IGS Product Availability

IGS Product Availability

Three types of GPS ephemeris, clock and earth orientation solutions are computed.

Final: The final combinations are available at 12 days latency.
Rapid: The Rapid product is available with approximately 17 hours latency.
UltraRapid: The UltraRapid combinations are released four times each day (at 0300, 0900, 1500, and 2100 UT) and contain 48 hours worth of orbits; the first half computed from observations and the second half predicted orbit. The files are named according to the midpoint time in the file: 00, 06, 12, and 18 UT.

Please DO NOT write scripts to repeatedly check this area for new ephemeris files!

For best reliability, you should use IGS Data Centers, automatically failing over to another one in case one is not available.

Full details, including redundant access availability at IGS Global Data Centers, are available in the IGS Product table.

This table indicates the most recent IGS ephemeris found by this server for recent days:
