AB: The International GNSS Service (IGS) is a voluntary collaboration of more than 200 worldwide agencies that pool resources to generate precise GPS and GLONASS products. The foundation of the IGS is a global network of 385 permanent, continuous, geodetic-quality stations independently operated by about 100 agencies. The IGS Central Bureau develops minimum functional requirements and operational standards that enable the individual stations' data to be used coherently in global analyses, but the IGS remains vendor neutral, leaving procurement decisions and implementation details to the individual agencies. The IGS network is hence quite heterogeneous in instrumentation, station management strategies, and culture; these diversities bring both strengths and challenges in coordination. This presentation will detail the IGS's approaches, successes, and opportunities for improvement in coordinating and monitoring the collaborative network.
