CUAV C-RTK 2 HP GNSS Heading Module

The CUAV C-RTK 2 HP is a high-performance dual-antenna GNSS RTK module engineered to deliver precise heading and centimetre-level positioning for industrial, agricultural, and heavy-lift drones. By calculating yaw through the phase difference between dual GNSS antennas rather than relying on a traditional magnetic compass, it completely bypasses magnetic interference from high-current power cables, large motors, or metal-heavy payloads. This makes it a critical navigational upgrade for ArduPilot and PX4 builds operating in electromagnetically noisy environments.

Key features

• Dual-antenna heading calculation provides true yaw data independent of local magnetic fields, eliminating toilet-bowl effects.

• Centimetre-level RTK positioning accuracy for surveying, 3D mapping, and precision agriculture flights.

• Multi-band, multi-constellation GNSS reception ensures fast satellite locks and robust signal retention even in challenging skies.

• Supports reliable DroneCAN and standard UART communication for straightforward integration with Pixhawk, Cube, and other commercial flight controllers.

Specifications

• Receiver type: Dual-antenna RTK Heading & Positioning

• Supported constellations: GPS, GLONASS, Galileo, BeiDou

• Interfaces: DroneCAN, UART, USB

• Input voltage: 4.5V - 5.5V

• Supported firmware: ArduPilot, PX4

Ideal for complex X-Class, cinelifter, and VTOL builds where compass interference previously caused heading drift, the C-RTK 2 HP provides a rock-solid, interference-proof navigational foundation.
