摘要： Embodiments of the present invention comprise a signal processing method and apparatus for use in a satellite payload in which an input RF signal received at a receiver antenna is modulated by using a single optical carrier at the input of an optical modulator. The optical domain signal is processed and is subsequently combined with a single unmodulated optical LO tone to provide an output RF signal for radiation by a transmitter antenna or for further digital processing by an on-board processor. This results in a clean generation of the frequency-converted RF signal at the output of the opto-electrical conversion stage.

摘要： Measures, including a method, system, and computer program, for performing in-mission photogrammetry while an imaging platform is surveying a target environment. A plurality of images of the target environment are captured by the imaging platform. At the imaging platform, a representative subset of images is identified from the captured plurality of images. The imaging platform transmits the identified representative subset to a processing node. At the processing node, the transmitted representative subset is processed to generate a virtual model of the target environment.

摘要： There is provided a method of assigning use of a bandwidth for radio communication. The method includes the following steps: generating an initial frame, the initial frame including a series of allocations; generating a further frame, the further frame including a series of allocations; repeating the step of generating a further frame to generate a matrix of allocations; shuffling at least two columns or at least two rows within the matrix; selecting one or more columns or rows in the matrix, wherein each selected column or row represents a sequence; assigning use of the bandwidth according to the one or more selected sequences; and transmitting one or more data streams on the assigned bandwidth.

摘要： A system for transferring a fluid from a first spacecraft to a second spacecraft. The first spacecraft includes a fluid transfer system comprising: a pressurant supply system, a first fluid tank to store a fluid to be transferred, one or more transfer feedlines to provide fluidic connection between the first fluid tank and the second spacecraft, a connector for connecting the first spacecraft to the second spacecraft, an accumulator tank comprising a first portion connected to the pressurant supply system, a second portion configured in fluidic communication with the one or more transfer feedlines, and a flexible separator to separate the first portion and the second portion. The pressurant supply system supplies pressurant gas to the first fluid tank for pressurising the first fluid tank and to supply pressurant gas to the first portion of the accumulator tank for pressurising the first portion of the accumulator tank.
