ORBITAL TRANSFER METHOD OF A SPACECRAFT USING A CONTINUOUS OR QUASI-CONTINUOUS THRUST AND ON-BOARD PILOTING SYSTEM FOR IMPLEMENTING SUCH A METHOD

摘要

A method of orbital transfer of a spacecraft using continuous or near-continuous thrust propulsion, the method comprising: • acquiring, at least once in each half-revolution of the spacecraft, measurements of its position and speed; Calculating a thrust control function as a function of said measurements; and Driving said thrust according to said control law; characterized in that said control law is obtained from a Lyapunov control function using orbital, preferably equinoxial, parameters of the spacecraft, averaged over at least one said half-revolution.;An embedded system for piloting a spacecraft to implement such a method and spacecraft equipped with such a steering system.
