Founderian Coordinates Calculator

"To ALWAYS know the proper direction to genuflect. BEER!! be praised!"

Input your current location in Lat1/Long1.
Location of KBS Prime is already in Lat2/Long2.
Find your current location here.
Lat 1
Long 1
KBS Prime Lat 2
KBS Prime Long 2

Distance Units: Earth model:

Course 1-2 (deg)
Course 2-1 (deg)
Shortest distance
Values of "Course 1-2" and "Shortest Distance" form your Founderian Coordinates.
The One


1. Enter your Latitude and Longitude in "Lat 1" and "Long 1". Enter Lat/Long in the form DD.dddddd (do not use a negative sign for West longitudes or South latitudes) or DD:MM.mmm or DD:MM:SS.ss, where colons separate degrees, minutes and seconds. Different styles may be used for each Lat/Long entry. Entry of decimal places is not required for the calculator to operate, but all four lat/long boxes must have something entered (even a single zero).

2. Select desired distance units and earth model, and click on the "COMPUTE" box.

3. If the calculation does not complete click the "RESET KBS LAT/LONG" button, re-enter your lat/long, then click "COMPUTE" again.

4. For calculating coordinates for kBS click the "RESET kBS LAT/LONG" button, re-enter your lat/long, then click "COMPUTE".

1. Conversion factors used (exact figures, by international definition): International Nautical Mile = 1852m; Statute Mile = 5280ft; 2.54cm = 1 inch = 1/12 ft.
2. Above about 89 degrees latitude, and between near-antipodal (opposite) points, courses may not be accurate.
