    摘要: 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.

    摘要: A spacecraft battery system arranges battery cells in two planes with a common mounting plate between them allowing for a more compact arrangement so the battery assembly can be removed from a limited mounting area resource of the spacecraft such as the north/south faces and placed remotely. Accordingly, a first battery assembly comprised of a plurality of battery cells in electrical continuity are mounted on and spread in a single plane over a first mounting surface of a planar mounting panel and a similarly constructed second battery assembly is mounted on and spread in a single plane over a second, opposed, mounting surface of that same planar mounting panel, the plane of the second battery assembly being spaced from the plane of the first battery assembly. The system includes a plurality of heat pipes embedded in the planar mounting panel and thermally connected with each of the battery cells for distributing heat uniformly across the planar mounting panel. The system also desirably includes a thermal radiator for radiating heat to deep space and heat conducting means thermally connecting the planar mounting panel to the thermal radiator means for drawing heat away from the planar mounting panel and to the thermal radiator means.

    摘要: A battery system for an body stabilized satellite traveling in a geosynchronous orbit comprises east and second battery modules and similarly facing radiators for discharging beat to deep space. Heat conduction arteries connect each battery module to its associated radiator. An east thermal switch is operable for thermally connecting the first battery module to and from the east facing radiator. Similarly, a west thermal switch is operable for thermally connecting the second battery module to and from the west facing radiator. A computer selectively operates the east and west thermal switches such that, in one instance, for a time between the satellite's emergence from the earth's shadow and its position nearest the sun, the respective thermal switches thermally connect the first battery module to its radiator while thermally disconnecting the second battery module from its radiator. In another instance, beginning when the satellite is nearest the sun and ending as it enters the earth's shadow, the east thermal switch thermally disconnects the first battery module from its radiator while the west thermal switch thermally connects the second battery module to its radiator. In still another instance, beginning when the satellite is in the shadow of the earth, the battery modules are simultaneously thermally connected to their associated radiators. Charging of each battery proceeds while it is thermally connected to its respective radiator.

    摘要: A high capacity broadband service is provided from an Earth orbiting satellite having a payload that includes multiple large antennas, the satellite having an inverted configuration when deployed on orbit. The satellite has an aft surface proximate to a launch vehicle structural interface, a forward surface opposite to said aft surface, and a structure disposed therebetween. In a launch configuration, two or more deployable antennas are disposed, undeployed, on or proximate to and forward of the forward surface; on-orbit, the payload is operable when the satellite is disposed with the aft surface substantially Earth facing while the forward surface is substantially facing in an anti-Earth direction. Each deployable antenna is disposed, so as to be Earth facing, when deployed, in a position substantially forward and outboard of the forward surface.

    摘要: A three-axis stabilized spacecraft having roll, pitch, and yaw axes and when on station in orbit about the earth having a north face and a south face is equipped with a first and second thruster which may be electric thrusters. A first support device mounts the first thruster adjacent the north face and the first thruster is positioned a spaced distance away from the north face in a first direction parallel to the pitch axis and spaced from the pitch axis in a second direction normal to the pitch axis. A second support device mounts the second thruster adjacent the south face, the second thruster being positioned a spaced distance away from the south face in a third direction opposite the first direction and spaced from the pitch axis in the second direction. A gimbal mechanism pivotally mounts the first and second thrusters on the first and second support devices, respectively, for selectively positioning the attitude of the first and second thrusters. The spacecraft includes a system for performing one or more operations including the following: thrusting along the yaw axis to assist in reaching a geosynchronous orbit; reducing the stored angular momentum of the momentum wheels; and north-south station keeping of the spacecraft.
