Abstract: According to one embodiment of the invention, a stationkeeping method for a geostationary satellite includes determining a gravitational force of the sun on the satellite at a beginning of a stationkeeping operation and a gravitational force of the moon on the satellite at the beginning of the stationkeeping operation. An initial inclination vector of the satellite is determined at the beginning of the stationkeeping operation that accounts for a first set of one or more perturbations affecting the orbit of the satellite. A maneuver strategy is determined to correct for a second set of one or more perturbations affecting the orbit of the satellite without accounting for the first set of one or more perturbations affecting the orbit of the satellite. Finally, a maneuver is performed on the satellite according to the maneuver strategy.

Abstract: The invention comprises an adjustable frame for a the concave mold of a pre formed two piece mold having a convex mold and a concave mold adapted to be closed to mold a product. The adjustable frame has surrounding sides and a bottom with an open top to removably receive and support the preformed concave mold of the two piece mold, said surrounding sides and bottom with the surrounding sides have a plurality of elongated pins extending inward toward one another, and with the bottom having a plurality of pins extending upward to thereby support the surrounding sides and bottom of a concave mold, with the pins being adjustable along their length inward toward one another and upward to enable the same frame to support different concave molds of different shapes and sizes therein in connection with the convex molds to form products of different sizes and shapes.
