ORBITAL POSITION ESTIMATION METHOD, ORBITAL POSITION ESTIMATION DEVICE AND ORBITAL POSITION ESTIMATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an on-board orbital estimation method that solves troublesomeness in operation while preventing deterioration of directional stability of a movable body.SOLUTION: An estimation method for estimating the orbital position of a movable body, includes the step of: acquiring positional information on the movable body to remove a non-linear term from the positional information; time-propagating positional information from which the non-linear term is removed; and obtaining the estimation value of orbital position of the movable body by adding the non-linear term to the time-propagated positional information.
