The Septentrio AsteRx-i3 D Pro+ GNSS/INS Receiver Module is a high-performance, state-of-the-art positioning and orientation solution designed for demanding industrial, robotics, autonomous vehicle, logistics, and machine control applications. This advanced GNSS/INS module delivers centimeter-level positioning accuracy combined with precise 3D attitude (heading, pitch, and roll) even in challenging environments such as urban canyons, high-interference zones, or during short GNSS signal outages.

The AsteRx-i3 D Pro+ integrates multi-constellation and multi-frequency GNSS support, tracking GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS signals simultaneously through 544 hardware channels. It supports all major correction formats including RTK, DGPS, SBAS, RTCM, and NTRIP, enabling fast initialization and highly reliable real-time positioning.

A key strength of this module is its tight GNSS and IMU integration, delivering accurate dead-reckoning and continuous positioning when GNSS signals are temporarily unavailable. The onboard inertial sensor provides high-rate IMU data, allowing seamless fusion with other sensors such as LiDAR, odometry, or cameras for advanced navigation and sensor-fusion systems.

The module supports both single-antenna and dual-antenna configurations. Single-antenna mode enables a compact system design with accurate heading, while the dual-antenna setup provides instantaneous heading without motion, ideal for autonomous platforms and precision guidance systems.

To ensure signal integrity and security, the AsteRx-i3 D Pro+ features Septentrio’s patented AIM+ technology, offering industry-leading anti-jamming and anti-spoofing monitoring and mitigation. This makes it highly suitable for safety-critical and mission-critical applications.

Designed for easy integration, the module comes in a compact, lightweight, and low-power form factor, with multiple high-speed interfaces including USB, Ethernet, serial ports, and event markers. Full access to raw GNSS and IMU data is provided, enabling system developers to customize processing and integration as per application requirements.

With wide operating temperature range, vibration resistance (MIL-STD-810G), and global certifications, the AsteRx-i3 D Pro+ is a reliable solution for professional and industrial deployments requiring precision, robustness, and long-term performance
