    vii [READ THIS FIRST!!] IMPORT ANT NOTICE ON TIDE MEASUREMENTS (In nav-aided mode, tide accuracy depends heavily on gyro accuracy .) SETTING SHIP’S HEADING The CI-35/35H has the nav-aided mode to measure absolute tides even in deep waters where ground tracking is unattainable. T o achieve reliable measurements, however , you must supply accurate ...

    ix WHY IS GYRO DA T A IMPORT ANT IN NA V -AIDED MODE? If you consider the difference of tide vector calculations is ground-tracking mode and in nav-aided mode, you will realize how important the gyro (heading) information is. T ide Calculation in Ground-T racking Mode In ground-tracking mode, the CI-35/35H derives tide information from the followin ...

  • Furuno CI-35 - page 12

    x T ide Calculation in Nav-Aided Mode In nav-aided mode, the CI-35/35H derives tide information from the following data. (1) Ship’ s speed/course sensed by the external navigator (GPS) (nav speed = pseudo ground speed) (2) Ship’ s speed/course based on target layer (water speed) (3) Bearing of ship’ s bow (Heading by gyro) Here, nav speed (1) ...

    1-1 CHAPTER 1. GENERAL 1. FEA TURES ¡ The functions of CI-35 and CI-35H are same. CI-35H is type approved by MOT (Ministory of T ransportation). ¡ Even in deep waters where ground (bottom) reference is not available acoustically , the CI-35/ 35H can provide absolute movements of measuring layers by receiving position (or speed) data from GPS navi ...

    1-2 2. PRINCIPLE OF MEASUREMENT When a moving vessel emits an acoustical pulse into the water at an angle, a portion of emitted energy is reflected from the seabed and other microscopic objects in the sound path, such as plank- ton or air bubbles. The frequency of the received signal is shifted from the transmitted frequency in proportion to relati ...

    1-3 Tide T ide is movement of watermass at a particular depth. T o know absolute tide (speed on ground), the following two data are required: 1 Ship’ s speed and course based on ground 2 Ship’ s speed and course based on measuring layer (A) Absolute tide is, then, given as a dif ference of these two speed vectors. Absolute T ide = 1 - 2 Fixed L ...

Therefore, the ship and tide speeds in the water tracking mode are not absolute but relative to this near -surface layer . Vw = 9 kt ...

Documents that we receive from a manufacturer of a Furuno CI-35 can be divided into several groups. They are, among others:
- Furuno technical drawings
- CI-35 manuals
- Furuno product data sheets
- information booklets
