Final products
The Final products are the results of offline analysis on the orbits and the clock of the GPS and QZSS satellites , position of the monitoring station and the earth rotation parameter(ERP). The final products are to be released approximately 3 to 7 days later according to the kind of product. Please note that the difference may increase during the events such as an attitude maneuvering.
They are lists data below.
(1)Daily final orbit
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.
(2)Daily final clock
the clock for satellites and monitoring station. The data format is Clock Rinex 3.02.
(3)Daily final ERP
Information about earth rotation parameter. The data format is IGS ERP format(version 2)
(4)Daily monitoring station position
The data format is SINEX 2.02
(5)Weekly monitoring station position
The data format is SINEX 2.02
