I do not know what the software is actually doing in the loop which starts in line 1062. Why is
the exception thrown when the loop runs more than 12 times? Because I think that the distance between the give
source and target location is below 20.000 km, and therefor should be correct (or is the max distance in the used
ellipsoid below this limit?)
