Surely this depends on whether the spacecraft has earth synchronous rotation or not. A three axis stabilized spacecraft pointing its instruments at various stellar objects does not rotate. If the center of mass of such a spacecraft is in a circular orbit, then points distributed about this point will be in various elliptical orbits which maintain a constant separation. If we assume a polar or equatorial orbit, wouldn't the perturbations be negligible ? -- Made in New Zealand --> Brent Callaghan AT&T Information Systems, Lincroft, NJ {ihnp4|mtuxo|pegasus}!phoenix!brent (201) 576-3475
