Since 1985 a number of Russian satellites, in the co-called
GEOIK series, carried radar altimeters. Previously classified data from
of these satellites, from mid 1985 to 1995, is being transferred to the
World Data Centers. Ten years of altimeters data from the Russian GEOIK
satellites hase been analyzed to estimate the mean sea surface and gravity
anomalies for World ocean and to compare this data to GEOSAT and ERS data.
These Russian satellites were in near circular orbits at an altitude of
about 1500 km. Most had an inclination of 74 degrees, but some had an inclination
of 83 degrees. The altimeters operated at a frequency of 9.5 Ghz with instrument
error of from 0.5 to 0.8 m for the various spacecraft. The mean sea surface
and gravity anomalies are discussed. Project of the set up an integrated
satellite altimetry data base in Geophysical Center RAS, telecommunication
access to this Russian altimetry data and the future prospects are discussed
also.
