Abstract: A method and a system dynamically adapt a passenger transport capacity of a transport line to the number of passengers determined for the transport line. The system contains a main evaluator configured for automatically determining, as a function of the time, the number of passengers for the transport line, and a processor configured for acquiring the number of passengers as a function of the time, a nominal timetable, and a nominal passenger transport capacity of each vehicle of the line. The processor applies a trained function to the number of passengers, and the trained function has been trained by a machine learning algorithm for predicting a future temporal evolution of the number of passengers. The processor is configured for determining a measure for adapting the transport capacity of the line to the future temporal evolution. The system is further configured for applying the measure to the transport line.

Abstract: Described herein is a method for improving the reception of a satellite navigation message divided in several pages and transmitted by one or several satellites. A satellite navigation message M of k pages is encoded inn pages, and any k retrieved pages from any satellite enables decoding of the original satellite navigation message M. An implementation of the method uses parallel block encoding for a binary erasure channel with high parity and zero overhead, where symbols at a fixed position of all pages are encoded in parallel into shorter codes. This method achieves full page interchangeability in the message transmission, optimizes message reception and reduces decoding cost.

Abstract: Described herein is a method for improving the reception of a satellite navigation message divided in several pages and transmitted by one or several satellites. A satellite navigation message M of k pages is encoded in n pages, and any k retrieved pages from any satellite enables decoding of the original satellite navigation message M. An implementation of the method uses parallel block encoding for a binary erasure channel with high parity and zero overhead, where symbols at a fixed position of all pages are encoded in parallel into shorter codes. This method achieves full page interchangeability in the message transmission, optimizes message reception and reduces decoding cost.

Abstract: The invention introduces “crossed” navigation message authentication, which comprises a) generation and transmission of unpredictable bits periodically from satellites currently not connected to the ground mission segment and b) generation of digital signatures for the data from these satellites, and the transmission thereof through satellites that currently are connected to the ground mission segment. An attacker cannot spoof the navigation message as it contains an unpredictable bit pattern that is verified a few seconds later through a digital signature.

Abstract: The present invention describes a method and a system to compute the time (t1) and the position (P1) of a receiver (102, 805, 901) based on satellite radiofrequency signals without accurate, a priori time or position information and without the need for demodulating data from the signals received by the satellites (103, 800). In particular, the present invention computes the receiver time (t1) and position (P1) by estimating the time offset between the actual time (t1) and an initial time (t0), which can be defined arbitrarily and even have an error of hours or days. The estimation of this time offset is performed by updating Doppler estimations (D(t0), D(t1)) between different times using Doppler change rates.
