论文摘要
由于海水介质中的电磁波非常短，因此在水下无法使用GNSS（全球导航卫星系统）定位。在本文中，提出了GNSS定位的LBL（长基线）声学重复器系统。该系统是双曲线的，即基于时间差，并且不需要非常准确的原子钟来同步中继器。
GNSS (Global Navigation Satellite System) positioning is not available underwater due to the very short range of electromagnetic waves in the sea water medium. In this article a LBL (Long Base Line) acoustic repeater system of the GNSS positioning is presented. The system is hyperbolic, i.e., based on time differences and it does not need very accurate atomic clocks to synchronize repeaters.
