产品规格 Transmitting a distress alert either through the polar orbiting satellite service, operating in the 406 MHz band, or through the INMARSAT geostationary satellite service operating in the 1.6 GHz band. The unit will also float free if the ship sinks and will be automatically activated when afloat or activated manually in emergency. The EPIRB mentioned here is operated on 406 MHz and 121.5 MHz by the COSPAS/SARSAT satellite system which is adopted widely to the ships in the early stage of the introduction of the GMDSS. This type of EPIRB will broadcast on 406 MHz to be received by the COSPAS/SARSAT satellite and on 121.5 MHz to be used for homing by search-and-rescue vessels along with a strobe to pinpoint exact location. It is required, when ordering, to specify the ship’s registered flag, call sign, etc. to be programmed into the EPIRB as a rescue signal by the manufacturer before delivery.
中文汉化 372511 卫星应急无线电示位标，406MHz/121.5MHz 它通过在406MHz频段运行的极轨道卫星服务或在1.6GHz频段运行的INMARSAT地球静止卫星服务发送遇险警报。如果船舶沉没，该设备会自由漂浮，并且在水上时自动激活，或者在紧急情况下手动激活。这里的EPIRB由COSPAS/SARSAT卫星系统操作，这是在GMDSS引入初期广泛采用于船舶的系统。这种类型的EPIRB会在406MHz频率上广播，供COSPAS/SARSAT卫星接收，并在121.5MHz频率上工作，以便搜救船只定位，同时配备有频闪灯以精确标识位置。在下订单时，必须指定船舶的登记旗帜、呼号等信息，由制造商在交付前预编程到EPIRB中作为求救信号。
