Ultra-Compact GNSS Receiver Modules

Power-efficient GNSS modules  for precise positioning in high-volume applications like drones, robotics, and autonomous systems—even in the most challenging environments. 

Septentrio, a Hexagon company, has announced the launch of its latest innovation in GNSS technology—the mosaic-G5 series. These are the smallest GNSS receivers the company has produced to date, measuring just 23 mm x 16 mm and weighing as little as 2.2 grams. Designed to meet the growing demand for high-accuracy positioning in compact, power-constrained systems, these modules are ideal for drones, robots, and industrial applications requiring reliable performance at scale.

The mosaic-G5 receivers bring advanced GNSS capabilities to environments where signal degradation or obstructions are common. Thanks to their low power consumption and ultra-compact design, they offer exceptional performance without compromise, even in the most challenging conditions.“The new mosaic-G5 modules expand our successful mosaic line to better serve high-volume drone and robotic applications,” said François Freulon, Director of Product Management at Septentrio.

The product family includes:

• mosaic-G5 P1: A triple-band module offering robust, entry-level precision ideal for applications like inspection drones and robotic mowers.
• mosaic-G5 P3: A quad-band receiver that ensures strong reliability in tougher environments—suited for delivery and light show drones.
• mosaic-G5 P3H: A triple-band module with heading capabilities, optimized for devices requiring accurate directional data in tight spaces, such as compact autonomous machines.

These new modules complement Septentrio’s existing mosaic-X5, which remains the gold standard for GNSS resilience, offering anti-jamming and anti-spoofing in a compact form. Like the X5, the G5 series is fully compatible with open-source autopilot systems like PX4 and ArduPilot, significantly easing development efforts.

To support integration and evaluation, Septentrio offers the mosaic-go G5 evaluation kit, along with RxTools, a free user interface for setup and testing.Samples of the mosaic-G5 modules are available now, with full-scale shipments planned later this year.
