    摘要: A method for localizing a terminal includes transmitting the signal by the terminal; receiving the signal by a first and a second satellite; transmitting the signal from each satellite to a receiving station; demodulating the signal received by the first satellite to determine a signal content and the time of arrival of the signal transmitted by the terminal at the receiving station via the first satellite; determining the time of arrival of the signal transmitted by the terminal at the receiving station via the first and second satellite; determining a position for the terminal by triangulation.

    摘要: A method performed on-board by a satellite for processing a signal received from a terminal during a current time interval, includes receiving, during the current time interval, a main signal containing a message from a terminal, each message having a priority level; sampling the main signal to obtain samples; storing the obtained samples into the satellite memory; first demodulating the messages corresponding to the current time interval contained in the samples stored in memory; when the satellite is in the range of a ground station, transmitting to the ground station the content of the memory. The first demodulating includes, for each message of the messages contained in the samples and by priority order: demodulating and decoding the message; forwarding, using direct link or inter-satellite-link, the demodulated message to a ground station; estimating the number of remaining non-demodulated messages in the samples stored in the memory.

    摘要: A method for recovering content such as an HTML page corresponding to a URL address by a client device, includes, based on a URL address corresponding to the content, the client device checks for the presence of the content of the URL address in a cache memory of the client device; in absence of the content of the URL address in the cache memory, the client device creates a short message including the URL address; the message is transmitted to a server device by a one-way transmission protocol without establishment of a connection; the server device downloads the content corresponding to the URL address from the internet network; the content is transmitted to the client device by the server device via a one-way protocol with coding without acknowledgement; the content is received by the client device; and the content is recovered and stored by the client device in the cache memory.

    摘要: A method for generating a circular polarisation signal from at least two transponders of a satellite able to process linearly polarised signals includes: a transmission of at least two linearly polarised signal components so as to produce a circularly polarised signal by at least two transponders of a satellite; processing signals by the two transponders of the satellite to produce a circular polarisation of the signals transmitted by the satellite; ground receiving by at least one circularly polarised antenna; measuring a physical parameter from the received signals, and determining a correction parameter to be applied to the generation of the components of linearly polarised signals; generating a compensation of the components of linearly polarised signals transmitted to the satellite.
