  4. Navigatingin the 21stCentury… The NAVIKNOT Multisensor Speed Log Series utilizes satellite-based technology (GPS) in addition to the traditional electromagnetic sensors and Doppler transducers to provide high-accuracy displays of: • Dual-axis ground speed • and • Single-axis water speed Northrop Grumman Private/Proprietary Level I

  5. Speed Log Operating Principle

  6. Electromagnetic Sensor Operating Principle (Single-Axis Water Speed) The electromagnetic sensor houses a coil which, when energized with an AC current, produces a magnetic field around the sensor in the surrounding water. The ship’s motion through the water produces an electrical field (E) perpendicular to the magnetic field (B) and the ship’s motion (V). The resulting signal is picked up by the sensor electrodes and fed to the preamplifier where it is converted into a digital format and transmitted to the NAVIKNOT electronics unit.

  7. Doppler Transducer Operating Principle (Single-Axis Water Speed) The Doppler transducer utilizes the Doppler frequency shift effect to determine the speed of a vessel through water. The transducer emits 2Mhz frequency sound pulses in the fore and aft directions through two transmitter windows. Two receiver windows in the transducer detect the return echo of the sound pulses. A time delay between pulse transmissions ensures that echoes are received from the undisturbed water outside the vessel’s boundary layer. The signals are processed to determine the ship’s fore/aft speed vector. The preamplifier transmits the speed information in a digital format to the NAVIKNOT electronics unit.

  8. Satellite Sensor Operating Principle (Dual-Axis Ground Speed) The satellite sensor makes use of GPS satellite signals to determine a ship’s longitudinal and transverse ground speeds. A dual antenna unit with two GPS receivers and three rate gyros integrated in an electronics unit determine a vessel’s heading, velocity and course. While the heading is referenced to the ship’s fore-and-aft line, the velocity and course represent the motion vector, i.e. the magnitude and direction of motion over ground. The information received from the satellites is processed in the electronics unit, which resolves the velocity data into the ship’s longitudinal and transverse ground speeds. The speed vectors combined with the rate-of-turn data are used to discern between translational and rotational movement of the vessel. These are used to determine the bow and stern transverse speeds shown in the docking display. Northrop Grumman Private/Proprietary Level I
