About 700 observations from 21 observing stations were used with the RAE computer program PROP to determine the orbit of Explorer 44 rocket 1971-58B, inclination 51.05 degrees, at 17 epochs between June and November 1972, the rocket having passed through exact 15th-order resonance on 20 September 1972. On three of the four runs using Hewitt-camera observations, the standard deviation in inclination was near 0.0001 degrees. The 17 values of orbtial inclination obtained together with 17 US Navy values, after the removal of significant perturbations, were fitted by a least-squares theoretical curve using the RAE computer program THROE.
