Overview & Specifications

Overview

The Holybro mosaic-G5 is a cutting-edge RTK GPS module that harnesses the power of Septentrio's elite mosaic-G5 GNSS receiver. It comes with an RM3100 magnetometer, two high-performance antennas, and an aluminum CNC enclosure. It offers heading and pitch or heading and roll angles in addition to high-accuracy positioning, ideal for autonomous navigation.

With its dual-antenna input, mosaic-G5 can provide compass-less YAW information to the controller (commonly called GPS Heading or Moving Baseline Yaw). Employing GPS as the yaw source instead of a traditional compass eliminates the inaccuracies caused by magnetic interference from vehicle motors, electrical systems, and environmental sources like metallic structures or power lines, ensuring precise yaw reports to the controller and enhancing overall navigation reliability and performance in challenging environments.

Septentrio's mosaic-G5 GNSS receiver module boasts a suite of proprietary technologies that set it apart from the competition. Septentrio’s AIM+ (Advanced Interference Mitigation) technology safeguards against intentional and unintentional jamming sources, ensuring consistent and reliable performance even in challenging RF environments.

Septentrio’s LOCK+ technology ensures optimal tracking even under rapid antenna displacement in the event of high vibrations or shocks, maintaining high accuracy and stable operation in high-dynamic situations. It is ideal for demanding applications such as UAVs and robotics. Furthermore, Septentrio's advanced RAIM+ (Receiver Autonomous Integrity Monitoring) algorithm delivers unmatched integrity and reliability, providing a safety net for mission-critical applications.
