Abstract: A quantum telecommunications network includes nodes, typically on the ground; a conventional telecommunications network connecting the nodes to one another; and at least one satellite or airborne carrier able to generate and transmit multiplets of entangled photons to the nodes. The nodes are configured to collect photons from the satellite, take joint quantum measurements and exchange conventional information with other nodes via the conventional telecommunications network. Node and satellite payload for such a quantum telecommunications network. Method for quantum telecommunications by way of such a network.

Abstract: A system and method are provided for determining a distribution of a position error of a receiver of localization signals, the signals being sent by at least one satellite. The system includes the receiver, one position of which is known as first position and is affected by an error, known as first error, having a distribution, known as first distribution, a first device for determining positions of the satellite(s), known as second positions, a device for transmitting the second position of the first determination device to the receiver, and the first distribution is defined by at least one first cumulant, of higher-than-second order.

Abstract: An adaptive method for estimating the electron content of the ionosphere comprises: collecting a set of measurements carried out by a plurality of beacons receiving radio frequency signals transmitted by a plurality of transmitting satellites; computing coordinates of the points of intersection between the transmission axis of the signals and a surface surrounding the Earth, and of a vertical total electron content determined at each of these points; computing a vertical total electron content for each of the nodes of an initial mesh of the surface; a statistical dispersion analysis of the vertical total electron content; a computation step making it possible to define a suitable statistical estimator, or a computation step making it possible to generate a suitable mesh of the surface; a statistical error analysis making it possible to select between a validation of the adaptation of the method and a stopping of the method.
