The International GPS Service - What´s Next? 10th Anniversary Assembly Charts Future Directions

摘要

The International GPS Service (IGS) celebrates ten years of successful scientific service in 2004. Since 1994, the IGS produces GPS data and products at the highest level of precision and accuracy available anywhere. A key objective of the IGS is to provide users anywhere in the world access to highest level GNSS data, products and resources, through an “open data policy”. This is naturally dependent upon the availability and performance of the various satellite systems. From modest beginnings, the IGS now consists of over 200 actively contributing organisations in more than 80 countries and a global network of 350+ stations with numerous associated regional networks.
