Figure 1. System overview illustrating data flow from the RTK GNSS base station through the rover, processing unit, and mobile integration hub to the smart glass display visualization pipeline. 2.2. End-to-End Data Flow and System Integration The system architecture consists of five primary components operating in a continuous data flow loop: an RTK GNSS base station, an RTK GNSS rover, a microcontroller-based communication bridge, a mobile computing integration hub, and a wearable smart-glass display as shown in Figure. 1. The RTK GNSS base station is deployed at a surveyed reference coordinate within the mine site and continuously transmits differential correction messages in RTCM format. These correction signals are received by the RTK GNSS rover, which simultaneously tracks satellite observations and processes carrier-phase measurements to compute real-time geodetic positioning. The rover outputs navigation data including latitude, longitude, ellipsoidal height, satellite status, and positioning quality indicators. A compact microcontroller-based communication bridge provides the interface between the rover and the mobile computing unit. The rover 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 real-time 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 three-dimensional ore-grade model.
