Abstract:

A previous note by Brady and Crombie NBS TN 209 describes methods and a program for calculating and plotting sunrise and sunset times at specified heights and distances along a great circle path determined by the locations of the end points. The program also plots the distribution of darkness or daylight along the path versus time. This program has been modified to remove some restrictions on the use of the earlier program, and to provide the option of calculating the short or long great circle path. In addition, transmitter, receiver, and solar bearings are also calculated and plotted. Some interesting characteristics of the short and long paths from Rugby, England, to Byrd Station, Antarctica, are shown. Author
