Class INSLooselyCoupledKalmanInitializer

java.lang.Object

com.irurueta.navigation.inertial.INSLooselyCoupledKalmanInitializer

public class INSLooselyCoupledKalmanInitializer
extends Object

Initializes the loosely coupled INS/GNSS Kalman filter error covariance matrix. This implementation is based on the equations defined in "Principles of GNSS, Inertial, and Multisensor Integrated Navigation Systems, Second Edition" and on the companion software available at: https://github.com/ymjdz/MATLAB-Codes/blob/master/Initialize_LC_P_matrix.m

Method Details

initialize

public static void initialize(INSLooselyCoupledKalmanInitializerConfig config,
 com.irurueta.algebra.Matrix result)

Initializes INS/GNS loosely coupled Kalman filter error covariance matrix.

Parameters:

config - Kalman filter configuration.

result - instance where resulting initialized error covariance matrix will be stored. Matrix must be 15x15, otherwise it will be resized.
