Septentrio mosaic-G5 P3H™
The mosaic-G5 P3H™ from Septentrio is purpose-built to meet the persistent demand for compact, highly accurate GNSS solutions. This multi-frequency receiver module delivers centimeter-level RTK positioning and sub-degree heading in a package just 22.8 × 16.4 mm. Its combination of precision, robustness, and small size is reshaping the possibilities for size and power constrained designs for drones, robots, and other autonomous systems.
In addition to high-accuracy positioning, the mosaic-G5 P3H™ provides heading plus pitch or roll angles to unlock orientation data that’s critical for autonomous navigation. Backed by Septentrio’s GNSS+ technology, the P3H sets a new benchmark for performance in mass-market GNSS modules. Designed for high-volume integration, it offers a fully documented interface library and comes bundled with RxTools software for straightforward configuration, monitoring, and analysis.
