Utility to calculate long and short path to a location
Gcb computes long and short path given the latitude and longitude (degrees and minutes). You must input the lat/long of the two stations. The output will then be relative from station1 to station2.
Gcb is used by hamradio operators as a tool for pointing the antenna in the right direction, either by using the short (daylight) propagation path or using the long path, which is almost always via the dark side of the earth.
Gcb believes the earth to be a perfect circle, which means there will be small calculation errors.
