public class MSACRobustRssiPositionEstimator3D
extends RobustRssiPositionEstimator3D

Robustly estimates 3D position using located radio sources and their RSSI readings at unknown locations and using MSAC algorithm to discard outliers. This kind of estimator can be used to robustly determine the 3D position of a given device by getting readings at an unknown location of different radio sources whose 3D locations are known.

Sets threshold to determine whether samples are inliers or not when testing possible solutions. The threshold refers to the amount of error on distance between estimated position and distances provided for each sample.

Parameters:

threshold - threshold to determine whether samples are inliers or not.

Throws:

IllegalArgumentException - if provided value is equal or less than zero.

com.irurueta.navigation.LockedException - if this solver is locked.
