Professional surveyors, drone operators, and roboticists use this module to achieve accurate attitude reference and precise geolocation in challenging environments where standard GPS fails. This product solves the critical problem of obtaining reliable heading and position data simultaneously, eliminating the need for separate compass modules and reducing system complexity in autonomous navigation systems.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe CUAV C-RTK 2 HP operates on the principle of Real-Time Kinematic (RTK) positioning combined with dual-antenna heading calculation. The module receives signals from multiple GNSS constellations including GPS, GLONASS, Galileo, and BeiDou, processing them through advanced algorithms to deliver centimeter-level accuracy. The dual-antenna configuration allows the system to calculate precise heading angles by measuring the baseline vector between two receivers, eliminating magnetic interference issues common in traditional compass-based systems. This architecture makes it ideal for applications where magnetic declination, metal structures, or electromagnetic noise would compromise conventional heading sensors.\u003c\/p\u003e\n\n\u003cp\u003eThe C-RTK 2 HP distinguishes itself through its high-precision RTK engine capable of achieving 2cm horizontal and 3cm vertical accuracy in optimal conditions, combined with heading accuracy of 0.2 degrees or better. The module integrates seamlessly with Pixhawk autopilot systems and supports multiple communication protocols including CAN, serial UART, and USB interfaces. Built-in IMU fusion algorithms enhance performance in signal-degraded environments, while the compact form factor and low power consumption make it suitable for battery-powered autonomous platforms. The module operates across a wide temperature range and includes robust filtering to handle dynamic motion scenarios typical in UAV and ground vehicle applications.\u003c\/p\u003e\n\n\u003ch2\u003eKey

Use\u003c\/h2\u003e\n\u003cp\u003eInstallation of the CUAV C-RTK 2 HP requires careful antenna placement with adequate sky visibility and minimum 30cm baseline separation between the two antennas for optimal heading calculation. Mount the primary antenna at the vehicle's center of gravity and the secondary antenna forward along the longitudinal axis, ensuring both antennas maintain clear line-of-sight to the sky. Connect the module to your autopilot system using CAN or serial UART interface as per your flight controller specifications, then configure the baseline vector parameters in your autopilot firmware to match your physical antenna separation distance and orientation.\u003c\/p\u003e\n\n\u003cp\u003eDuring initial setup, perform a compass calibration procedure specific to RTK heading modules, which typically involves rotating the vehicle in a horizontal plane to allow the system to establish accurate baseline vector measurements. Configure your ground station software to accept RTK corrections from a base station or NTRIP caster service, which is essential for achieving the 2cm accuracy specification. Verify heading output by observing real-time heading values in your autopilot telemetry stream while rotating the vehicle manually. Once operational, the module will automatically blend GNSS position, heading, and IMU data to provide robust navigation estimates suitable for autonomous flight or ground vehicle operation in both open-sky and partially obstructed environments.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the minimum baseline distance required between the two antennas for accurate heading calculation?\u003c\/summary\u003e\n\u003cp\u003eThe CUAV C-RTK 2 HP requires a minimum baseline separation of 30cm between the primary and secondary antennas for reliable heading calculation. Longer baselines improve heading accuracy, with 1-2 meter separations providing optimal performance. The baseline vector must be configured in your autopilot firmware to match your physical antenna placement exactly, as this parameter directly affects heading accuracy. Ensure both antennas maintain equal sky visibility and avoid mounting them at significantly different heights to minimize atmospheric error propagation.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan this module operate without RTK corrections for basic positioning?\u003c\/summary\u003e\n\u003cp\u003eYes, the C-RTK 2 HP can operate in DGPS mode without RTK corrections, achieving approximately 0.5m horizontal and 0.8m vertical accuracy. However, RTK corrections are essential for achieving the 2cm accuracy specification and are highly recommended for autonomous vehicle applications. RTK corrections can be obtained from a local base station, NTRIP caster services, or satellite-based augmentation systems. The module will automatically switch between RTK and DGPS modes based on correction availability, maintaining continuous navigation capability even if RTK service is temporarily unavailable.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow does the C-RTK 2 HP maintain heading accuracy during vehicle acceleration and dynamic maneuvers?\u003c\/summary\u003e\n\u003cp\u003eThe module incorporates IMU fusion algorithms that blend GNSS heading measurements with inertial measurement unit data to maintain accurate heading estimates during dynamic vehicle motion. The integrated accelerometers and gyroscopes provide high-frequency heading updates between GNSS measurement cycles, enabling smooth heading output at the full 20Hz update rate even during aggressive vehicle maneuvers. This fusion approach is particularly valuable during UAV flight when rapid attitude changes occur, ensuring the autopilot receives consistent heading reference for stable flight control.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eOrders are dispatched within 1-5 business days from our Bengaluru warehouse.
