摘要： Satellite systems and methods to perform rendezvous and docking between a servicer satellite and an on-orbit satellite, and specifically to satellite systems and methods to perform rendezvous and docking between a servicer satellite and an on-orbit client satellite using electric propulsion thrusters. In one aspect, a servicer satellite with a set of thruster arms each attached to an electric propulsion thruster performs acceleration, deceleration, and steering maneuvers through six degree of freedom positioning of the thrusters, the same set of thruster arms and thrusters performing station keeping of the docked servicer-client satellite system.

摘要： The technology disclosed relates to a multi-satellite system including at least three satellites where at least two of the satellites comprises at least one antenna array for obtaining observation data, and methods for controlling and continuously changing the configuration of a multi-satellite formation including at least three satellites in a formation. The system enables controlling the relative distances between the satellites and continuously changing the configuration and directions of antenna arrays of separate satellites in a multi-satellite formation in that at least one of the satellites comprises a propulsion system for continuously changing the movement and direction of the satellite relative the other satellites in the formation to thereby, in turn, also change the relative distances and directions between the antennas of separate satellites in the formation.

摘要： An electric propulsion simulator console (EPSC) which electronically simulates an electric propulsion assembly of a spacecraft as well as propulsion fuel control components and positioning components of the spacecraft. The EPSC simulates a spacecraft thruster electrical interface can test four thruster interfaces simultaneously and continuously. The simulator additionally facilitates the testing of spacecraft fault detection, isolation, and recovery by simulating failed magnet circuits, open anode paths, and flameout conditions. The EPSC includes an electrical propulsion unit load simulator adapted to receive propulsion unit control signals from a spacecraft under test and a spacecraft propulsion unit positioner simulator the simulator adapted to display a simulated state of three axes of movement for at least one propulsion unit positioner responsive to positioning signals received from the spacecraft under test. A propulsion unit fuel valve simulator is also provided and can display a simulated state of propulsion unit fuel valves responsive to control signals received from the spacecraft under test.

摘要： An aircraft includes a fuselage having an upper surface and a lower surface that define an airfoil shape in cross-section along a vertical plane such that horizontal movement of the fuselage through air produces a lift force in a vertical direction. The aircraft also includes a plurality of modules attached to the fuselage. Each module includes an upper jet engine directed above the upper surface of the fuselage and an opposed lower jet engine directed below the lower surface of the fuselage.

摘要： A passive thermal system for use in a satellite and other aerospace applications includes a container having a heat-pipe working fluid disposed in a first chamber and a Phase Change Material (PCM) disposed in a second chamber that substantially surrounds the first chamber. The first chamber contains a wick for transporting the heat-pipe working fluid. The exterior of the first chamber has fins, etc., that extend into the PCM for heat spreading and increased interface area.
