(32S II) Position, Distance & Bearing Calculations

[SlideRule]

An extract from Position, Distance & Bearing Calculations, Whitham D. Reeve (©2014 W. Reeve)

Two frequent calculations required in radio propagation work are distance and bearing between two radio terminals. Distance and bearing may be taken from topographical maps for quick analyses but great circle calculations are needed for more accurate work and are described here …
If more than a few sites are being evaluated, it can be more productive to use a programmable calculator or spreadsheet program to find distance and bearings. The program listing in the appendix was written for this purpose on the Hewlett-Packard HP-32S II calculator, but it can be adapted for other scientific calculators that use Reverse Polish Notation (RPN) with minor changes (if any). The program can accept the coordinates in either dd+mm+ss (for example, 66 52' 31.5") or dd.dddd (for example, 66.5407) by setting the input mode, and it automatically resolves any ambiguity.

Excellent documentation w equations, tables, figures, examples etc., …

BEST!
