摘要: A satellite communication system with software defined network orchestration. Implementations include a route management function (RMF) that receives link status from the satellites and determines simple routing tables which are uploaded to the satellites. The routing tables allow the satellites to route data based on a satellite ID placed in a data header to reduce the memory and computing load on satellite resources. Further, implementations include secure user terminal (UT) to UT IP routing in the constellation for direct UT to UT communication. The satellite communication system may combine the benefits of Medium Earth Orbit (MEO) and Low Earth Orbit (LEO) satellite systems into an MEO-LEO satellite system.

摘要: In one example, an antenna system is described. The antenna system includes a primary antenna on an aircraft. The primary antenna is mechanically steerable and has an asymmetric antenna beam pattern with a narrow beamwidth axis and a wide beamwidth axis at boresight. The antenna system also includes a secondary antenna on the aircraft, the secondary antenna including an array of antenna elements. The antenna system also includes an antenna selection system to control communication of a signal between the aircraft and a target satellite via the primary antenna and the secondary antenna. The antenna selection system switches communication of the signal from the primary antenna to the secondary antenna when a performance characteristic for communication with the target satellite satisfies a threshold due to a position of the aircraft relative to the target satellite.

摘要: Systems and methods for controlling satellites are provided. In one example embodiment, a computing system can obtain a request for image data. The request can be associated with a priority for acquiring the image data. The computing system can determine an availability of a plurality of satellites to acquire the image data based at least in part on the request. The computing system can select from among a plurality of communication pathways to transmit an image acquisition command to a satellite based at least in part on the request priority. The plurality of communication pathways can include a communication pathway via which the image acquisition command is indirectly communicated to the satellite via a geostationary satellite. The computing system can send the image acquisition command to the selected satellite via the selected communication pathway. Data from the satellite can be relayed to ground-based stations via one or more relay satellites.

摘要: This is an Improved Radio Communications System called Eyestar. It is a simplex (one way, send or receive) or duplex (two-way, send and receive) Improved Radio Communications System called Eyestar. It provides a solution for quick, low power (0.2 W), reliable beaconing of data from one's satellite. The data is transmitted 24/7 anywhere and anytime with max data rates of 8 Bytes/sec operating continuously. The Simplex and Duplex versions has a Buffer to filter RF output from being damaged; it has a modified the internal firmware to improve broadcast speeds; it provides continuous connectivity for one's satellite in orbit (24/7); the simplex and duplex (they) have worked well in polar and lower inclinations and also for tumbling spacecraft; they need no ground station; they are FCC licensed; and they are less expensive, smaller, and require less power than the other qualified S-band, X-band radios.

摘要: A satellite communication system in which a plurality of satellites each transit about the Earth in a common mid-Earth orbit. The orbit may be configured such that each satellite of the plurality of satellites follows a common, repeating ground track relative to the surface of the Earth. In turn, one or more repeating sky tracks may be defined relative to at least one ground station such that the ground station is in continuous communication with at least one of the plurality of satellites. In an example, a ground station may have visibility to a plurality of repeating sky tracks such that a plurality of discreet communication channels is provided that use different satellites for communication with user terminals of the satellite communications system.

摘要: This disclosure includes various examples and variations of communications networks that employ a satellite network with a plurality of HEO and/or MEO satellites. Regional data centers may be connected to the satellite via gateways. Edge devices may connect to the network through a plurality of edge micro data centers configured in a mesh network to provide distributed and dynamically allocatable compute and storage resources. Each edge micro data center may include a RAN controller to implement an O-RAN network (e.g., via a 5G Node B cell site) to provide end-user devices direct access to the distributed compute and storage resources of the mesh network of edge micro data centers without intermediary backhaul transport layers. Microwave links or other terrestrial network types may be employed to facilitate the mesh network of edge micro data centers.
