The XT-GNSS GNSS Heading Module is a compact, high-precision, dual-antenna GNSS receiver designed for advanced automation, navigation, and positioning applications. Built on Septentrio's proven mosaic™ platform, this module delivers centimeter-level RTK accuracy and sub-degree heading performance, making it ideal for UAVs, robotics, autonomous vehicles, rail, logistics, and industrial automation.
With dual-antenna input, XT-GNSS-H provides instant and reliable heading combined with pitch or roll angles, ensuring superior performance in both static and dynamic conditions. Unlike magnet-based sensors, it is immune to interference from surrounding metal, making it a robust solution for demanding environments.
The module supports all major GNSS constellations (GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS) with 448 hardware channels for simultaneous multi-frequency tracking. It integrates Septentrio's GNSS+ technology suite, including:
- AIM+: Advanced anti-jamming and anti-spoofing protection
- LOCK+: Robust tracking under vibration and shocks
- APME+: Multipath mitigation for signal reliability
- IONO+: Protection against ionospheric disturbances
- RAIM+: Receiver Autonomous Integrity Monitoring
- OSNMA support for authentication of Galileo signals
Connectivity is versatile, with 4 UART ports, Ethernet (10/100 Mbps), USB 2.0, SDIO, CAN bus, GPIOs, and PPS output, enabling seamless integration into a wide range of platforms. The module is fully documented and supported by RxTools software for configuration, monitoring, logging, and analysis. Offline processing is available via SDK for Post-Processed Kinematic (PPK) workflows.
