3D closed-form triangulation solution

  1. Jan 2, 2007 #1
    I have 3 points in 3D space whose positions are known to me and a third target point, whose position I am trying to find. I can obtain the distance between each of the 3 points and the target point. I can easily get 3 equations to obtain the 3 coordinate variables, but these equations are nonlinear.

    Do you guys know how I could get a simple, closed-form solution for each of the coordinate variables defining the target point? I figured that this would be a fairly standard problem, but I'm having finding anything written about it.

    Thanks in advance.

    This isn't triangulation. Triangulation involves angles. You want something involving distance ... trilateration. See this wiki article on http://en.wikipedia.org/wiki/Trilateration" [Broken].
