public class LinearRangingAndRssiPositionEstimator2D
extends LinearRangingAndRssiPositionEstimator<com.irurueta.geometry.Point2D>

Linearly estimates 2D position using located radio sources and their RSSI+ranging readings at unknown locations. These kind of estimators can be used to determine the 2D position of a given device by getting RSSI+ranging readings at an unknown location of different radio sources whose locations are known.
