Abstract:	The Russian GLONASS system is a global satellite radionavigation system. Although not as well known as the American GPS satellite system, it possesses comparable capabilities for navigation, precise geodetic positioning and time-transfer applications as a stand-alone system or in conjunction with other systems. This paper presents the status of the first international observational campaign for scientific applications of GLONASS called the International GLONASS Experiment (IGEX-98). This campaign is a combined effort of the International Association of Geodesy (IAG), the International GPS Service (IGS), the Institute of Navigation (ION), and the International Earth Rotation Service (IERS). The tracking campaign is scheduled to begin in October 1998 and continue for three months. The global network of tracking sites now includes approximately 30 countries. Scientific goals for the experiment include defining the relationships between reference frames by collocating GLONASS and GPS/IGS receivers, generation of precise GLONASS orbits, collection of satellite laser ranging observations for possible accuracy control and validation of orbits, studying common GLONASS/GPS data processing techniques, receiver equipment and software evaluations, and more precise connections between the GLONASS and GPS reference time scales. These investigations are crucial for the development of some major future space systems, such as the European GNSS project [Pasquay, 1977] and will help resolve some of the interoperability issues associated with satellite navigation systems and augmentation of GPS.
