TL;DR: The status and tracking capabilities of the IGS monitoring station network are presented and the multi-GNSS products derived from this resource are discussed and the achieved performance is assessed and related to the current level of space segment and user equipment characterization.

TL;DR: The CDDIS data system and its archive have become increasingly important to many national and international science communities, particularly several of the operational services within the International Association of Geodesy and its observing system.

TL;DR: To facilitate the joint analysis of GNSS observations and satellite laser ranging measurements, laser retroreflector array coordinates consistent with the IGS-specific spacecraft frame conventions are provided in addition to representative antenna offset values for all GNSS constellations.

TL;DR: The organizational aspects of the IDS are addressed, there is now a wide international participation within IDS that should lead to future improvements in DORIS analysis strategies and DORis-derived geodetic products.

TL;DR: The article will give an overview of activities underway within the ILRS, paths forward presently envisioned, and current issues and challenges.
