1.前言因为奥米伽信号是极好的,所以尽管它们只覆盖很小的频率范围(10.2至13.6kHz),但是就是这个小频带对在格陵兰和南极洲发现的厚冰河冰特性的变化是特别敏感的。今天澳大利亚奥米伽导航系统把最强的信号放入南极洲的北海岸,北维多利亚地区,正如我们要显 1. Introduction Because Omega signals are excellent, even though they cover only a small range of frequencies (10.2 to 13.6 kHz), it is this small band that is particularly sensitive to changes in the ice characteristics of thick glaciers found in Greenland and Antarctica Sensitive. Today Australia Omega navigation system put the strongest signal into the northern coast of Antarctica, North Victoria, as we have to show significant
