摘要：

A unified approach utilizing the Kalman-Bucy filtering technique is taken to solve the estimation problem of initial conditions and the smoothing problem in linear dynamic systems. The equivalence between the forward integration method and the backward integration method of the smoothing solution is proved. Complete analytical solutions of filtering and smoothing problems of rectilinear motion of a randomly accelerated spacecraft are derived when the vehicle is tracked by the ranging system at the ground station.
