Cassini orbit determination from launch to the first Venus flyby

摘要

This paper describes the Cassini orbit determination effort from injection through the first Venus flyby. ^Emphasis is placed on orbit determination modeling and the resulting orbit solutions. ^Key solutions supporting trajectory correction maneuver designs are presented and compared against the Venus flyby trajectory reconstruction. ^The trajectory reconstruction is discussed in detail, as it is currently the best representation available of the Cassini flight path. ^(Author)
