SOPAC archives RINEX observation (rinex/obs), navigation (nav), and meteorological (met)
files from arrays around the world.
In addition, SOPAC provides several GPS satellite orbit files and associated products.
The "products" selection includes (note: YYYY=year, DDD=day-of-year, WWWW=gps weeek, D=day-of-week,
Y=year in decade, HH=hour-of-day):
gfiles: orbit files that can only be used in GAMIT GPS data processing.
combinations: weekly GLOBK processing results.
Weekly orbits, repeatabilities, positions and more, in GAMIT/GLOBK format.
hfiles: the official GAMIT solution exchange file. ASCII file, with coordinates,orbits
and the full variance-covariance matrix. Can be used as pseudo-observations into the GLOBK package.
sp3 precise ephemeris orbits in sp3 format (e.g., sioWWWWD.sp3.Z)
earth orientation files (e.g., sioWWWWD.erp.Z)
sinex files (e.g., sioWWWWD.snx.Z
analysis summary files (e.g., sioWWWW7.sum.Z)
clock files derived by a variety of analysis centers
Orbits are available from IGS and all IGS analysis centers (sio, jpl, cod, ngs, emr, usn, cod and gfz).
Filenaming conventions use the following, where 'xx' represents the first two letters of the IGS analysis
xxo: final orbits, available within 10 days after the end of the UT day (e.g., sioWWWWD.sp3.Z)
xxr: rapid orbits, available after 17 hours (e.g., sirWWWWD.sp3.Z)
xxu: ultra-rapid orbits, provided every three hours (e.g., siuWWWD_HH.sp3.Z)
Rinex files on the SOPAC archive have been converted to the Hatanaka format.
