GPS - Global Positioning System
The Global Positioning System (GPS) is the basis of all electronic navigation systems. GPS information from satellites gives constant updates on chart plotters.
GPS chart plotters show position plus 'speed over the ground' and 'distance to target'. This information can be integrated with radar and depth information on one display.
Radar - Radio Detection and Ranging
Radar is an object detection system that uses electromagnetic waves to identify the range, altitude, direction and speed of both moving and fixed objects.
The returning signal can be amplified through use of electronic techniques in the radar receiver to identify ships, aircraft, weather formations and land masses.
Depth Sounders - Underwater Imaging
Transducers are mounted internally or externally using single beam, dual beam and quad beam sonar to give a visual display of underwater features and hazards.
Sonar returns from these beams or waves measure depth below the craft. Using new technology the sonar can provide underwater side imaging and a view ahead.
AIS - Automatic Identification System
The Automatic Identification System (AIS) is a short range coastal tracking system used on ships and by Vessel Traffic Services (VTS) to electronically identify vessels.
Unique vessel identification, position, course and speed information can be displayed which allows maritime authorities to track and monitor vessel movements.
Gauges & Instruments
Marine gauges and instuments can be digital or analogue units with separate or multiple readouts. Gauges include volts, water temperature, oil pressure and fuel level.
Marine gauges need to be able to withstand the movement and vibration on RIBs and High Speed Craft. They also require highly visible number graphics and backlighting.
Imaging & Display
PCs and displays are required for a wide range of marine applications including chart plotting, radar overlay, engine monitoring, instrumentation, weatherfax and sonar.
Imaging is used for various marine security and surveillance applications including port security, night vision, thermal imaging, low-light CCTV and laser rangefinding.
The objective in the RIB and High Speed Craft sector is to reduce the effects of Whole Body Vibration (WBV). The EC Vibration Directive came into force on 6th July 2010.
Military, coastguard, federal and commercial organisations need vibration monitoring to identify and qauntify the problem. SED8 retates to vibration dose over a time period.
Intercom systems are required for communication between crew members. Systems can use hard wired or wireless equipment that allows crew to board other vessels.
External Radio Communication
External marine radio communication is usually by VHF radio. Headsets combine speakers and microphones which can also be incorporated into helmets.
Combined transmitters and receivers operate on standard international frequencies known as channels. "Simplex" allows communication in one direction at a time.
Digital Selective Calling (DSC)
"Digital Selective Calling" (DSC) capability allows a distress signal to be sent with a single button press. Can be integrated with onboard GPS to transmit position.
High aerials give a “ship to ship” range of 50 nm (90 km). Range between small boats is approximately 5 nautical miles (9 km). Output power ranges from 1W to 25W.
Boarding Team Communications
New technology enables crews to board other vessels with the option to talk "radio to radio" or to a wider network, including the boarding team boat and mother vessel.
