Abstract
A method for estimating the geographical latitude, longitude and elevation of a mobile electronic telecommunication device (TD) is provided. The method draws random information over a given time period from multiple responders. A triangulation and signal quality analysis is performed to determine the possible location of the TD. Using the statistical information and its analysis the location (x, y and z coordinates) as well as the velocity and acceleration of the device is estimated. The present invention provides extremely accurate location information.
