WebIn trilateration, only three points are used. We then have to find the intersection of three spheres. The problem can then be reduced to solving a linear equation followed by a quadratic equation in one variable. The multilateration problem, which allows for more than three points, provides more accurate measurements.

WebJust posted another trilateration, based on the Wikipedia derivation. I believe it is easier to follow it, also it is working in 3D space and returns [ 39.996, 99.996, +/-0.53 ] for your example input, @ravisharma1987 (can be configured to return the middle, then it returns [ 39.996, 99.996, 0 ]). WebGPS positioning is based on trilateration, which is the method of determining position by measuring distances to points at known coordinates. At a minimum, trilateration requires 3 ranges to 3 known points. GPS point positioning, on the other hand, requires 4 “pseudoranges” to 4 satellites.
