Abstract

We investigated basic characteristics of the telescope for In-situ Lunar Orientation Measurement (ILOM), such as the centroid accuracy and the effects of temperature change, tilt and ground vibrations, by laboratory experiments using a Bread Board Model and by simulations. We have a prospect to observe the lunar rotation on the lunar surface with the accuracy of 1 milliarcsecond. We will make test observations on the ground in order to evaluate overall characteristics with the target accuracy of better than 0.1 arcseconds.
