COSPAS-SARSAT system of GMDSS plays a key role . EPIRB which is part of the system directly related to safety of shipping .

全球海上遇险和安全系统中的全球卫星搜救系统发挥着关键作用，应急无线示位标作为其中重要的组成部分，其运行的情况直接关系到船舶安全。

The section also describes the data protocol of EPIRB , encoding and decoding principles of BCH codes , provide a theoretical basis for the accuracy of the test datas .

该部分还介绍了EPIRB的数据协议和BCH码的编译码原理，为测试数据的准确性提供理论依据。

This paper describes how to design a low-cost 406MHz / EPIRB test receiver , which can be used for routine testing and maintenance of the EPIRB .

本文研究设计一种低成本的406MHz/EPIRB测试接收设备，可供船舶作EPIRB的日常检测和维护使用。

As the testing equipment , EPIRB tester is responsible for the important work to assess the performance of EPIRB . Firstly , the frequency detecting indexes of the beacon are introduced .

示位标检测仪作为专属检测仪器，担负着评定应急示位标性能指标的重要任务。本文首先对示位标的短期频率稳定度指标以及EPIRB检测仪的基本结构进行了介绍与分析。

Emergency Position Indicating Radio Beacon ( EPIRB ) is an important part of the global maritime distress safety systems ( GMDSS ), which has been widely applied in the emergency communication of sea vessel .

应急示位标（EPIRB）是全球海上遇险安全系统（GMDSS）的重要组成部分，现已被广泛应用于航海船只的应急通信中。

As the incident happened Graham sent a radio distress call and activated the EPIRB ( a GPS beacon ) but they were immediately forced to abandon ship , McGregor said in an interview .

麦格雷戈在接受采访时表示：事故发生后，格雷厄姆立刻发出遇险无线电求救信号，启动了应急无线电示位标，但他们立刻需要弃船逃生。

The principle of this design consists of three parts : firstly , using the IF digital demodulation technique which can demodulate the receiving the radio signals sending by EPIRB ; secondly , decoding the protocol data ; finally displaying and printing the preset information of the EPIRB .

其基本原理是接收EPIRB发射的无线电信号，采用中频数字解调技术进行解调，对协议数据进行解析，并进行EPIRB预置信息的显示和打印。
