Study for Appling the PPT to Perform Small Satellite Orbit Transfer Mission

To the CAST968 small satellite plate,based on the HY-1 small satellite,the requirement of its orbit transfer mission is indicated.As contrasted with the monopropellant hydrazine thruster which was used in the HY-1,the PPT applied characters are referred to.According to shape and structural parameters of the HY-1,the number and the work scheme of orbit transfer PPT are designed roughly.The PPT orbit transfer methods are demonstrated and analyzed according to the PPT state-of-the-art and its propulsive ability,and the correlative orbit transfer parameters are calculated.This research indicates that the PPT can be used for the limited energy orbit transfer mission of the small satellite,and it has the evident predominance,compared with the traditional chemical propulsion system.
