Trilateration
Trilateration system using 3 latitude and longitude points, and 3 radius distances in PHP, C#, Java and Javascript
Where can Trilateration and Triangulation be used in general?
- Get the location of a device that sends signals to an antenna (GPS).
- Get the location of any device connected to a Wi-Fi network.
- Get the epicenter of seismic events (Earthquakes).
And several other uses, with this library so simple you can perform the calculation, of course, this library does not know the parameters and these have to apply to you.
Class parameters and functions
Point Class:
new Point(Latitude,Longitude,RadiusDistanceInKilometers);Trilateration Class:

Compute(Point1,Point2,Point3);PHP Version Example
<?php
require("Point.php");
require("Trilateration.php");
$p1=new Point(-19.6685,-69.1942,84);
$p2=new Point(-20.2705,-70.1311,114);
$p3=new Point(-20.5656,-70.1807,120);
$a=new Trilateration();
$b=$a->Compute($p1,$p2,$p3);
echo "LatLon: ".$b[0].", ".$b[1];
?>Result
LatLon: -20.548034139289, -69.266174618331
