| titleOfInvention | Real-time transfer alignment method and device for airborne distributed POS |
| abstract | The embodiment of the invention provides a method and a device for real-time transfer alignment of airborne distributed POS (point of sale), wherein a transfer alignment mathematical model and an error model under a large misalignment angle condition are established, KF (Kalman Filter) and UKF (unscented Kalman Filter) are used for respectively carrying out time updating and measurement updating of a linear state variable and a nonlinear state variable, then a linear state variable estimation value and a nonlinear state variable estimation value are used for correcting the speed, the position and the posture of a subsystem, the position error and the error existing when the linear state variable estimation value is used as a parameter during nonlinear filtering are considered, and the nonlinear state variable estimation value is used as a parameter during linear filtering, and the compensation is carried out when a nonlinear state variable one-step prediction covariance matrix and a linear state variable one-step prediction covariance matrix are respectively calculated, so that the precision of transfer alignment is improved. |
