Miniature GNSS-INS for UAV Payloads

The RTK-capable Quanta Micro weighs just 38g and features less than 0.02° roll/pitch error and less than 0.06° heading error By Mike Ball / 06 Oct 2022

SBG Systems Quanta Micro GNSS-INSSBG Systems has launched the Quanta Micro, a new dual-frequency/quad-constellation GNSS receiver with embedded IMU providing centimetre-level positioning in a compact form factor. The RTK-capable miniature inertial sensor features less than 0.02° roll/pitch error and less than 0.06° heading error, weighing just 38g with a size of 50 x 37 x 23 mm. Quanta Micro has already been selected for the development of UAV (unmanned aerial vehicle) LiDAR payloads and is ideal for a range of low-SWaP applications.

Quanta Micro includes all the functionality of SBG’s other advanced inertial sensors, including a built-in datalogger, Ethernet connectivity, a PTP server, multiple serial ports, and a CAN port. The easy-to-configure sensor provides a user-friendly built-in web configuration interface, and can also be configured using SBG Systems’ API or ROS drivers.

While the Quanta Micro supports dual GNSS antenna mode to improve heading accuracy in low dynamic applications, it has been designed to maintain exceptional heading performance even in single-antenna mode, making it ideal for UAV payloads that cannot embed two GNSS antennas.

To further enhance real-time performance, the data acquired from the Quanta Micro can easily be post-processed using Qinertia, SBG’s own PPK (Post-Processing Kinematic) tool. This software provides tight coupling of the GNSS and inertial data, and a merge of forward and backward solutions provides the ability to maintain centimetre-level precision even during multiple seconds of GNSS outages and also improves heading errors to less than 0.035° and roll/pitch to less than 0.015°.

Qinertia options include a desktop version with a user-friendly Graphical User Interface (GUI), as well as easy integration into any processing pipelines via a command line interface (CLI), and private or public cloud solutions for workflows running on a server.
