摘要： A beam plan that defines beams generated by a satellite that satisfy a set of communication service requirements is obtained. Fade condition information that indicates an amount of fade at particular geographic areas for one or more of the beams is obtained. 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.

摘要： 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 communicated to a first and a second switch, respectively. 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.

摘要： An apparatus includes feeds to form analog beams. The feeds are divided into panels. The apparatus includes processing circuitry that divides a target area for communications coverage into regions, including a first region and a second region neighboring each other. The processing circuitry generates, for the first region, a first plurality of analog beams, forming a first cluster. The processing circuitry generates, in the first cluster from the first plurality of analog beams, a first plurality of hybrid beams arranged in a first arrangement in the first cluster. The processing circuitry generates, for the second region, a second plurality of analog beams, forming a second cluster. The processing circuitry generates, in the second cluster from the second plurality of analog beams, a second plurality of hybrid beams arranged in a second arrangement that is adjacent to the first plurality of hybrid beams in the first arrangement.

摘要： In one implementation, receive signals may be received by a satellite using corresponding receive elements. The receive signals may form one or more receive beams at one or more receive frequency channels. Transmit signals may be calculated by the satellite by linearly combining the obtained receive signals using transform data. The calculated transmit signals may form one or more transmit beams at one or more transmit frequency channels. The calculated transmit signals may be transmitted by the satellite using corresponding transmit elements.

摘要： 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.

摘要： 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.

摘要： 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. The beam former processor determines terrestrial regions for transmitting the group of signals. The beam former processor identifies a subset of feeds that are configured to form beams covering the terrestrial regions. The beam former processor controls the switching circuitry to route the group of signals from the plurality of amplifiers to the subset of feeds through the switching circuitry, such that the subset of feeds are enabled to form beams that cover the terrestrial regions based on the group of signals.
