Patent number: 10882644Abstract: Techniques for performing spacecraft rendezvous and/or docking include operating a first orbiting spacecraft, the first spacecraft including a sensor arrangement, a first processor and a first inter-satellite link (ISL) arrangement and performing one or both of a rendezvous operation and a docking operation with the first spacecraft and a second orbiting spacecraft, the second spacecraft including one or more actuators. The performing one or both of the rendezvous operation and the docking operation includes determining a pose and pose rate of the second spacecraft relative to the first spacecraft using observations made by the sensor arrangement and determining a desired approach trajectory for the second spacecraft.Type: GrantFiled: October 10, 2017Date of Patent: January 5, 2021Assignee: Space Systems/Loral, LLCInventors: Robert Erik Schwarz, John Douglas Lymer

Publication number: 20200247563Abstract: A spacecraft includes a plurality of deployable module elements, at least one of the deployable module elements including a robotic manipulator, the spacecraft being reconfigurable from a launch configuration to an on-orbit configuration. In the launch configuration, the deployable module elements are disposed in a launch vehicle in a first arrangement. In the on-orbit configuration, the deployable module elements are disposed in a second configuration. The spacecraft is self-assembled by the robotic manipulator reconfiguring the spacecraft from the launch configuration, through a transition configuration, to the on-orbit configuration. The deployable module elements may be in a stacked arrangement in the launch configuration and may be in a side-by-side arrangement in the on-orbit configuration.Type: ApplicationFiled: April 22, 2020Publication date: August 6, 2020Inventors: Robert Erik Schwarz, Robert Edward Helmer, Paul Anthony Briggs, John Douglas Lymer, Alfred Heikal Tadros, Andrew E.

Patent number: 10518909Abstract: A spacecraft including a main body structure and at least a first deployable element is reconfigured from a launch configuration to an on-orbit configuration. In the launch configuration, the first deployable element is mechanically attached with the spacecraft main body structure by way of a first arrangement. In the on-orbit configuration, the first deployable element is mechanically attached with the spacecraft main body structure by way of a second arrangement. Reconfiguring the spacecraft includes detaching the first deployable element from the first arrangement, moving the first deployable element with respect to the spacecraft main body structure; and attaching the first deployable element to the second arrangement.Type: GrantFiled: December 19, 2017Date of Patent: December 31, 2019Assignee: Space Systems/Loral, LLCInventors: Robert Edward Helmer, John Douglas Lymer

Patent number: 10513354Abstract: There is disclosed a Payload Ejection System (PES) able to store any set of payloads for launch and eject that set of payloads at a controlled speed with a low tumble rate while accommodating any offset centre of mass within a restricted volume. The need for ballasting or balancing is eliminated thus freeing up the design space for these payloads. Insensitivity to centre of mass location is enabled by the use of a deployment hinge assembly arrangement which uses two or more non-parallel folding hinge arrangements that allow for linear motion of the output link in one direction while restricting the motion all other directions. One embodiment of the current PES concept uses four (4) hinge panel assemblies, selected to provide optimal stiffness around the entire mechanism. The stiffness of the PES is integral to managing offset centre-of-mass locations by allowing the mechanism to translate the effective force vector to the center of mass location.Type: GrantFiled: July 12, 2019Date of Patent: December 24, 2019Assignee: MACDONALD, DETTWILER AND ASSOCIATES INC.Inventors: Tej Singh Sachdev, John Douglas Lymer, Richard Andrew Bryan, Branko Francetic, Paul Robert Peacock, Peter Panagiotis Krimbalis
