Overview of holybro hrtk mosaic-h

The Holybro hrtk Mosaic-H is an advanced RTK GPS module that leverages the capabilities of Septentrio’s top-tier mosaic-H GNSS receiver. It includes an IST8310 magnetometer, dual high-performance antennas, and a robust aluminum CNC housing. This module is equipped with a variety of versatile features, including easy configuration, spectrum analysis, data logging, and post-processing, making it suitable for numerous applications.

With its dual-antenna input, mosaic-H can provide compass-less YAW information to the autopilot (commonly called GPS Heading or Moving Baseline Yaw). By employing GPS as the yaw source instead of a traditional compass, it 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 autopilot and enhancing overall navigation reliability and performance in challenging environments.

Septentrio’s mosaic-H GNSS receiver module features a range of proprietary technologies that distinguish it from its competitors. Septentrio’s AIM+ (Advanced Interference Mitigation) technology protects against both intentional and unintentional jamming sources, guaranteeing consistent and reliable performance even in demanding RF environments.

Septentrio’s LOCK+ technology ensures optimal tracking even during rapid antenna displacement caused by high vibrations or shocks, maintaining high accuracy and stable operation in dynamic situations. This makes it perfect for demanding applications such as UAVs and robotics. Additionally, Septentrio’s advanced RAIM+ (Receiver Autonomous Integrity Monitoring) algorithm offers exceptional integrity and reliability, providing a safety net for mission-critical applications.
