Septentrio has expanded its mosaic-G5 GNSS receiver ecosystem to streamline integration for robotics and UAV applications. The move includes new commercial partnerships and the release of open-source designs.
Why it matters
The expansion aims to simplify the integration of high-precision positioning technology into complex robotics and UAV systems. By providing accessible reference designs, developers can more efficiently incorporate GNSS capabilities into their hardware.
The mosaic-G5 GNSS modules maintain a compact footprint of 23 mm by 16 mm. Each unit weighs exactly 2.2 grams to minimize impact on system payload.
The players
Septentrio
Septentrio is a designer and manufacturer of high-precision GNSS positioning technology for demanding industrial applications.
Hexagon
Hexagon is a global leader in sensor, software, and autonomous solutions that is the parent company of Septentrio.
Hoverfly
Hoverfly is a developer of drone-in-a-box solutions and persistent aerial security technology.
CUAV
CUAV specializes in the development of autopilots and hardware components for unmanned aerial vehicles.
The details
Septentrio, a subsidiary of Hexagon, released open-source hardware reference designs including the mosaicG5-HAT, TeenG5, moTi, and G5Dot on GitHub. The company also announced that Hoverfly and CUAV have joined as new commercial partners to support the broader ecosystem.
Timeline
The news regarding the ecosystem expansion was published on October 5, 2026.
The Tech Race
This move reflects a broader trend of hardware manufacturers utilizing open-source reference designs to capture developer mindshare. By commoditizing the integration process, Septentrio positions itself against competitors that maintain more restrictive proprietary hardware ecosystems.
Engineers and developers can now utilize official reference designs to accelerate product development cycles for UAV and robotics hardware. This availability reduces the time and engineering overhead typically required for complex sensor integration.
The takeaway
The move underscores the growing importance of accessible hardware ecosystems in the rapid prototyping of robotics. Developers should leverage these open-source designs to optimize their own GNSS implementation projects.
