C-RTK 9Ps: Genuine CUAV Precision GNSS Hardware

This is a genuine CUAV C-RTK 9Ps, clearly branded on the module itself, built around the u-blox ZED-F9P — a real 184-channel receiver capable of tracking GPS, GLONASS, Galileo, BeiDou, and QZSS constellations concurrently. With RTK corrections, it delivers genuine centimeter-level accuracy (0.01m + 1ppm CEP), updating position at up to 20Hz, with a base station survey-in time under 60 seconds and a cold start under 24 seconds — fast enough to be practical for real field use, not just a lab demo figure.

Beyond single-point positioning, two C-RTK 9Ps modules can work together for dual-antenna RTK heading, reaching roughly 0.4° accuracy — a genuinely useful feature for reducing reliance on a traditional magnetic compass, which can drift or misread near power lines, motors, or other sources of electromagnetic interference. It connects over 2 UART, 1 USB, and 1 I2C interface using standard NMEA, UBX Binary, and RTCM 3.x protocols, and is compatible with both PX4 and ArduPilot. One limitation worth knowing upfront: this module does not support PPK (post-processed kinematic) logging, so it’s built for real-time RTK use rather than post-flight data correction workflows.
