我们已经安装了数值积分轨道的主要土星卫星的天文观测的时间间隔1966年9月至2003年12月，并与先锋11号，旅行者号和卡西尼号航天器获得的数据。拟合的结果是卫星的新星历和土星系统的修正重力场。我们包括精度评估的星历和重力参数。
We have fitted numerically integrated orbits for the major Saturnian satellites to a large set of astrometric observations over the time interval 1966 September to 2003 December and to data obtained with the Pioneer 11, Voyager, and Cassini spacecraft. The results of the fit are new ephemerides for the satellites and a revised gravity field for the Saturnian system. We include an accuracy assessment for the ephemerides and the gravity parameters.
