GPS Receiver · Position & Heading
JRC (Japan Radio Co) JLR-7900 Multi-GNSS — Position & Heading. As a GPS Receiver, it is normally installed on the bridge or in the navigation electronics system with its required external sensor, antenna or hull interface. In that role, its primary purpose is to provide position, time and motion data for navigation and connected vessel systems. Compared with dead-reckoning sensors, GNSS derives position from satellite signals and depends on antenna visibility, receiver integrity and correct output configuration. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
