5,690.00$
The AsteRx-i3 D Pro+ is a lightweight, low-power GNSS/INS receiver designed for sensor fusion applications in single or dual antenna configurations. It delivers centimeter-level IMU-enhanced positioning with accurate heading, pitch, and roll, while providing full access to raw GNSS and IMU data. Equipped with AIM+ anti-jamming and anti-spoofing technology and quad-constellation, multi-frequency RTK tracking, it ensures reliable, high-precision navigation in demanding environments. Fast integration is enabled via the intuitive Web Interface, automatic lever arm optimization, and knowledge base support.
Description
AsteRx-i3 D Pro+ – High-Precision GNSS/INS Receiver for Continuous Positioning
Reliable Centimeter-Level Positioning with 3D Orientation
The AsteRx-i3 D Pro+ delivers centimeter-level GNSS positioning combined with full 3D orientation (heading, pitch, and roll) in demanding environments. Its onboard inertial sensor enables dead-reckoning, maintaining accurate navigation even during short GNSS signal outages.
As a flexible GNSS/INS solution, it provides full access to raw GNSS and INS data, supporting multiple antenna configurations for advanced system integration and sensor fusion applications.
Robust Performance in Challenging Conditions
Equipped with Septentrio’s GNSS+ suite, including AIM+, FUSE+, APME+, LOCK+, IONO+, and RAIM+, the AsteRx-i3 D Pro+ ensures reliable tracking, anti-jamming protection, and multipath mitigation under harsh environmental conditions. Its high resilience to mechanical shocks, vibrations, and ionospheric disturbances makes it ideal for machine control, robotics, and industrial applications.
