C-RTK 3 X20P GNSS Module Product Description:
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.
