 note = {ASTROD 1 (Astrodynamical Space Test of Relativity using Optical Devices 1) is to have one spacecraft launched to a solar orbit to range optically with ground stations to meet important scientific goals. The spacecraft is designed to enter the solar orbit from a low earth-orbit and to encounter Venus twice to receive gravity-assistance for achieving shorter periods for making the relativistic Shapiro time delay sooner. In this paper, we first present the orbit design for the 2012 and 2013 launch windows based on our previous method of the 2008 and 2010 orbit design. With a simple noise model, we then present our orbit simulation for the 2012 orbit using 25 parameters of relativistic parameters, celestial-body masses, solar quadrupole parameter, and spacecraft initial position and velocity parameters. We generate five hundred sets of simulated orbit data. From these simulation data, we estimate the uncertainties of the determination of the relativistic parameters gamma and beta to be about 10(exp -7). The uncertainties of other parameters and masses of the celestial bodies including the three big asteroids can be improved considerably., 資料番号: AA0063480015},
