CUAV C-RTK 3 X20P High-Precision GNSS RTK Receiver
Description:
C-RTK 3 X20P is an integrated positioning module that combines professional-grade positioning, industrial-grade attitude perception, and multi-layered safety protection. The core relies on the u-blox X20 all-band GNSS platform, which supports concurrent reception across all constellations and all bands, and achieves centimeter-level positioning accuracy through RTK/PPP-RTK technology. It integrates a high-performance STM32H523 processor and an RM3100 three-axis electronic compass, and supports high-speed communication with DroneCAN/CAN FD. It adopts a compact design, a wide-temperature design, and end-to-end security protection. It can meet the integration requirements of harsh industrial environments and small equipment, providing highly reliable, plug-and-play precision positioning services for high-end scenarios such as unmanned systems and industrial automation.
Full-Dimension and Precise Positioning | Excellent Accuracy
C-RTK 3 X20P achieves a breakthrough in accuracy through multi-mode positioning technology. It can meet the application requirements from the centimeter to decimeter level. Its convergence speed is excellent, and with a high navigation update rate of 25Hz, it can accurately capture position changes in high-speed dynamic scenarios, providing reliable data support for real-time control devices.
All-Band and All-Constellation Coverage | Capture Signals Accurately
The module fully covers the L1/L2/L5/L6/L-band frequency bands and supports concurrent reception of six major global satellite constellations: GPS, Galileo, BeiDou, GLONASS, QZSS, and NavIC. This is significantly improving signal acquisition capabilities. The combined design of multi-constellation and multi-band effectively reduces the impact of signal obstruction in complex environments such as urban canyons, mountains, and forests, and maintains stable positioning even in weak-signal scenarios, thereby expanding the range of applications.
Industrial-Grade Strong Adaptability | Undeterred by Harsh Environments
Adhering to industrial-grade design standards, the module operates in a temperature range of -15℃ to +85℃, easily coping with extreme environments such as high temperatures and extreme cold. Its anti-vibration meets the MIL-STD-810G standard (7.7g RMS) and is suitable for high-frequency vibration scenarios such as vehicles, agricultural machinery, and industrial robots.
High-Integrated and High-Compatible Design | One-Stop Efficient Solution
C-RTK 3 X20P adopts a highly integrated solution, with a built-in X20 RTK full-band receiver, RM3100 industrial-grade electronic compass, and STM32H5 processor. It is also compatible with u-blox AssistNow Live Orbits accelerated startup service, PointPerfect global calibration service, and SBAS satellite augmentation system, enabling users to enjoy value-added functions without additional development, shortening product development cycle, and helping products to be launched quickly
End-to-End Full-Link Security Protection | Multiple Anti-Jamming Protection
- With a built-in spectrum analyzer, it monitors RF environmental interference in real time and dynamically optimizes the reception strategy. The noise figure in the L1/B1/E1 bands is as low as 6.5dB, providing a strong capability to recived week signals.
- It supports Galileo OSNMA navigation message authentication, identifies spoofed satellite signals, and prevents positioning data deception. At the hardware level, it features a secure boot function that executes only legitimate firmware signed by u-blox. Combined with an encrypted storage area design, it can prevent malicious code injection and sensitive data leakage, comprehensively ensuring the security of the positioning system.
Multi-Device Compatibility | Standardized Positioning Calibration
- It has a rich interface configuration, supports multiple communication methods such as DroneCAN, UART, and USB, and can be flexibly adapted to different hardware systems. The device driver has been pre-adapted and supports the built-in magnetic calibration and positioning calibration processes of the platform. It can be plug-and-play.
- It supports UART/CAN interfaces and can be flexibly adapted to different hardware systems. It is widely applicable to scenarios requiring precise positioning, such as intelligent driving, agricultural machinery navigation, robots, and unmanned systems.
