    摘要: A method and apparatus for providing half-duplex communications for a Very Small Aperture Terminal (VSAT) operating on a continuous received stream is disclosed. The method includes: decoding the continuous received stream to establish synchronization with the continuous received stream; locating, in the continuous received stream, a time plan including a receiving timeslot and a transmitting timeslot; demodulating the continuous received stream by adapting to a timing and frequency variation of the continuous received stream in the receiving timeslot, freewheeling the adapting of the continuous received stream during the transmitting timeslot, and resuming the adapting of the continuous received stream when the transmitting timeslot ends; stopping a receiving of the continuous received stream during the transmitting timeslot; and transmitting from the VSAT during the transmitting timeslot. The freewheeling includes saving a signal acquisition parameter at the start of the transmitting timeslot and restoring the saved signal acquisition parameter at the end of the transmitting timeslot.

    摘要: L'invention concerne un procédé et une architecture système permettant d'établir de manière dynamique un ou plusieurs tunnels chiffrés sur des réseaux de communication à bande contrainte. Elle permet notamment de chiffrer un ou plusieurs flux de données tout en garantissant la qualité de services sur les systèmes à bande contrainte, en particulier pour les flux chiffrés de type voix sur IP (protocole internet) ou de type données ou en anglo-saxon Data. Ces tunnels sont ainsi adaptés au plus juste aux flux de données utiles tout en permettant de contrôler et d'affecter les valeurs nécessaires à la qualité de service ou QoS sur ces réseaux.

    摘要: An orthogonal frequency division multiple access (OFDMA) scheme is used in a satellite environment to reduce narrowband interference, impulse noise, and signal degradation. The symbol timing of each of the satellite network's multiple terminals may be synchronized, and their frequency separation chosen to obtain near orthogonality condition at the reception, between the wanted demodulated channel, and the transmissions on neighbor channels. The establishment of symbol synchronization between various remote terminals may utilize a central clock which may be recovered from a reference downstream channel from one or more satellites; or where two or more satellites are utilized, the satellites may coordinate to provide a single reference clock to the remote user terminals. The terminals may be provided with additional satellite location information relating to slight movement of the satellites around a nominal location so that the timing of transmissions may be corrected based on a tracking algorithm for detecting slight movement of the satellites. The tracking algorithm may be accomplished with individual timing correction to each of the remote terminal's transmissions. A central hub may enforce global timing by utilizing an individual timing correction loop over the network, and enforce global timing synchronization by sending frequent individual timing correction requests and receiving acknowledgements.

    摘要: A system for directing an antenna (111) for transmission over a two-way satellite network is disclosed. A transceiver (109) is coupled to the antenna (111); the transceiver (109) transmits and receives signals over the two-way satellite network. A user terminal (101) is coupled to the transceiver (109) and executes an antenna pointing program. The program instructs a user to initially point the antenna (111) to a beacon satellite (107) using predefined pointing values based upon the location of the antenna (111). The program receives new antenna pointing parameters that are downloaded from a hub (113) over a temporary channel that is established via the beacon satellite (107). The program displays the new antenna pointing parameters and instructs the user to selectively re-point the antenna (111) based upon the downloaded new antenna pointing parameters.

    摘要: A method and apparatus for zero interference multi-gigabit inter-satellite communication between system satellites (300) and client satellites (301) using millimeter wave beams at transmit and receive frequencies that are aligned to the peak atmospheric molecular absorption frequencies in the electromagnetic spectrum (Fig. 1). The narrow low power beams are accurately steered within a restricted set of directions (Fig. 5) that prevent interference to other space borne radio receivers whether in geostationary or low earth orbits and cannot interfere with terrestrial receivers due to atmospheric absorption. The apparatus comprises an integrated electronically steered 2-D phased array (401), transceiver and baseband integrated circuits (402, 403) with a beam controller (404) coupled to the spacecraft attitude determination and control subsystem (407), central processing unit (406) and solid state storage device (405).
