Septentrio, a global supplier of positioning technology for “demanding applications,” has announced a new addition to its GNSS/INS portfolio.
AsteRx-i S UAS combines GNSS technology with an industrial-grade inertial sensor to provide high-accuracy, reliable positioning and 3D orientation (heading, roll and pitch) to unmanned aicraft systems (UAS) and other compact robotic systems. Septentrio’s introduction of the AsteRx-i S UAS adds to the company’s existing UAS products, AsteRx m2 and m2a UAS.
The optimized SWaP (size, weight and power) increases a drone’s battery life, resulting in longer flight times and improved productivity. The receiver, the size of a credit card, is designed for easy integration into any UAS and is compatible with autopilots such as Pixhawk and ArduPilot. It is a single-package GNSS/INS product, with an on-board inertial measurement unit and standard connectors, allowing flexibility of sensor choice.
“Quick receiver integration makes the lives of our customers easier. It also speeds up their system’s time-to-market,” says Danilo Sabbatini, product manager at Septentrio. “Our goal was to combine a high-performance product with a simple and flexible plug-and-play integration design, suitable for any aerial system.”
Septentrio says its centimeter-level positioning is based on multi-frequency, multi-constellation GNSS technology (GPS, GLONASS, Galileo, BeiDou, QZSS). Septentrio’s GNSS – IMU integration algorithm provides continuous positioning during short GNSS outages (coasting), which can happen in flight near high structures, under bridges or during banking turns, for example.
The AsteRx-i S UAS comes with built-in advanced interference mitigation (AIM+) technology. For drones, where many electronics are put into a small space, neighboring devices can emit electromagnetic radiation, interfering with GPS and GNSS signals, explains Septentrio. AIM+ offers protection against such interference, resulting in faster setup times and continuous operation. Further, a built-in power spectrum plot allows users to analyze interference, helping to locate its source and mitigate it.
