DOCKING SYSTEM AND METHOD FOR SATELLITES
The present invention relates to a service satellite having a body, a controller and a docking unit. The docking unit includes at least two foldable, adjustable gripping arms pivotally mounted on the satellite body, each gripping arm being pivotable relative to the satellite body, and a gripping end at each free end of the gripping arms, wherein the gripping ends are adapted and configured to capture and grip a target portion of an orbiting satellite. Each gripping arm is controllable independently by the controller, which coordinates the motion of the arms. The service satellite also includes a propulsion unit including a first thruster mounted adjacent a Nadir end of the service satellite body, and a balance thruster, the balance thruster being distanced from the first thruster and facing a different direction than the first thruster, propellant for the thruster and the balance thruster; and means for aligning the thrusters so that a thrusting vector passes through a joint center of gravity of the service satellite and the serviced satellite.
SHOCK REDUCING TAPE SPRING HINGE
Provided is a shock reducing tape spring hinge including fixing members fixed to at least two objects, respectively, a thin shell type tape spring having both end portions that are fastened to the fixing members, respectively, and a shell-shaped damping plate aligned with the tape spring, the damping plate having both end portions that are fastened to the fixing members, respectively. The damping plate and the tape spring may be configured to connect the at least two objects being spaced through the fixing members, and the damping plate may be configured to reduce a deployment shock occurring when the tape spring is deployed.
Satellite boom hinge actuator using drive chain with flexible and rigid characteristics
A flex-drive actuator for a satellite boom hinge or other hinge applications. Using a motor-driven cog and a unique drive chain, the hinge can be reversibly driven between open and closed positions, thereby deploying or stowing the boom and attached payload. The chain includes links designed so that, when bent in one direction, the chain pre-buckles into a rigid circular arc form that matches the deployment path of the hinge. This pre-buckling essentially converts the chain into a rigid gear segment that can carry a moment to actuate the hinge. As the cog retracts the chain and the hinge closes, the circular shape of the chain de-buckles on the free side of the cog, where the chain can be stored as a straight section inside of a boom tube or folded into a magazine. The flex-drive actuator can accommodate any desired actuation angle by addition of links to the chain.
SPACECRAFT FOR SPACE DEBRIS REMOVAL
A spacecraft for removing space debris is disclosed. The spacecraft includes a satellite bus, a shield member foldable on an outer side face of the satellite bus and disposed facing towards space debris to reduce a movement speed of the space debris, and a support member configured to support the shield member with respect to the satellite bus, in which the shield member includes a central panel configured to overlap one face of the satellite bus, a plurality of first panels connected to peripheral sides of the central panel and radially extended, and a plurality of second panels located between the first panels.
Antennas for small satellites
Various embodiments of the present invention include assemblies and methods for utilizing antennas with high gain in small satellites. In one embodiment, a satellite comprising a payload configured for transmitting data is provided. The payload may include various components of the satellite, such as the attitude control system, electrical power system, and/or communication system. The satellite may be configured to communicate with one or more ground stations. The satellite includes a support structure comprising at least one deployable panel, wherein the support structure houses the payload. The satellite also includes at least one antenna coupled to the support structure, wherein the deployable panel is configured to cover the antenna in a non-deployed state and to expose the antenna in a deployed state.
Methods and Apparatus for Deployable Sparse-Aperture Telescopes
An imaging system includes a metering structure and a plurality of foldable members disposed around a periphery of the metering structure. Each foldable member in the plurality of foldable members includes an arm comprising a strain deployable composite and a reflector disposed on the arm. The arm in a respective foldable member in the plurality of foldable members is configured to hold the respective foldable member toward the metering structure in a first state and to hold the respective foldable member away from the metering structure in a second state such that the reflector of the respective foldable member forms part of a sparse aperture in the second state.
Starshade with attributes facilitating assembly
An exemplary starshade comprises a tensegrity truss structure having a central hub with radially extending, telescoping booms. Telescoping tension struts connected to the central hub and booms provide a compressive force on the booms during final truss deployment. Opaque petals, not supported by the tensegrity truss structure prior to its final deployment, are each sequentially placed on and attached to the tensegrity truss structure in side by side position to form a concentric ring of petals spaced apart from the central hub. A fan fold covering, not supported by the tensegrity truss structure prior to its final deployment, is placed on and attached to the tensegrity truss structure to form an opaque, concentric inner ring about the central hub. An outer edge of the inner ring is adjacent an interior edge of the concentric ring of petals to block light from the petals to the central hub.
Solar Panel Hinge Release Mechanism
A deployment system for solar panels has the panels spring loaded to deploy, but held folded against a satellite framework, held folded by trigger bars engaging slots or notches in hinge bodies holding the solar panels. A remotely-operable linear actuator moves the trigger bars to disengage the trigger bars to release the panels to deploy.
Space vehicle with customizable payload and docking station
A black box space vehicle solution may allow a payload developer to define the mission space and provide mission hardware within a predetermined volume and with predetermined connectivity. Components such as the power module, radios and boards, attitude determination and control system (ADCS), command and data handling (C&DH), etc. may all be provided as part of a stock (i.e., core) space vehicle. The payload provided by the payload developer may be plugged into the space vehicle payload section, tested, and launched without custom development of core space vehicle components by the payload developer. A docking station may facilitate convenient development and testing of the space vehicle while reducing handling thereof.
Morphing self-stiffening array (MOSSA) and hinge
A self-deployable array of panels includes a plurality of panels, each panel having a first compressed panel thickness state and a second expanded panel thickness state, and including a spring bias element biased to the second expanded panel thickness state. A plurality of locking hinges hingedly couple each of the panels to an adjoining panel. Each locking hinge is biased to an open position. A release of stored potential energy of both of the spring bias element biased to the second expanded panel thickness state, and the locking hinges biased to the open position causes the self-deployable array of panels to self-deploy from a folded stowed state. A single part offset locking hinge is also described.
