ARK Electronics has unveiled the ARK X20 RTK GPS, a U.S.-built, NDAA-compliant DroneCAN navigation module engineered to deliver uncompromising precision, reliability and security for professional UAV and robotics platforms.
This compact, high-precision all-band, all-global GNSS module operates on multiple bands and integrates high-grade navigation, positioning, and safety capabilities into a single module optimized for demanding mission profiles.
Designed for seamless compatibility with PX4 and leveraging u-blox’s ZED-X20P all-band GNSS receiver, the ARK X20 provides best-in-class accuracy and availability across all global satellite constellations. Advanced positioning technologies including RTK, PPP-RTK and PPP enable centimeter-level performance, expanding operability into environments where traditional GNSS solutions struggle.
The ARK X20 consolidates multiple essential flight-critical sensors and system components into a rugged, space-efficient module:
- u-blox ZED-X20P all-band high-precision GNSS receiver with hardened end-to-end security and 25Hz update rate
- ST IIS2MDC 3-axis magnetometer for reliable heading reference
- Bosch BMP390 barometer for accurate altitude determination
- Invensense ICM-42688-P 6-axis IMU for high-fidelity motion sensing
- Integrated buzzer and safety switch for system status confirmation and pilot interaction
DroneCAN-enabled firmware updating ensures future capability growth and simplifies fleet-level maintenance across autonomous platforms.
Powered by an STM32F412VGH6 MCU, the ARK X20 delivers high compute efficiency with low power draw. Standardized connectors streamline integration into PX4-based systems, including:
- Two Pixhawk-standard CAN connectors
- UART 2 port (TX, RX, PPS, GND)
- I2C expansion interface (5V, SCL, SDA, GND)
- Pixhawk-standard debug connector
Clear LED indication for safety status, GPS fix, RTK state, and system diagnostics provides at-a-glance operational confidence.
In response to evolving procurement regulations, ARK Electronics has engineered the X20 to be fully Made in the USA and NDAA compliant, ensuring suitability for defense, government, and critical infrastructure programs.
