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
