The Crustal Dynamics Data Information System (CDDIS) has served as a
global data center for the International GPS Service (IGS) since its
start in June 1992, providing on-line access to data from over 160 sites
on a daily basis. This paper will present information about the GPS and
GLONASS data and products archive at the CDDIS.  General information
about the system and its support of other international space geodesy
services (the ILRS, IVS, and DPE) will also be discussed.
