Antenna system includes an elongated antenna feed tower structure having a tower base at one end which includes a plurality of feet arranged to align with a plurality of predetermined structural mounting points associated with a space vehicle bus. The antenna system also includes a deployable reflector assembly comprising a hub ring. The hub ring includes a reflector deployment mechanism around which a plurality of reflector ribs are disposed. The hub ring is advantageously arranged to engirdle the feed tower assembly. As such, the central aperture is configured to receive the feed tower assembly therein after the feed tower has already been mounted to the space vehicle.

A segmented structure includes at least two panels, a first panel, called the main panel, a second panel, called the secondary panel. The structure further includes at least one deployment device configured to move secondary panel into a storage position or a deployed position. The deployment device has a translation system having an assembly with articulated arms, wherein the translation system is able to generate a movement of the secondary panel in translation in relation to the main panel. The translation system is connected to the secondary panel by an outer end. A rotation system is able to generate a rotation of the translation system and of the secondary panel connected to the translation system, in relation to the main panel.

A foldable satellite dish is provided. The foldable satellite dish has a dish reflector assembly a support housing, and a driving mechanism. The dish reflector assembly comprises four quarter circle shape dish sectors that can be folded and deployed by the driving mechanism. The foldable satellite dish can deploy and fold automatically and smoothly. All the quarter circle shape dish sectors will be secured by the driving mechanism. Compared to traditional satellite dish, the present invention is more flexible and easier to use.

A latch for coupling a first object to a second object is disclosed comprises a primary block coupled to the first object. A locking cam is rotatably coupled to the primary block. A cam track having a sloped surface is in the locking cam. A locking stem slideably engages the primary block and traverses the locking cam. A cam pin is coupled to the locking stem. The cam pin slidably engages the sloped surface for displacing the locking stem between an extended position and a retracted position. A stem head is coupled to the cam pin. A secondary block is coupled to the second object. A cam channel is in the secondary block for receiving the locking stem. A head receiver is in the secondary block for engaging the stem head. The extended position defines an unlocked position and the retracted position defines a locked position.

A segmented structure includes at least two panels, a so-called main panel and a so-called secondary panel, as well as at least one deployment device configured to move the connected secondary panel into a storage position or into a deployed position. The deployment device includes a translation system provided with at least one helical geared motor configured to translate the secondary panel relative to the main panel. The translation system further includes a rotation system configured to rotate the translation system and the secondary panel connected to the translation system, relative to said main panel.

A multi-panel antenna system may be disassembled and packaged into a container with substantially smaller dimensions than the assembled antenna system. The antenna system may include two or more reflector panels, such that a respective reflector panel can include a curved surface that may form a portion of a parabolic reflector, and can include an inter-panel fastener operable to align a side surface of the respective reflector panel with a side surface of another reflector panel. The antenna system may also include a mounting assembly that may be used to fasten a convex side of the two or more reflector panels to a surface external to the antenna system, and a feed assembly that may be attached to the mounting assembly.

A reflectarray antenna comprises panels connected by rotating hinges. The panels are stowed folded around a satellite body and deploy by actuating the spring loaded hinges to extend and form a reflectarray for operation in the K/Ka or X-band. The feed deploys from the satellite body to allow formation of a high gain reflectarray antenna that occupies limited space in small satellite operations.
