java.lang.Object

com.irurueta.navigation.indoor.position.SequentialRobustMixedPositionEstimator<com.irurueta.geometry.Point2D>

com.irurueta.navigation.indoor.position.SequentialRobustMixedPositionEstimator2D

public class SequentialRobustMixedPositionEstimator2D
extends SequentialRobustMixedPositionEstimator<com.irurueta.geometry.Point2D>

Robustly estimates 2D position, using RSSI readings first to obtain an initial coarse position estimation, and then ranging readings to refine such estimation.

This implementation is like SequentialRobustRangingAndRssiPositionEstimator but allows mixing different kinds of readings (ranging, RSSI or ranging+RSSI).
