GNSS satellite orbits and Earth rotation parameters
Orbits of GNSS satellites and Earth rotation parameters based on analysis of GNSS observations from a global network of IGS (International GNSS Service) stations in rapid or ultra-rapid processing mode.
Precise and predicted orbits of GNSS systems. The rapid product contains satellite orbits of GPS NAVSTAR and GLONASS systems with the maximum delay of 48 hours. Ultra-rapid product contains satellite orbits for GPS NAVSTAR and Galileo systems with a maximum delay of 3 hours and with a prediction of 24 hours. Earth rotation parameters are determined once per day.
