Introduction, to a coordinate system at a given time. In general, spacecraft navigation refers only to the determination of orbit parameters. In general, the navigation relying on only the onboard measuring and computing devices rather than ground support is referred to as spacecraft autonomous navigation, while

Point Estimation Theory,(also called estimation rules), defining the corresponding rules of inference, can be classified into point and interval estimators. A point estimator gives an approximate value of unknown parameters, whereas an interval estimator calculates an interval that covers the unknown parameters with a high

Dynamic Models and Environment Models,established. This chapter first addresses orbital perturbation model, establishes orbit dynamic equations, and then elaborates on four typical parametric forms for attitude description, the conversion relations between attitude parameters, and the attitude kinematics model corresponding to each para

Inertial Autonomous Navigation Technology,) are presented at first. For high accurate application, in order to reduce the influence of output noise on the calculation accuracy of the system and make full use of the output information, the outputs of gyroscope and accelerometer are all increments, namely the angle increment output by gyrosco
