Rugged GNSS/INS system for machine monitoring and control

November 7th, 2019, Published in Articles: PositionIT

Septentrio expanded its GNSS/INS portfolio with the AsteRx SBi, a ruggedised receiver which fuses high-accuracy GPS/GNSS with a high-performance inertial sensor to provide reliable positioning and 3D orientation, ideal for machine control and logistic applications. Within its rugged, waterproof enclosure a high-performance GPS/GNSS is coupled with an industrial-grade inertial sensor to provide high-accuracy, reliable positioning and 3D orientation (heading, pitch, roll). Offering the flexibility of either single or dual antenna, the solution is designed for quick and easy integration into any machine monitoring or control system. Reliable location and 3D orientation data is streamed with a high update rate and constant low latency.  The company’s centimetre-level positioning is based on true multi-frequency, multi-constellation GNSS (GPS, Glonass, Galileo, BeiDou, QZSS) technology. AsteRx SBi combines GPS/GNSS and an industry-grade inertial measurement unit (IMU) to deliver precise positioning together with 3D attitude. The integration algorithm enables continuous positioning in environments of low satellite visibility where short GNSS outages are possible. This is referred to as coasting or dead reckoning and can happen near high structures, under bridges or under thick foliage. This makes the system a robust positioning solution for machinery operating in environments challenging for GNSS, such as in container yards, urban canyons or near cliffs. The solution also has Advanced Interference Mitigation (AIM+) technology built-in.
