3 Terms and definitions

The following terms and definitions defined in GB/T 39267-2020 apply to this document. 3.1 Super fast product Using the latest observation data from the tracking station, the maximum time delay is the orbit, clock difference, earth rotation parameters and tropospheric products released within 3h. Note 1.Generally update every 6h. Note 2.Ultra-fast products start at 0 o'clock, 6 o'clock, 12 o'clock, and 18.00 UTC, respectively. The orbit, clock difference and earth rotation parameter products include 48h product data, Among them, the first 24h is the observation part, and the last 24h is the forecast part; tropospheric products only contain the product data of the 24h observation part. 3.2 Quick product Using the latest observation data from the tracking station, the maximum time delay is the orbit, clock difference, earth rotation parameters and ionospheric products released within 17 hours. Note 1.Generally 1d is updated once. Note 2.Fast products start from UTC0, and the duration is 24h. 3.3 Final product Using the latest observation data from the tracking station, the orbit, clock difference, earth rotation parameters and ionospheric products released with a delay of 10d~17d. Note 1.Generally 7d is updated once. Note 2.The final product starts from UTC0 and has a duration of 24h.
