Hi, first question to StackOverflow, please be gentle.
- I am trying to find the equation (and then the algorithm for) the center point of three different points on a 2D cartesian plane, given a certain magnitude or "signal strength". These signal strengths are all on a scale relative to each other, but shouldn't necessary be conflated with "radius" of a circle.
Wikipedia entry on trilateration: http://en.wikipedia.org/wiki/Trilateration
I've also checked out this thread, but it's a little different than what I need http://stackoverflow.com/questions/2813615/trilateration-using-3-latitude-and-longitude-points-and-3-distances
A general equation is nice, but I'll provide some sample data points here for testing:
P1: X,Y = 4153, 4550 // Magnitude or Signal strength = 143
P2: X,Y = 4357, 4261 // Magnitude or Signal strength = 140
P3: X,Y = 4223, 4365 // Magnitude or Signal strength = 139
My general sense is that these points need to be translated to be on the same scale (the signal strengths and the points), but I could be wrong.
Thoughts? TIA
