Positional devices can be broadly divided into two categories:
Global Positioning System technology, also known as GPS, is the main source of identifying and/or monitoring the whereabouts of yachts and their crew all over the world's oceans.
GPS is a satellite navigation system which determines the position of a yacht or a member of crew anywhere in the world.
The system consists of 24 evenly spaced satellites which orbit the earth once every 12 hours at high speed resulting in direct line-of-sight to four of those satellites at any one time from anywhere on the globe.
Each satellite broadcasts a signal that includes current position, orbit, and exact time.
A GPS receiver triangulates the signals from a minimum three, optimum four satellites to determine the receiver's position with extraordinary accuracy. Even allowing for satellite geometry, signal blockage and atmospheric conditions, most GPS receivers can attain results to within a 100metre radius.
EPIRBs and PLBs use Global Positioning System technology to pinpoint the exact position of a yacht or individual in distress.
EPIRB stands for Emergency Position Indicating Radio Beacon - PLB stands for Personal Locator Beacon.
EPIRBs and PLBs transmit their emergency signals on the 406MHz distress frequency via the free to use, multi-national Cospas Sarsat network.
PLBs can also have LAS (Local Area System) capability which transmits a homing signal on 121.5MHz to the Search and Rescue services e.g. ACR ResQlink View
Jimmy Green offer the McMurdo G8 AIS Smartfind EPIRB which transmits a man overboard alarm alert on AIS VHF frequency to any AIS enabled vessel up to four nautical miles, dependent on sea state and aerial height.
Device | Registration | Application | Activation | Battery Life | Buoyancy |
---|---|---|---|---|---|
PLB | Registered to an individual | Outdoor on land and sea | Manual activation | minimum 24 hours | Some float, some require a buoyant pouch |
EPIRB | Registered to a vessel | at sea only | Manual or automatic activation | minimum 48 hours | All EPIRBs float |
AIS Beacons are manually activated location devices which transmit the man overboard location to any yacht or ship's chart plotter up to four nautical miles, dependent on sea state and aerial height
OLAS stands for Overboard Location Alert System which uses Bluetooth, mobile app technology and GPS to sound the man overboard alarm and help the remaining crew onboard to navigate a yacht back to the casualty.There are thre main navigational aids to avoiding collision at sea:
