项目摘要

Four countries, the U. S. A., the Soviet Union, French and Canada, are discussing on the world-wide satellite system for search and rescue by means of COSPAS SARSAT ; satellite EPIRB which is aimed to put to practical use. But, this system contain only the distress signal calculate the position at the distress area on basis of signal on satellite, and do not contain the most important informations of the survivors.We have experiments for the advance search and rescue system via stationary mobile communications satellite ; ETS-5 called KIKU-5. This experimental system uses a victim survival checking sensor (ECG) with life jacket, and gets position with recieving GPS satellite signals on the buoy. The buoy scans automatically from 420 to 44OMHz and demodulates ECG signal, sends vital information and navigation informations back to the stational communications satellite as packet signal.This system has the following characteristics.1. Communication range is wide.2.24 hour operation is possible.3. Two way communications possible.4. Contains victim vital informations.5. Locationing precision is relativry good (+/-10m).COSPAS-SARSAT system has no information about rescue, so it can hardly be called appropriate for triage and acute treatment after disasters. With this experimental system, it is possible to transm vital reaction faith fully, to confirm the location at a remote place in real time over 24 hours. It seems very useful, quite practical, and feasible to save human being after disaster as new search and rescue systems.

四个国家，美国。S.一、苏联、法国和加拿大正在讨论通过COSPAS SARSAT建立世界范围的搜索和救援卫星系统;卫星应急无线电示位标，目的是投入实际使用。但是，这个系统只包含遇险信号计算在卫星上的信号的基础上在遇险区域的位置，并不包含最重要的信息的幸存者。我们有实验的先进搜索和救援系统通过固定的移动的通信卫星; ETS-5称为KIKU-5。该实验系统采用救生衣上的遇难者生存检测传感器（ECG），通过接收浮标上的GPS卫星信号进行定位。该浮标能自动在420 ~ 440 MHz频率范围内对心电信号进行扫描，并将生命信息和导航信息以分组信号的形式发送回北斗通信卫星，具有以下特点.通讯范围广。2.可24小时工作。双向通信可能。4.包含受害者的重要信息。COSPAS-SARSAT系统定位精度较好（± 10 m），但由于没有救援信息，因此很难称为适合灾后分诊和急救。利用该实验系统，可以在24小时内对生命反应进行全面的、真实的实时的远程定位。作为一种新型的搜救系统，对灾后人员的救助具有很强的实用性和可行性。
