AB: The strategies of the IGS* to optimize the future use of multiple integrated GNSS - GPS and its modernization, the new Galileo, and GLONASS will be discussed. This is particularly important towards sustaining and evolving the precise reference frame maintained by the International Earth Rotation and Reference System's (IERS) International Terrestrial Reference Frame (ITRF). Since 1994, the IGS produces GPS data and products at the highest level of precision and accuracy available anywhere. IGS provides GPS orbits (3-5 cm wrms), sub-cm 3-D station positioning and velocities, and station and satellite clocks (sub-nanosecond) for users worldwide. A similar suite of data and products is available for GLONASS, demonstrating the ability of the IGS to incorporate observations from other GNSSs. IGS affirms interest to engage in the development and applications of the Galileo system and other GNSS. The authors will discuss IGS commitment to supporting the precise global reference frame and its densification through the GNSS techniques. A key objective of the IGS is to provide users anywhere in the world access to GNSS data, products and resources as a "global utility". This is naturally dependent upon the availability and performance of the various satellite systems. IGS currently consists of over 200 actively contributing organizations in more than 80 countries and a global network of 350+ stations. (*IGS is recently renamed as the International GNSS Service, formerly the International GPS Service).
