A review of currently available IGS network summaries

All components of the International GPS Service (IGS) community have cause to seek metrics, reports, or summaries of the IGS network. Station personnel may wish to monitor the performance of their own stations, users need to select subnetworks of stations appropriate to a particular study, and analysts must understand station configurations to assure high quality results. With its role in day-to-day management and coordination of the IGS, the Central Bureau devises and maintains information appropriate to these needs on its information system, and also refers users to useful summaries maintained at IGS Data Centers and Analysis Centers. This paper reviews the content and possible usage of several network summaries that are located at or useful to the Central Bureau, with the intent of ensuring that the community has ready access to information that enables both assessment and improvement of network performance.
