== Summary ==<br />
The ZED-F9P GPS-RTK HAT is a precision GNSS module with RTK capability that connects to a Raspberry Pi via UART. It supports multiple satellite systems and frequency bands, enables centimeter-level accuracy in RTK mode, and can operate as either a rover or a base station.<br />

== Notes and version constraints ==<br />
* The demo commands use test credentials from a specific NTRIP service; other regions require their own account details.<br />
* For Windows PC usage, u-center must be installed; the exact steps depend on the chosen base-station provider.<br />
* The “Moving Base and Rover” section lacks configuration details for the MB module; additional information from the full manual is needed.<br />
* The listed commands assume the hardware serial port has been enabled on the Raspberry Pi.<br />
