EPIRBs are designed specifically for maritime applications. They quickly alert authorities as to the whereabouts of distressed vessels and their crews, while PLBs (as their name suggests) alert authorised as to the whereabouts of individuals. PLBs are suitable for use in a range of applications, including bush walking, 4×4 driving and remote work. A GPS enabled 406 EPIRB's accuracy is roughly within 100 yards of the initial alert which is a vast improvement from the old 121.5 MHz EPIRBs. Once registered and in the event of an activation, the unique encoded digital message is received by the satellites are then transmitted back to ground-based search and rescue authorities. Ship radio uses medium frequency (MF), very high frequency (VHF), high frequency (HF), and ultra high frequency (UHF) radio equipment. It can also use satellite communications equipment, radar equipment, emergency position indicating radio beacons (EPIRB), and search and rescue transponders (SART). Featured content Let's compare several latest SART models of different makers and see what is stated in their manuals. 1. Maker: Jotron; Model: Tron SART20 "Tron SART20 requires the following maintenance: At least every 6 months. The transponder should be taken out of its bracket and tested against a radar, using the procedure … Explanation on the types of EPIRB, frequency of operation, testing, mandatory certification requirements as per IMO and Solas and also regarding SART operations and its testing procedures. fPvzD.
