An antenna assembly has a solar layer having one or more solar cells generating solar power, an antenna layer connected to the solar layer and having electronic components utilizing the solar power generated by the solar layer, and a thermal dissipation device dissipating heat locally at the antenna assembly. A large number of antenna assemblies are connected to form an antenna array in which heat is generated locally at each antenna assembly and dissipated locally at each antenna assembly.

An antenna system is configured for use in Low Earth Orbit (LEO) around Earth. The system has a plurality of antenna satellites coupled together to form a phased array. Each of the plurality of antenna satellites have an antenna body with an antenna and a solar cell. A processing device determines an orientation of the plurality of antenna satellites and position the phased array in the orientation based on an analysis of the solar cell of the antenna bodies facing the sun, the antenna of the antenna bodies facing the Earth, and maintaining a torque equilibrium of the phased array.

Small, low-cost satellite systems, like CubeSats or other microsatellites, can exhibit reduced reliability relative to higher-cost satellite systems. This can result in difficulty identifying, communicating with, and tracking such satellite systems when they fail. Provided herein are reliable, low-cost, low-energy, turn-key systems for identification and tracking of small satellites that can be readily added to a microsatellite with minimal integration costs and while occupying a minimal amount of volume, mass, and external area of the host satellite. These systems are electrically isolated from the satellite bus, being powered by internal batteries or other separate energy sources and providing reliable identification and tracking even when the other systems of the satellite have failed. These improved identification and tracking systems include space environment sensors to maintain the system in a very-low-power state while the system is in vehicle processing and transit on Earth, extending device lifetime and reducing cost and weight.

The system is configured to generate a display of a tagging interface. The tagging interface may include a stitching selector. In response to a user selection of (1) a destination element that includes a first name identifier, (2) a source element that includes at least one of the plurality of pixels such that at least one of the plurality of pixels corresponding to longitude-time points comprising a second name identifier, and (3) the stitching selector, the system can be configured to indicate that the source element comprises the first name identifier.

A satellite is disclosed, including a body having an additively manufactured wall panel and a communication device connected to the body. The wall panel includes a facesheet and a stiffening structure extending from a first side of the facesheet. The communication device is configured to send and receive data while in space.

A satellite is disclosed, including a body and a communication device attached to the body. The body has an additively manufactured external wall structure at least partially forming an enclosed compartment, and the communication device is configured to receive and transmit data while in space.

There is provided a satellite network for data communication, the network comprising a plurality of satellites arranged in medium Earth orbit (MEO) in a plurality of orbital planes such that a plurality of satellites are provided in each orbital plane, each satellite being operable to communicate with at least one terrestrial user terminal and comprising at least one communications antenna operable to generate a spot beam on a predetermined selected terrestrial region to enable said one or more terrestrial user terminals to receive and/or send data via the spot beam. The plurality of satellites is arranged such that the spot beams of at least two satellites are operable to cover the same terrestrial region at any one time.

A satellite comprises a body and a generally planar structure extending from the body. One or more radio frequency “RF” antennas, an amplification system for RF signals, and a power distribution system for the amplification system are mounted on the generally planar structure. Two or all of the power distribution system, the one or more RF antennas and the amplification system are arranged on respective parallel boards (310, 312, 314) forming part of the generally planar structure (300). One or more of the parallel boards (310, 312, 314) and the components mounted thereon may be connected to another similar board to form, respectively, a larger power distribution system, antenna array or amplification system, for example arranged in a plurality of modules, each comprising at least one antenna, at least one power distribution system and at least one amplifier supported on at least two respective boards. A satellite may be manufactured by assembling the modules to form a generally planar structure, and attaching the planar structure to

A universal external port is proposed to add new functionality to or replace existing functionality of an already deployed spacecraft (e.g., a satellite in orbit). The universal external port is mounted on an external surface of the spacecraft and configured to connect to different types of external modules that have different functions, without removing components from the spacecraft other than one or more components of the universal external port. A communication interface onboard the spacecraft is configured to wirelessly receive a software patch from an entity remote from the spacecraft (e.g., from a ground terminal or other spacecraft) to program the spacecraft to change operation of the spacecraft to utilize the external module when the external module is connected to the universal external port.

A free-floating spherical gimbal (“gimbal”) that includes a moving portion substantially spherical in shape and partially enclosed within a larger spherical and stationary cavity. The moving portion of the spherical gimbal is maintained in a location without direct mechanical contact with the stationary cavity.
