About 1200 observations from 46 observing stations were used to determine the orbit of Cosmos 307 rocket (1969-94B) at 25 epochs spread throughout its nine-month orbital life. The determination was made using the RAE computer program for the refinement of orbital parameters, PROP. The values of orbital inclination obtained, which had standard deviations down to 0.4 sec of arc, were adjusted to account for various perturbations and then used to find the mean rotational speed of the Earth's atmosphere, to give Lambda = 1.06 plus or minus 0.04 rev/day at a mean height of 240 km.
