摘要： A method and a system are described for localisation and tracking of moving vehicles using auxiliary array antennae, dual space-frequency estimators and interferers discriminators. Doppler effect is compensated by performing an estimate of the frequency drift rate. By stamping an absolute time reference for the digital signal samples, the frequency drift rate associated with Doppler effect is calculated and can be compensated. Then, the DoA is statistically calculated by computing the spatial correlation to locate the moving vehicle e.g. an aircraft or spacecraft, taking into account a previously generated parametric calibration model.

摘要： A method of providing an authenticable time-and-location indication using a radio-navigation signal receiver comprises receiving radio-navigation signals broadcast from a plurality of radio-navigation signal sources, at least some of the radio- navigation signals containing one or more cryptographic tokens protected by encryption, the cryptographic tokens being updated from time to time. The receiver retrieves, by decryption, the cryptographic tokens from the radio-navigation signals containing them. The receiver then determines positioning data, representing its geographical position and time, based on the radio-navigation signals received. The receiver generates a digital authentication code using a cryptographic function taking as inputs at least the positioning data and the retrieved cryptographic tokens, and produces a data package including a first part containing the positioning data and a second part containing the digital authentication code.

摘要： A method for radio-navigational determinations using artificial Earth-satellites providing for generation on satellites (1) of a radio-navigational signal by means of modulation of the carrier frequency (fc) by a combination of signals comprising a pseudorandom sequence, navigational data and a synchrocode, and the object/users (2) receiving and processing the radio-navigational signals to determine their co-ordinates, speed and correction to the time scale of the object. According to the invention, an individual carrier frequency (fcj, fck) is used for each satellite or for each pair of satellites (1) mutually opposite in the orbit plane; a common pseudorandom M-sequence with a lower number of elements is used for all the satellites (1) and a bi-binary coding of the navigation data symbols is used as well as a synchrocode with a decreased repetition period and with an increased number of symbols. According to the invention, a satellite radio-navigational system on each satellite (1) in a subsystem for generating and transmitting the radio-navigational signal, and on an object/user (2) in a subsystem for receiving and processing the radio-navigational signal, implements fully the claimed method, thus increasing the probability of high precision navigational determinations at any moment of time due to practically complete exclusion of intrasystem interference, and essentially decreasing the time needed for the navigational determination.
