A determination of the radio-planetary frame tie from comparison of Earth orientation parameters [PDF]
, 1992 The orientation of the reference frame of radio source catalogs relative to that of planetary ephemerides, or 'frame tie,' can be a major systematic error source for interplanetary spacecraft orbit determination.
