基于SCOUT+超短基线定位系统的海上失事飞机黑匣子探测方法

The detection method of wrecked plane's black box based on SCOUT+ ultrashort baseline positioning system

失事飞机黑匣子是空难见证者,一旦落入海中需要快速准确打捞.利用Sonardyne公司生产的SCOUT+超短基线定位系统(USBL)中水深测位仪(pinger)模式,进行黑匣子模拟器的快速搜寻打捞.在20 m水深海洋环境中,对黑匣子模拟器进行搜寻定位,平面位置定位精度达到6.35 m,角度交会定位精度达到2.78°.剔除仪器安装固定误差后,角度精度达到0.40°.由此结果表明:SCOUT+超短基线的黑匣子搜寻探测精度达到预计要求,能够达到实际需求.

The black box of wrecked aircraft,as the witness of air disaster,need to be salvaged quickly.In the ocean environment of twenty meters deepth,we search to locate the aircraft black box based on SCOUT+ultra-short baseline positioning system(USBL).The black box simulator is located in 20 m water depth ocean environment.The positioning accuracy reaches 6.35 m,and the angle positioning accuracy reaches 2.78°.After eliminating the fixed error of installation,the angle positioning accuracy reaches 0.40°.In general,the SCOUT+detecting accuracy of the black box reaches the expected requirement and meet real needs.
