A study of the OMEGA navigation system and its application to civil maritime use is summarized. Included are evaluations of various OMEGA configurations and techniques for implementing Skywave Corrections (SWC). The material presented is derived from analysis of extensive quantities of actual OMEGA phase data and from contacts within the U.S. maritime community. Four OMEGA configurations--Single Frequency, Composite, Difference Frequency and Differential--are considered in this study. Three conventional SWC implementation schemes are examined. These are the so-called Swanson, Pierce and Trapezoidal models. A simplified SWC technique based on the Swanson model is also evaluated. The above studies and maritime user contacts provide a means to suggest reasonable OMEGA configuration utilization for various environments. These include the high-seas and the coastal/confluence region. Suggestions for future studies based on these findings are presented. |
