Abstract: An apparatus includes a plurality of feeds that form analog beams. The plurality of feeds is divided into a plurality of panels, each panel including one or more feeds from the plurality of feeds. The apparatus also includes processing circuitry, which determines a target area for communications coverage and divides the target area into a plurality of regions. The processing circuitry generates, for each region, a plurality of analog beams. A subset of panels of the plurality of panels generates one or more analog beams of the plurality of analog beams. The plurality of analog beams covering each region forms a cluster. The processing circuitry generates, in each cluster, one or more hybrid beams. Each hybrid beam is a digital beam that is generated by combining one or more analog beams of the plurality of analog beams corresponding to the cluster.

Abstract: A request to register a function of the application module with a system manager may be received. The request may describe one or more inputs to the function, one or more outputs of the function that are used to generate a beam plan for a satellite, and one or more capabilities that the satellite must have for the function to be used. It may be determined whether one or more capabilities of the satellite satisfy the described one or more capabilities that the satellite must have for the function to be used. In response to determining satisfaction, an indication that the function of the application is available may be provided to a client. A request may be received from the client to generate the beam plan for the satellite using the function. The beam plan for the satellite may be obtained using the one or more outputs of the function.

Abstract: Information associated with a communication service need of the user is received from a user of a client computer system. A set of communication service requirements that indicate satellite resources required to satisfy the communication service need of the user are computed based on the received information, and transmitted to a server computer system. A first beam plan that satisfies the set of communication service requirements is received from the server computer system. The first beam plan includes information on satellite beams and spectra for allocation to the user when the first beam plan is deployed to provide a communication service to the user that satisfies the communication service need of the user. Instructions are transmitted to the server computer system to deploy the first beam plan. Information is received from the server computer system indicating that the first beam plan is deployed.

Abstract: Beamforming in a satellite communications network includes determining a first delay imparted to signals redirected by a first reflecting dish in a satellite, the first delay being caused by motion of the first reflecting dish relative to the satellite. A second delay imparted to signals redirected by a second reflecting dish in the satellite is determined, the second delay being caused by motion of the second reflecting dish relative to the satellite. Calculating, using the determined first and second delays, beamforming coefficients that enable the generation of a single beam by combining a group of signals that includes a first signal redirected by the first reflecting dish and a second signal redirected by the second reflecting dish.

Abstract: A network device determines an exposure time associated with an image sensor coupled to a spacecraft for capturing an image of a target object orbiting the Earth. The network device computes a maximum relative angular velocity associated with the target object based on the exposure time and a dimension of a pixel of the image sensor. The network device identifies a first pointing direction of the image sensor for initiating a search for the target object. The network device generates a first angular velocity probability distribution map for the target object and divides the first angular velocity probability distribution map into a first set of angular velocity regions (AVRs). The network device selects a first AVR from the first set of AVRs for scanning by the image sensor and generates a search schedule that includes a first entry for informing the spacecraft to scan the first AVR.

In response to determining that the beam plan satisfies the protection module, the beam plan may be transmitted to the satellite.

Abstract: A beam former processor receives a group of signals for transmission through the plurality of amplifiers, wherein the group of signals is less than a total number of feeds in an antenna array.

A modification to the beam plan that mitigates the amount of fade at the particular geographic areas for the one or more of the beams is determined. The beam plan is modified based on the determined modification.

Abstract: Receive signals may be combined to form receive beam signals at multiple receive frequency channels. The receive beam signals may be partitioned by receive frequency channel into multiple groups of receive beam signals, each group corresponding to a different frequency spectrum and the multiple groups including a first group and a second group.

The first and the second group of receive beam signals may be switched by the first switch and the second switch, respectively, to generate a first and a second group of transmit beam signals. Transmit beam signals that include the first and the second group of transmit beam signals may be combined to form transmit signals to be transmitted using corresponding transmit antenna elements to form one or more transmit beams at multiple transmit frequency channels.

Abstract: In one implementation, a minimum metric function with an output representing a metric of a satisfaction of transmission requirements for a satellite communications system configured to produce at least two beams may be generated. The minimum metric function may be a function of beam weight parameters including a first and second set of beam weight parameters representing output signals of high power amplifiers used to form a first and second beam, respectively. An output value of the minimum metric function may be calculated using initial values for the beam weight parameters. A direction to modify the values of the beam weight parameters may be determined based on the calculated output value. Updated values of the beam weight parameters may be determined based on maximizing the output value of the minimum metric function by moving the values of the beam weight parameters in the determined direction.
