Abstract : The computer program for the refinement of the orbital parameters of a satellite, PROP, has been used to determine the orbit of Transit 1B (1960 gamma 2) for epochs spread throughout the life of the satellite. About 200 observations were used from 45 different stations to obtain orbital parameters at each epoch. Most of the observations were visual, but some photographic and radar observations were also used. The orbital parameter of chief interest for geophysical studies is the inclination, and accurate values of this parameter were obtained, the s.d. varying between 0.0004 deg for the best orbits and 0.007 deg for the worst.
