mosaic-G5 P3

Ideal for Size-Constrained Applications

The Septentrio mosaic-G5 P3 is a next-generation, ultra-compact multi-frequency GNSS receiver module designed for applications where space and power are limited. Delivering high-accuracy positioning with low latency, it is an excellent choice for UAVs, robotics, autonomous systems, and portable devices that demand reliable navigation in challenging environments.

Powered by GNSS+ technology, the mosaic-G5 P3 ensures exceptional resilience against interference and multipath, setting a new performance standard in mass-market GNSS solutions. Easy to integrate and compatible with open-source autopilots, this receiver is engineered for seamless deployment in modern autonomous technologies.

Ultra-Compact, Lightweight Design

At just 22.8 x 16.4 mm and 2.2 g, the mosaic-G5 P3™ offers an impressive size-to-performance ratio, making it ideal for space-limited applications without compromising on accuracy.

Ultra-Low Power with RTK Precision

Engineered for efficiency, this module delivers real-time kinematic (RTK) positioning with minimal power consumption. It supports full raw GNSS data output and is future-ready with compatibility for Galileo HAS services, enabled through software updates.

Multi-Frequency & Multi-Constellation

The mosaic-G5 P3™ maximizes availability and reliability by tracking all-in-view constellations across multiple frequency bands. It leverages signals from GPS/QZSS, BeiDou, Galileo, and GLONASS, with planned support for QZSS L6 CLAS via future updates, ensuring robust performance even in obstructed-sky conditions.
