World Ground constants

Ground reflection loss calculation on the short wave propagation path.

This App is the first of a collection for HAM Radio short wave operators 1MHz to 30MHz.

They will demonstrate the behavior of the ionosphere on world wide short wave propagation.

World Ground constants are used in ground reflection loss calculation of the short wave propagation.

This App just demonstrate the world wide map of the constants depending on latitude and longitude.

Single point values are calculated for a given latitude and longitude and a scaled color map will show the overview of the world map at 1 degree resolution.

The next App coming soon will display world map of propagation MUF, FOT and number of hops needed from central Europe to anywhere for different solar activities, month and daytime. Hint: Touch the map to get location and value displayed in the upper left corner :-)
