The Septentrio AsteRx-i3 S Pro+ GNSS/INS board delivers continuous, high-precision navigation for autonomous vehicles using IMU integration and Septentrio’s GNSS+ technologies, including AIM+ anti-interference, APME+ multipath suppression, LOCK+ stable tracking, and FUSE+ sensor fusion—ensuring reliable positioning in tunnels, urban canyons, and other GNSS-challenged environments.
High-precision GNSS/INS integration is essential for modern UUVs operating in deep-sea environments where GNSS signals are unavailable. The AsteRx-i3 D Pro+ delivers continuous, centimeter-level navigation accuracy, robust attitude control, and long-duration underwater dead reckoning, ensuring reliable autonomous operations across demanding scientific, industrial, and security missions.
Modern marine navigation requires continuous, centimeter-level positioning and stable attitude data, even when GNSS signals are temporarily lost due to interference, coastal obstacles, or harsh weather. Traditional GNSS alone cannot meet these demands, making integrated GNSS/INS systems essential for precision berthing, offshore engineering, and autonomous navigation.
