A Simple Closed-Form Solution of a Position-Fixing Problem.

Abstract

A closed-form solution was obtained for the problem of finding an object's location given ranges to four stations of known location. The method is simple, involving only simple algebra such as addition and multiplication and the evaluation of a few trigometric functions. Only three stations are required for the solution if some other a priori information is available such as height above the earth or the azimuth. (Author)
