Atmospheric rotation produces a change in orbital inclination which decreases under the effect of zonal winds. Inclination values obtained for Cosmos 482 are analyzed to determine the atmospheric rotation rate of the zonal wind (East-West) at a height near 235 km. Orbital parameters of Cosmos 482 at 55 epochs from August 1975 to October 1977 were determined by the PROP 6 program, and calculations reveal a diurnal and seasonal dependence. The atmospheric rotation rate has a low average value of 0.9 in summer and a high evening value of 1.4 during the winter months. Resultant wind velocities vary between 48 m/s east to west and 193 m/s west to east, with an average of 48 m/s west to east.
