AsteRx SBi3 Pro+ GNSS Receiver
The AsteRx SBi3 Pro+ is a ruggedized IP68-rated and MIL-STD-810G-tested GNSS/INS receiver that offers reliable IMU-enhanced GNSS positioning down to centimeter level, as well as high-accuracy 3D orientation data. It features optional dual-antenna capabilities that enable heading measurement without the need for platform or vehicle movement.
The unit incorporates Septentrio's unique AIM+ interference protection for critical anti-jamming and anti-spoofing mitigation, and also outputs synchronized raw GNSS and IMU data for sensor fusion applications.
