Research on integrated navigation using UKF order filtering.

Kalman filtering requires the calculation of Jacobian matrix in integrated navigation, when the model is too complex or Jacobian matrix cannot be obtained it is difficult to deal with the issue, the UKF sequential filtering method was proposed. To solve these problems, the method used the UKF filter, the GPS information and navigation information, successively using new information to make correction estimates. The method was used in ship navigation, and the simulation results proved the effectiveness of the algorithm. [ABSTRACT FROM AUTHOR]
