Speed Log · Position & Heading
Kongsberg DPS 120 Doppler Log is a marine Speed Log (Doppler) within the Position & Heading group. Equipment of this type is typically installed on or around the bridge, with sensors, antennas or remote units positioned where they can obtain the required ship or environmental data. Its primary duty is the vessel function associated with the Speed Log (Doppler), supplying information or records needed for navigation, monitoring or regulatory operation, and it depends on its primary sensor or input device, processing unit, shipboard interfaces and power supply remaining correctly connected and configured. Neighboring variants can differ in rating, size, interface, approval basis or arrangement, so the complete model designation and actual nameplate data are important for identification. It normally interfaces with bridge power, the relevant sensors or antennas, navigation data networks and alarm or recording interfaces as fitted.
