SPICE Data
These data sets include SPICE data, which contains time-series details of the position and pointing of the spacecraft, and the position and rotation state of the planets/small bodies. It also includes exact definitions of the spacecraft equipment and instruments, to include how they are oriented on the spacecraft. The complete SPICE information provides deterministic information to compute relative and inertial positions, pointing and angles of objects in space.
