The Rapid products are the results of offline analysis on the orbits and the clock of the GPS and QZSS satellites and the earth rotation parameter(ERP). The rapid products are to be released approximately 1 day later. Please note that the difference may increase during the events such as an attitude maneuvering. They are lists data below.
the orbits and the clock for each satellite at each given time. Consult the sp3c format for more information. In the products, "Time System" (Line13 Columns10-12) indicates "QZS", the time system that is identical to the GPST with a difference of a few nanoseconds. Besides please note that the navigation messages are compliant with GPST.
