F2 Fibre Optics The F2 Fibre Optic Pack is standard fit to the Falcon DR and an optional upgrade for standard Falcons. It provides the addition of a subsea andsurface fibre optic multiplexer and a suitable umbilical for transmission of video and data over fibre optics between the surface and the vehicle. The benefits of the F2 Fibre Optic Packinclude:•14 mm low drag twin pass fibre optic umbilical •Spare fibre optic pass •2 x RS 485 (1 spare) and 4 spare RS 232 bi-directional channels •3 Simultaneous video channels •Ability to use broadcast quality video cameras•Extended ROV excursions to 1600 mor more with custom umbilicals. Nav Specifications Boat navigation system & Auto Functions Compass Accuracy ±0.5° Depth Sensor Accuracy ±0.5% of FSD Gyro 0.1 °/s Surface Update Rate <40 mS Optional Auto Altitude All navigation sensors and aids are housed in a single hardened aluminium pod. Auto depth and heading are standard fit with auto altitude offered as an option. Apitch and roll sensor is included and may be selected for display on the video overlay. Lighting Two forward facing variable intensity 75 Watt Tungsten Halogen flood lights are fitted. An optional additional light can be added. The lights are powered at low voltage, to improve reliability and longevity. In the Falcon DR the forward facing lights tilt with the camera forimproved scene illumination. HID lights are offered as an option. Camera System Ahigh resolution fixed focus colour camera is fitted to a camera platform that can be tilted ±90 degrees. An additional switched camera can be added. The F2 Fibre Optic Pack in Falcon DR which is optional in standard Falcons, provides 3 simultaneous video channels. Panning the camera is achieved by turning the vehicle which it can do within its own length. Standard Camera Specification Camera Resolution 480 TVL Min. Scene Illumination 0.2 LUX (F1.4) Pick Up Device 1/2" CCD Image Sensor Lens 1/2" Aspherical 3.8mm lens, wide angle fixed focus Horizontal Field of View 91° Tilt ±90° Umbilical Cable & Winch Options Achoice of neutrally buoyant or thinner, slightly heavy umbilical cable is offered. These light weight proprietary jacketed cables offer high abrasion resistance and incorporate a Vectran strength member. Achoice of hand operated winches are available including a compact wheeled Pelican case housed winch that can accommodate a useful 295 metres of 11 mm diameter umbilical. Electric winches are available for the longest umbilical lengths. All have appropriate slip rings to marine suit the umbilical type. SURFACE EQUIPMENT Input Power Requirements: Single phase universal auto sensing input, 100-270 VAC at 2.8 kW. Falcon Surface Units The Falcon’s switch mode power supplies, control system, fold out 17 inch LCD monitor and keyboard are installed in a 19 inch rack transport case. All connections to the surface unit are onthe front panel for easy access including the hand controller with its 5 metre flying lead. The power output from the surface unit to the umbilical is a galvanically isolated 500 VDC protected by a L.I.M. An optional IP68 waterproof surface unitis available and is particularly popular with military users. Vehicle Controls on the Hand ControlUnit The following vehicle controls are provided on the hand controller:• Single 3 axis joystick for horizontal vehicle control• Rotary trim controller for vertical thrust up or down• Push button dive and surface control • Marine thruster enable / disable and power setting• Camera selection • Rotary control for lights intensity • Auto pilot function for both heading and depth • Auxiliary vehicle controls (including manipulator open / close). Avideo overlay system is incorporated asstandard providing the following information to the pilot:•Compass heading •Depth •Camera tilt position •Auto pilot function status •Umbilical turns counter • Vehicle pitch and roll • CPreading • Date and time •Free text using a QWERTYkeyboard.
