ASTRO-G 精密軌道決定用レーザリフレクタの設計2 配列と光学応答

摘要

Highly precise orbit information is required for the future space-VLBI satellite, ASTRO-G. Laser retroreflectors forsatellite laser ranging observations are considered effective for cm-precision measurement, in addition to GPS receivers.Based upon the optical response of single retroreflectors, the optical responses of whole retroreflector array arenumerically simulated for the currently proposed two types of arrangement. Laser ranging precision are also simulatedfor the possible angle of incidence toward the arrays.
