C-RTK 9Ps Centimetre-Level GNSS Module

The C-RTK 9Ps is a Multi-star Multi-frequency GNSS system, It also supports dual GPS for yaw which can replace compass，
is useful for flight in complex magnetic environments such as close to power lines. It is a very cost-effective centimeter-level
RTK module compatible with PX4/ ArduPilot open-source flight controllers. It is an ideal choice for UAV mapping, agricultural
applications, high-precision takeoff and landing, ship takeoff and landing and other applications requiring real-time high-
precision navigation
