Omega:Facts, Hopes,and Dreams.

摘要

This paper summarizes a number of ideas that may help to improve the accuracy and reliability of the Omega radio aid to navigation. The study begins with an introduction to the use of coherent signals at various frequencies,and proceeds,using this nomenclature,to show ways in which errors of prediction and propagation can be reduced. It continues with suggestions of how a greater amount of coherent information can be added to the Omega signal format to permit world-wide lane identification,which is needed for improving the efficiency of search and rescue operations,and for other purposes. The conclusion is a study of practical computations for determining latitude and longitude when several time differences are known but when there is no prior knowledge about position. The intent is to provide suggestions for modest improvements in accuracy and a major increase in the reliability and utility of this position-finding system. (Author)
