DTIC AD0471329: THE EFFECT OF TRANSFER INJECTION ERRORS UPON THE ACCURACY OF HIGH CIRCULAR ORBITS

First-order relationships between the position and velocity errors at start and end of a Hohmann transfer are derived in a two-dimensional analysis. The results are then used to evaluate the effects of uncorrected first injection errors upon the mean radius and eccentricity of the final (nominally circular) orbit, assuming perfect application of the final impulsive velocity. Finally the mean radius and eccentricity errors are expressed in terms of post-orbital velocities required for nulling, such as would be required in station-keeping communication satellite systems.
