mosaic-H GNSS modules

High-Precision Dual-Antenna RTK Solutions with Septentrio mosaic-H

When standard single-antenna GPS positioning falls short in static or slow-moving scenarios, the Septentrio mosaic-H heading module delivers uninterrupted, high-accuracy attitude data. By leveraging Moving Baseline RTK technology between two distinct multi-band antennas, this ultra-compact module calculates absolute yaw, heading, pitch, or roll instantly upon startup. This eliminates the need for inertial warm-up runs or vulnerable magnetic compasses.

At GNSS Store, we provide versatile mosaic-H evaluation kits, plug-and-play USB dongles, and custom integration boards featuring standard SMA connectors, SD card logging, and intuitive web interfaces for seamless developer onboarding.

Advanced GNSS+ Technologies On-Board:

• AIM+ Anti-Jamming & Anti-Spoofing: Advanced RF spectrum monitoring and interference mitigation to secure your critical navigation data against intentional or environmental jamming.
• LOCK+ Vibration Mitigation: Maintains robust satellite tracking loop tracking even under extreme mechanical shocks or high-vibration drone flight conditions.
• APME+ Multipath Mitigation: Minimizes signal reflections from surrounding metal structures, buildings, or vehicles to preserve centimeter-level RTK reliability.
• IONO+ Scintillation Protection: Advanced defense algorithms against ionospheric disturbances, crucial for absolute precision in equatorial or high-latitude environments.

Seamless Integration for Autopilots and Robotics

The mosaic-H ecosystem is fully optimized for modern robotic and unmanned control architectures. With native driver support for PX4 Autopilot, ArduPilot, and ROS/ROSaic environments, these boards seamlessly inject "GPS for Yaw" directly into your flight controllers. Whether you are assembling a survey-grade drone, an autonomous tractor using AgOpenGPS, or heavy industrial machinery, the mosaic-H delivers unparalleled price-to-performance in an SMD footprint.
