61 Sequenced heat rejection for body stabilized geosynchronous satellites US203710 1998-12-02 US06073888A 2000-06-13 Walter S. Gelon; John C. Hall; Christian J. Goodman
In one embodiment, a thermal radiative system for an earth orbiting satellite including a plurality of faces intermittently exposed to maximum solar illumination comprises a thermal radiator is mounted on a face for discharging heat from a thermal load to deep space. A heat conductor extends between the thermal load and the thermal radiator. Thermal switches are operable for connecting the thermal load to the thermal radiator for cooling when the temperature of the thermal load is above a predetermined level and for disconnecting the thermal load from the thermal radiator when the temperature of the thermal load falls below the predetermined level. A shield including phase change management (PCM) material is thermally connected to the thermal load for drawing heat away therefrom. In another embodiment, first and second thermal radiators are mounted on first and second faces, respectively, of the satellite for discharging heat from the thermal load and the thermal load is sequentially connected to the first and second thermal radiators to achieve optimum discharge of heat from the thermal load. To this end, the thermal load is thermally connected to the first radiator so long as the first radiator is exothermic and thermally disconnected from the first radiator when the first radiator becomes endothermic and is thermally connected to the second radiator so long as the second radiator is exothermic and thermally disconnected from the second radiator when the second radiator becomes endothermic.

63 Practical orbit raising system and method for geosynchronous satellites US09328911 1999-06-09 US07113851B1 2006-09-26 Walter Gelon; Ahmed Kamel; Darren Stratemeier; Sun Hur-Diaz
A practical orbit raising method and system wherein a satellite quickly escapes the Van Allen radiation belts and payload mass and mission life are maximized. A satellite is launched that contains high thrust chemical propulsion thrusters, high specific impulse electric propulsion thrusters and a solar array. The satellite quickly escapes the Van Allen radiation belts by firing the high thrust chemical propulsion thrusters at apogees of intermediate orbits, starting from the transfer orbit initiated by a launch vehicle, to successively raise the perigees until the perigee clears the Van Allen radiation belts. The payload mass and mission life are maximized by firing high specific impulse electric propulsion thrusters to raise the satellite to near synchronous orbit, while steering the thrust vector and solar array to maintain the sun's illumination on the solar array. The chemical and/or electric propulsion thrusters are then fired to achieve geosynchronous orbit.

65 Elliptical satellite system which emulates the characteristics of geosynchronous satellites US09892132 2001-06-25 US06678519B2 2004-01-13 David Castiel; John Draim; Kenneth F. Manning
An elliptical satellite communication system including a constellation of satellites which orbit the earth at a height less than that necessary for geosynchronous orbits but which simulate the characteristics of geosynchronous orbits. The satellites' velocity near the apogee portion of their orbit approximates the rotational velocity of the earth, and during that period appear to hover over the earth. The ground stations on the earth always communicate with a satellite at or near its apogee, and hence that satellite appears to the ground station to hover over the earth. During the times when the satellite is outside the apogee portion, its communication is shut off to prevent any possibility of interfering with geosynchronous satellites and its power supply is used to charge a battery on the satellite. Thus, the power supply of the system can be reduced by an amount equivalent to the percentage of time the satellite is not used.
66 Elliptical satellite system which emulates the characteristics of geosynchronous satellites US09056051 1998-04-06 US06263188B1 2001-07-17 David Castiel; John Draim; Kenneth F. Manning
An elliptical satellite system which carries out communication. The satellite orbits a height above the earth less than that necessary for geosynchronous orbits. When the satellite is near the apogee portion of its orbit, its velocity approximates the rotational velocity of the earth, and during that period it appears to hover over the earth. Each ground station on the earth always communicates a satellite within a predetermined position of its apogee, and hence that satellite appears to the ground station to hover over the earth. The satellite hence does not communicate with any earth station when it is outside of that apogee portion. During the times when the satellite is outside the apogee portion, its communication is therefore shut off to prevent any possibility of interfering with geosynchronous satellites. During this time, the power supply on the satellite is also used to charge a battery on the satellite. This enables the power supply to be made smaller by an amount equivalent to the duty cycle of the satellite: during the time which it is on.
67 System and method for the acquisition of a non-geosynchronous satellite signal US949989 1997-10-14 US5929808A 1999-07-27 Amer A. Hassan; Sami M. Hinedi; James R. Miller
An antenna having multiple antenna elements that are selectively activated performs an initial acquisition of a satellite signal by activating only a few of the antenna elements. This results in a broad beam width and increases the likelihood of detecting the signal from the satellite. When the satellite signal is initially detected, the system increases the number of active elements to narrow the beam width. The system incrementally increases the number of active antenna elements until the detected signal from the satellite exceeds a predetermined threshold. At that point, the location of the satellite may be precisely determined and all antenna elements activated to lock onto the satellite signal. If the antenna loses acquisition of the satellite signal, the reverse process may be implemented whereby some elements are selectively deactivated to broaden the beam width of the antenna in an effort to reacquire the satellite signal. When the satellite signal is reacquired, the antenna elements are incrementally reactivated until all antenna elements are active.
68 System for controlling the direction of the momentum vector of a geosynchronous satellite US118847 1980-02-05 US4325124A 1982-04-13 Udo Renner
A system for compensating the disturbance torques applied to a satellite, which eliminates the requirement for a thruster control loop. The disturbance torque itself is used as the compensating torque in order to super-impose to the incidental misalignment of the solar panel arrays an artificial misalignment that can cause the momentum vector to be adjusted to the desired direction in order to restore the correct attitude of the satellite. The direction of the momentum vector is controlled in orbit only by solar sailing, that is by organizing at prescribed times suitable manoeuvres of one of the solar panels in order to adjust the solar panel array configuration when the roll angle of the satellite exceeds a determined threshold value.
