The Governments of the United States of America and Japan convened a plenary meeting in Tokyo, Japan on January 13, 2011, to review and discuss cooperation in the civil use of the Global Positioning System (GPS) and GPS augmentations, including Japan’s Multi-functional Transport Satellite (MTSAT) Satellite-based Augmentation System (MSAS) and Quasi-Zenith Satellite Systems (QZSS). The GPS consultations are held regularly pursuant to the “Joint Statement on Cooperation in the Use of the Global Positioning System” signed by the heads of the two Governments on September 22, 1998.

During the meeting, U.S. representatives described the status of Wide Area Augmentation System (WAAS) and GPS modernization and the United States’ international GPS cooperation with third parties. Representatives of the Government of Japan reported on the status of the Multi-functional Transport Satellite Satellite-based Augmentation System and Quasi-Zenith Satellite Systems programs and on Japan’s international Global Navigation Satellite System (GNSS) – related cooperation activities. Both Governments reaffirmed the importance of providing open access to basic space-based positioning, navigation and timing (PNT) services for peaceful purposes, free of direct user fees. Both Governments reiterated that GPS and its augmentations have become indispensable for modern life in the U.S., Japan and the world, providing essential services and increased efficiencies in a broad range of applications, such as aviation and maritime safety-of-life, geodetic surveying, car and personal navigation, mobile telephone timing, international financial transactions and electric power transmission.

Representatives of both Governments reviewed the ongoing work of the Global Positioning System/Quasi-Zenith Satellite System Technical Working Group, which was established to foster close cooperation during the development of Quasi-Zenith Satellite System. The Technical Working Group reaffirmed that both systems are designed to be compatible and highly interoperable. Both Governments noted with satisfaction that the Japan Aerospace Exploration Agency and the U.S. National Oceanic and Atmospheric Administration (NOAA) have commenced operations of a Quasi-Zenith Satellite System Monitoring Station on NOAA property in Guam. A similar effort between the Japan Aerospace Exploration Agency and the U.S. National Aeronautics and Space Administration (NASA) to establish both a Quasi-Zenith Satellite System monitoring station and a Two-Way Satellite Time and Frequency Transfer station at a NASA facility in Hawaii, in support of Japan’s National Institute of Information and Communications Technology and the U.S. Naval Observatory, is expected to be completed shortly. Both Governments intend to continue cooperation in protecting spectrum used for GNSS and also reaffirmed the importance of pursuing the interoperability and compatibility of all current and planned global navigation satellite systems with Global Positioning and Quasi-Zenith Satellite Systems.

This 8th Plenary meeting strengthened cooperative relations between the United States and Japan. Both Governments acknowledged the important future contribution of Quasi-Zenith Satellite System to the space-based positioning, navigation and timing services of Japan. They affirmed that continued close cooperation in the area of navigation satellite system will contribute to the peaceful development of the Asia-Pacific region and promote global economic growth. In that regard, both Governments welcomed the 6th meeting of the International Committee on Global Navigation Satellite Systems to be held in Tokyo, September 5-9, 2011, and the 3rd Asia Oceania Regional Workshop on Global Navigation Satellite Systems to be held in Japan’s fiscal year 2011.
