Abstract

The position of a pilot balloon, which is being followed by two theodolites, can be computed by using all four theodolite angles to make an optimum estimate of the balloon's position and also indicate the probable magnitude of the error in its position. The method described does not fail when the balloon is near or over the base-line, and it is suitable for digital computers.
