mosaic-G5 P3H UltraLight Dual Smart Antenna for heading and RTK positioning

mosaic-G5 P3H ultraLight Dual Smart Antenna is a next-generation, ultra-lightweight RTK GNSS solution built around the powerful mosaic-G5 P3H module, integrated with a high-precision RM3100 compass and a compact helical antenna. It is purpose-designed for weight-sensitive UAVs, robotics, and mobile applications where every gram matters.

With its advanced multi-band RF front-end, the mosaic-G5 P3H ultraLight Dual Smart Antenna is capable of simultaneously tracking all major GNSS constellations — ensuring robust positioning and centimeter-level accuracy when combined with correction data.

Engineered for flexibility, it supports concurrent reception of GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS, delivering a high-performance navigation solution even in challenging environments. Thanks to its exceptional sensitivity, fast acquisition times, and Septentrio’s AIM+ advanced anti-jamming and anti-spoofing technology, the mosaic-G5 P3H provides reliable, high-precision positioning where traditional receivers struggle.

With its dual-antenna input, the mosaic-G5 P3H can deliver compass-free yaw information to the controller (commonly referred to as GPS Heading or Moving Baseline Yaw). By using GPS as the yaw reference instead of a traditional compass, it eliminates errors caused by magnetic interference from vehicle motors, electrical systems, or external sources such as metallic structures and power lines. This ensures accurate yaw data for the controller and improves navigation reliability and performance, even in challenging environments.

Lightweight, powerful, and dependable — the mosaic-G5 P3H ultraLight GNSS Smart Antenna is the ideal choice for next-generation UAVs, autonomous systems, and precision applications that demand uncompromised performance in a compact form factor.
