The rotation is accomplished as a 'right hand rule' rotation. The base frame is the internal J2000 frame, also referred to as the Earth Mean Equator and Equinox of 2000 (EME2000) frame or the International Celestial Reference Frame (ICRF). This is called the J Frame in some project documentation. The target frame is the 'Spacecraft Coordinate System (S-frame),' the principal reference frame associated with the DS1 spacecraft. The MICAS 'primary aperture' is defined to be coincident with the spacecraft S-frame. DS1 spacecraft and instrument reference frames are described in detail in two places: 1) 'DS1 Coordinate Systems, Vectors and Phasing Definitions;' Version 2.0; Douglas W. Caldwell; 19 September 1997. 2) The DS1 SPICE Frame Specifications kernel (FK), which is a component of the DS1 SPICE archive collection. This file is named ds1_vxx.tf, where xx is the current version number. As the DS1 SPICE archive has not yet been finalized, this version number may change: it is presently (MARCH 2004) ds1_v70.tf. The DS1 quaternion, or rotation matrix (ROTMAT) made from it, will rotate a vector given in the base reference frame to the equivalent vector in the target reference frame: [S-frame] = [ROTMAT] x [J2000] 3x1 3x3 3x1 A discussion on the specification and uses of quaternions, including transformations of a quaternion into a rotation matrix, may be obtained from the NAIF Node of the Planetary Data System: 'A Brief Discussion of Quaternions as Used in Space Remote Sensing'; January 25, 2004, C. Acton (editor), NAIF Document No. ??? This same material may also be available in the current PDS Standards Reference, under a Quaternions heading.
