ARK Electronics has introduced its new ARK G5 RTK GPS and ARK G5 RTK Heading GPS modules, expanding its portfolio of high-performance, NDAA-compliant navigation solutions for unmanned and autonomous platforms.
The ARK G5 RTK Heading GPS is positioned as the first Made in the USA, NDAA-compliant dual-antenna GPS to provide true heading capability, addressing a critical requirement for defense, government, and commercial UAS operators.
Based on the Septentrio mosaic-G5 P3H receiver, the module delivers quad-band, multi-constellation GNSS tracking with centimeter-level RTK accuracy and a 20 Hz update rate. Dual-antenna heading is supported using triple-band GNSS, while configurations allow operation in either single- or dual-antenna modes.
Alongside GNSS and heading functionality, the Heading variant integrates a ST IIS2MDC magnetometer, Bosch BMP390 barometer, Invensense ICM-42688-P 6-axis IMU, onboard buzzer, and an STM32F412 MCU. DroneCAN connectivity enables seamless integration with Pixhawk-based autopilots and supports firmware updates over CAN.
The standard ARK G5 RTK GPS shares the same compact form factor and sensor suite, utilizing the mosaic-G5 P3 receiver to deliver high-precision RTK positioning without heading capability. Both modules feature ultra-compact dimensions, low power consumption, and Pixhawk Standard CAN interfaces.
Manufactured and assembled in the United States, the ARK G5 RTK series is designed to meet the needs of mission-critical unmanned systems requiring assured supply chains, regulatory compliance, and precision navigation performance.
