    摘要： The integrated platform formed comprises one or more nanosatellites (1), each of which includes at least one sensor module (1.1) bidirectionally coupled to an on-board computer (1.2), which in turn is bidirectionally coupled to at least one communication module (1.3) bidirectionally coupled to at least one communication antenna (1.4). Each communication antenna (1.4) is coupled to at least one ground antenna (2.1) bidirectionally coupled to at least one telecommunication equipment unit (2.2) of one or more ground stations (2). Each of the ground stations (2) is bidirectionally connected to a control server (3) bidirectionally connected to a database (4), which in turn is bidirectionally connected to a market portal server (5), a developer portal server (6) and an application server (7). The control server (3), the market portal server (5), the developer portal server (6) and the application server (7) are bidirectionally connected to client stations (8.1, 8.2, 8.3 and 8.4).

    摘要： Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for determining a set of communication parameters for receiving data transmissions. In some implementations, a method includes receiving a first data transmission sent according to a first communication parameter scheme that includes at least one of a first modulation or a first coding. A second data transmission is received. A second communication parameter scheme of the second transmission is determined. This determination includes identifying a subset of multiple candidate communication parameter schemes determined based on the first communication parameter scheme, identifying, in the second data transmission, a first identifier that corresponds to the second communication parameter scheme, comparing the first identifier to a respective identifier for each communication parameter scheme in the subset, and determining, as the second communication parameter scheme, a communication parameter scheme in the subset that has an identifier that matches the first identifier.

    摘要： An apparatus for satellite selection within a multi-satellite communication system, comprising an antenna, receiver, and transmitter, and a processing module configured to calculate a normalized distance metric for the plurality of user spot beams of a first and second satellite, select the user spot beam with the lowest normalized distance metric, and determine which of the at least first or second satellite is transmitting the selected user spot beam. Further, a method for increasing the aggregate capacity of a satellite communications network, comprising identifying high traffic regions within a coverage area of a first satellite, determining which user spot beams of the first satellite are available to each of the identified regions, determining a normalized distance metric for each user spot beam identified, and plotting a second beam pattern of a second satellite to produce at least one user spot beam with a lower normalized distance metric.

    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： A satellite communication system, a method and a system are provided. In one aspect of the invention, an outdoor unit power source is connected to a switch of a satellite modem of an indoor unit. When the satellite modem receives a first signal from a wireless device, a first switch control signal is sent to the switch to open a connection between the outdoor unit power source and an inter-facility link connected to an antenna of an outdoor unit, thereby preventing power from flowing through the inter-facility link. When the satellite modem receives a second signal from the wireless device, a second switch control signal is sent to the switch to close a connection between the outdoor unit power source and the inter-facility link, thereby causing the power to flow through the inter-facility link. Other wirelessly received signals may cause various control signals to be sent via the inter-facility link.
