AsteRx-i S joins Septentrio’s GNSS/INS product portfolio

The AsteRx-i S combines Septentrio’s compact, multi-frequency multi-constellation GNSS engine with ultralight external industrial grade MEMS based IMU.

Calibrated for wide temperature ranges, the AsteRx-i S delivers accurate and reliable GNSS/IMU integrated positioning to the cm-level as well as full attitude at high update rates and low latency.

 

Key benefits for users:

  • GNSS/INS positioning with 3D attitude: heading pitch and roll
  • Multi-constellation, multifrequency, all-in-view RTK receiver
  • AIM+ interference monitoring and mitigation system
  • High-update rate, low-latency positioning and attitude
  • Small & ultralight IMU (10 grams)
  • Robust calibration for wide temperature ranges
  The AsteRx-i S is designed around demanding requirements for size, weight, power consumption and temperature variation. It is ideal for various applications such as inspection with UAV's, UAS photogrammetry, automation, robotics, and logistics. “We are delighted to broaden our AsteRx-i GNSS/INS solutions range, bringing maximum flexibility and choice to our customers. Whether for direct georeferencing in mapping applications with UAVs, for managing containers in a port or for innovative small robots in agriculture, the compactness, affordability and robustness of the AsteRx-i range allows our customers to focus on their success.” said Francesca Clemente, Product Manager at Septentrio.

MicroPilot Integrates xNAV GNSS/INS into Autopilots for Greater Accuracy

MicroPilot recently announced the completion of work to integrate an OxTS xNAV miniature GNSS/INS system in to their UAV autopilots. The interface allows MicroPilot systems to use the blended GNSS/IMU output of the INS in their flight control system. This integration provides accurate positioning. “We were excited to work together with MicroPilot to develop an interface between our systems," said Iain Clarke, Product Manager from OxTS. "As the UAV market continues to grow people are still discovering ways to take advantage of the platform. We hope this development brings new opportunities to customers looking for integrated systems and UAV navigation options.”  

Designed for commercial UAV mapping

The xNAV is a miniature GNSS/INS system. It is designed for commercial UAV mapping applications that require precise geo-referencing capabilities. For UAV based LiDAR, hyperspectral or thermal mapping, a survey-grade INS is crucial. It provides the accurate trajectory information needed to create 3D pointclouds, digital terrain models, and other maps. INS also enhances photogrammetry applications. In addition, it reduces the need for ground control points, lowers image processing time and removes jumps and gaps in data, saving time from reprocessing to fix errors. While many autopilot systems have integrated GNSS, they are usually lower-grade, single frequency receivers only capable of 1-2 m accuracy. By developing an interface with OxTS systems, MicroPilot autopilots can use the centimeter-level RTK position output of the INS in their flight control system. The autopilot also receives the benefit of INS navigation which is robust and protected against GNSS dropouts. Thanks to the integrated GNSS and IMU in the xNAV, as well as OxTS’ tight-coupling technology, the navigation solution is smooth, resistant to GNSS jumps, and position drift is limited even when fewer than 4 satellites are in view. This can allow UASs to fly and navigate confidently in harsher GNSS environments such as urban canyons, near vegetation, or under bridges. “MicroPilot is pleased to work with OxTS,” said Howard Loewen, President of MicroPilot. “This integration will create a better performing system for our customers.”   Shop MicroPilot's line of autopilots at Unmanned Systems Source.
