Description

The C-RTK 2 module integrates u-blox’s flagship ZED-F9P GNSS module with a powerful STM32H743VIH6 processor and a suite of high-fidelity sensors. This combination delivers robust, centimeter-accurate positioning essential for demanding applications like photogrammetry, topographic mapping, and precision agriculture. The module supports both real-time RTK corrections and PPK workflows, offering flexibility in post-processing for maximum accuracy.

Designed for seamless integration, it communicates via UAVCAN/DroneCAN and includes dedicated ports for hotshoe and mechanical shutter triggers, enabling precise geotagging of aerial imagery. Its compact form factor (56x33mm) and low weight (39g) make it suitable for a wide range of multirotor, VTOL, and helicopter platforms without compromising payload capacity.

Key Features

  • Multi-Constellation, Multi-Frequency Receiver: Tracks GPS (L1C/A, L2C), GLONASS (L1OF, L2OF), Galileo (E1B/C, E5b), and BeiDou (B1I, B2I) bands for superior availability and resilience.
  • High-Update Rate Logging: Supports RTK update rates up to 20 Hz and raw data logging (PPK) up to 25 Hz for capturing dynamic flight paths.
  • Industrial-Grade Durability: Operates reliably across an extended temperature range from -20°C to +85°C.
  • Plug-and-Play Compatibility: Designed for direct connection with CUAV X7 flight controllers and full protocol compatibility with ArduPilot and PX4 firmware.
  • Onboard Data Storage: Features a microSD card slot supporting up to 32GB for autonomous logging of raw observation data.
  • Comprehensive I/O: Provides HS_USB, U-disk mode, and multiple dedicated trigger interfaces for camera control.

Applications

  • Aerial Surveying & Mapping Drones for photogrammetry and LiDAR payloads.
  • Precision Agriculture platforms for automated crop scouting and spraying.
  • VTOL (Vertical Take-Off and Landing) and fixed-wing UAVs used in corridor mapping.
  • Search and Rescue (SAR) or inspection drones requiring precise, repeatable positioning.
  • High-altitude or long-endurance platforms where GNSS signal reliability is critical.

Frequently Asked Questions

What is the difference between RTK and PPK modes on the C-RTK 2?

The C-RTK 2 supports both modes simultaneously. RTK (Real-Time Kinematic) provides centimeter-level accuracy in real-time by using a correction data stream from a base station. PPK (Post-Processed Kinematic) logs raw GNSS observation data to an onboard microSD card for higher-accuracy post-processing after the flight, which is more reliable in areas with poor communication links.

Is the CUAV C-RTK 2 compatible with my Pixhawk 6X or other flight controllers?

Yes, the module is designed for broad compatibility. It connects via UAVCAN/DroneCAN, a standardized protocol supported by modern flight controllers like the Pixhawk 6X, CUAV X7, and others running ArduPilot or PX4 firmware. The included CAN cable provides the physical connection, and configuration is handled within the ground control station software.

What power supply does the C-RTK 2 module require?

The module operates on a voltage range of 4.5V to 6V DC. It is typically powered from a regulated 5V BEC on the flight controller or power distribution board. Ensuring a clean, stable power supply within this range is crucial for optimal performance of the sensitive GNSS and IMU components.

How do I connect a camera for geotagging with this module?

The C-RTK 2 includes multiple trigger cables (Canon 2.5mm, Sony USB, and a Generic shutter cable) and a Hotshoe PCB. You connect the appropriate cable from the module's trigger port to your camera's remote port. The flight controller can then send a trigger command synchronized with the precise GNSS position, enabling accurate geotagging for each captured image.
