306 transmits navigation data in standard NMEA message format through a wired serial connection. The microcontroller parses the required positional parameters and relays real-time coordinate updates wirelessly to the mobile device via a low-power Bluetooth communication link. This intermediate layer enables continuous data transmission while maintaining a compact and portable field configuration. The mobile computing integration hub functions as the central processing environment of the system. It receives realtime positional information from the microcontroller, converts geodetic coordinates into the projected mine coordinate reference system, and synchronizes the transformed spatial position with a pre-generated threedimensional ore-grade model. Figure 2: Conceptual bench-level augmented reality ore-grade visualization in an open-pit mine. A fixed RTK GNSS base station provides spatial reference, while a field unit consisting of an RTK GNSS rover, microcontroller, portable power supply, and mobile computing hub enables smart glasses to display color-coded ore-grade polygons directly overlaid on the active bench.
