Abstract: An earth station transmitter device is arranged for generating a signal to be transmitted to an earth station receiver device of a satellite communication system. The earth station transmitter device includes: shaping encapsulation for shaping and encapsulating downlink data traffic based on a modulation and coding decodable by an earth station receiver device. The shaping encapsulation is arranged to output downlink baseband frames, and further encapsulation is arranged to receive the downlink baseband frames and to generate uplink baseband frames by segmenting the downlink baseband frames based on a modulation and coding decodable by a satellite receiver device, encoding and modulation means for converting the uplink baseband frames into an uplink transmission signal using the modulation and coding decodable by the satellite receiver device.

Abstract: An earth station transmitter device is arranged for generating a signal to be transmitted to a plurality of earth station receiver devices of a satellite communication system. The earth station transmitter device comprises a plurality of shapers, each arranged for shaping and encapsulating data traffic to a different subset of earth station receiver devices; obtaining for each subset a virtual carrier outputting at a virtual carrier symbol rate a plurality of virtual carrier baseband frames. A modulator includes a time slice selector arranged for receiving and storing the virtual carriers outputted by the plurality of shapers, for selecting a stored virtual carrier baseband frame from a list of allowable virtual carriers as next frame to be multiplexed on a single stream, and for assigning to the selected virtual carrier baseband frame, from a list of allowable time slice numbers.

Abstract: A method for a logon procedure in a satellite communication system is provided including at least one terminal, a satellite and either a gateway proxy on-board the satellite or a gateway. The method includes transmitting a logon burst signal from a terminal of the satellite communication system to the gateway proxy on-board the satellite or the gateway. The logon burst signal includes one or more transmit parameter fields, each transmit parameter field corresponding to a signal transmit time or a signal transmit level or a signal transmit frequency of the logon burst signal in the terminal.

Abstract: A satellite communication system is arranged for consecutively illuminating a plurality of contours on earth. The satellite communication system includes a modulator adjusting its transmission of data and dummy data to detected switching time instants, without causing too long delays or buffer overflows, or without impacting a return link synchronization. Traffic can be seamlessly switched to a redundant transmitter which is aligned with the beam hopping satellite to efficiently and reliably achieve synchronization.

Abstract: An earth station transmitter device is arranged for generating a set of data to be transmitted to an earth station receiver device of a satellite communication system. The earth station transmitter device comprises: encoding and modulation means for mapping a plurality of baseband frames; physical layer framing means arranged for inserting in front of each frame of encoded and modulated symbols; converter means for converting a super-frame preamble; super-frame generator means arranged to prepend a first subset of capacity units corresponding to the super-frame preamble to a second subset of capacity units of the plurality corresponding to the plurality of physical layer frames.

Abstract: A controller device for a satellite communication system has one or more beam hoppers during a hopping period which each illuminate a plurality of contours according to a hopping plan indicating an order in which the plurality of contours is illuminated. The controller device comprises a dynamic hopping plan calculation module for calculating the hopping plan and is arranged for conveying the calculated hopping plan to a transmitter of the satellite communication system. The dynamic hopping plan calculation module is arranged to calculate the hopping plan by subdividing, per beam hopper, the hopping period in at least two scheduling frames, the at least two scheduling frames forming the calculated hopping plan. Each scheduling frame comprises hopping slots each indicating a contour to be illuminated.
