Abstract
Results are presented for the orbit determination of the three satellites of Kaguya. Doppler data fit for the main satellite is typically at a level of 0.5 mm/s, and that for the subsatellites is typically less than 0.5 mm/s. Orbit accuracy for the main satellite from altimeter crossovers gives a total orbit accuracy of 50 m. Orbit overlaps confirm this total accuracy, and show a radial accuracy of generally less than 1 m. For the subsatellites Rstar and Vstar, accuracy is restricted due to sparse data coverage, but the inclusion of high-precision differential VLBI data improves the consistency of the orbits greatly, to a level of ten meter in a three-dimensional sense.
