Abstract : The problem of using low thrust engines to control the position, period and eccentricity of a satellite's orbit is examined. Equations describing the motion of a satellite in response to constant low level radial and tangential thrusting are developed. A guidance logic for control of the position and period is developed using phase plane techniques. A logic for control of eccentricity is also presented. The problem of orbit determination is also considered. Expressions relating period and position uncertainties as a function of the nominal orbit parameters, tracking errors and tracking time are developed. (Author)
