vii [READ THIS FIRST!!] IMPORTANT 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 groundtracking is unattainable. To achieve reliable measu...

viii CALIBRATING COURSE OFFSET (Automatic) A. When ground-tracking is attainable: 1. Make sure the navaid (GPS) is working correctly and accurately. 2. On CI-35/35H, select ground tracking mode. (Press the TRACKING MODE key to see the “GT” mode indication on the display.) 3. In Menu 4, set ‘CRS CAL ...

ix WHY IS GYRO DATA IMPORTANT IN NAV-AIDED MODE? If you consider the difference of tide vector calculations is ground-tracking mode and in nav-aidedmode, you will realize how important the gyro (heading) information is. Tide Calculation in Ground-Tracking Mode In ground-tracking mode, the CI-35/35H ...

x Tide 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 b...

1-2 2. PRINCIPLE OF MEASUREMENT When a moving vessel emits an acoustical pulse into the water at an angle, a portion of emittedenergy 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 t...

1-3 Tide Tide is movement of watermass at a particular depth. To 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 difference of these two spee...

1-4 Tide Differential Tide differential is a relative movement of tides at different depths, layer (A) and layer (B). To calculate tide differential, the following two data are used: 1 Ship’s speed and course based on layer (A) 2 Ship’s speed and course based on layer (B) Tide differential between t...

1-6 Tide Differential Tide differential is a relative movement of tides at different depths. It can be measured in the ground tracking, water tracking and nav-aided modes. :Base of measurement w e Layer A Start oftrip End oftrip (Moving) 10 NM (1 hour trip) Layer B (Moving) 2 kt 5 kt Assuming that t...

1-7 Cd = C1 - C2= (Vg - Vwa) - (Vg - Vwb)= Vwb - Vwa= 5 - 8= -3 (kt) In the water tracking mode, watermass just below the transducer (near-surface layer) is taken as thebase of all measurements (virtual ground). Therefore, the ship and tide speeds in the water trackingmode are not absolute but relat...

1-8 Tide differential calculations in water tracking mode Tide speeds of layer A (C1) and layer B (C2) relative to near-surface layer (Vw) are calculated asfollows: D1 = Vw - Vwa (Speed of layer A based on near-surface layer) D2 = Vw - Vwb (Speed of layer B based on near-surface layer) The tide diff...
