Equipped with a built-in LNA and SAW filter, it has high sensitivity and strong anti-interference capability. Utilising dual-band positioning and RTK technology, it provides centimetre-level high-precision positioning, making it ideal for real-time tracking systems and sharing economy applications, including drones, smart farm machinery, and shared two-wheelers. It supports fast convergence dual-band RTK centimetre-level positioning for high-precision terminal device applications.\u003c\/p\u003e\n\u003cp\u003eThe HAT features a standard Raspberry Pi 40-pin GPIO extension header, providing compatibility with \u003ca href=\"\/zh\/collections\/raspberry-pi-store\"\u003eRaspberry Pi series boards\u003c\/a\u003e and \u003ca href=\"\/zh\/products\/nvidia-jetson-nano-4gb-developer-kit\"\u003eJetson Nano\u003c\/a\u003e.
