September 16, 2019 - Septentrio, a global supplier of positioning technology for demanding applications, unveiled AsteRx SBi, a new housed GNSS/INS receiver. Within its waterproof enclosure, a GPS/GNSS is coupled with an industrial-grade inertial sensor to provide positioning and 3D orientation (heading, pitch, roll).
Offering the flexibility of either single or dual antenna, AsteRx SBi is designed for integration into any machine monitoring or control system. Location and 3D orientation data is streamed with constant low latency.
Septentrio centimeter-level positioning is based on true multi-frequency, multi-constellation GNSS (GPS, GLONASS, Galileo, BeiDou, QZSS) technology. AsteRx SBicombines GPS/GNSS and an IMU (Inertial Measurement Unit) to deliver positioning together with 3D attitude. Septentrio’s GNSS – IMU 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 AsteRx SBi a positioning solution for machinery operating in environments challenging for GNSS, such as in container yards, urban canyons or near cliffs.
AsteRx SBi comes with built-in Advanced Interference Mitigation (AIM+) technology. In busy urban environments electromagnetic waves can interfere with GPS and GNSS signals. AIM+ offers protection against such interference. A built-in power spectrum plot allows users to analyze interference, helping locate its source and mitigating it.
