Taking a typical transfer alignment model with velocity plus attitude matching as example, three time-delay error compensation methods, namely extrapolating-filtering method, filtering-updating method and modeling method, are systemically analyzed and introduced. To validate and compare their compensation performance, computer simulation is carried out in which a S-shaped flight path was adopted. Simulation results indicate that under this flight condition all three methods could decrease time-delay error of transfer alignment effectively, where filtering-updating method can compensate for the error most thoroughly.
