i3 D Pro+ – Advanced GNSS/INS Receiver with Dual-Antenna Sensor Fusion

The AsteRx-i3 D Pro+ is a high-performance GNSS/INS receiver board that delivers centimetre-level accuracy and full 3D orientation through advanced sensor fusion technology. Combining quad-constellation, multi-frequency, all-in-view RTK positioning with an integrated inertial sensor, it provides reliable heading, pitch and roll even in the most demanding environments.

Designed for maximum flexibility, the AsteRx-i3 D Pro+ supports both single- and dual-antenna configurations, enabling precise heading data from initialisation without relying on movement or magnetic sensors. Its dead-reckoning capability ensures continuous positioning when GNSS signals are temporarily unavailable, making it ideal for dynamic systems such as robotics, autonomous vehicles and precision navigation.

Engineered for OEM integration, the AsteRx-i3 D Pro+ features low power consumption, a lightweight, compact design, and full access to raw GNSS and IMU data for advanced custom applications. Powered by Septentrio’s GNSS+ Algorithm Suite, including AIM+ anti-jamming and anti-spoofing technology, LOCK+, IONO+, and APME+, it maintains exceptional performance and integrity even in challenging RF or multipath conditions.

Integration is fast and straightforward through the intuitive Web User Interface (WebUI), offering simple configuration, monitoring and control from any connected device, along with automatic lever-arm optimisation and comprehensive support resources.
