    摘要： A method for radio-navigational determinations using artificial Earth-satellites for generation on satellites (1) of a radio-navigational signal by means of modulation of the carrier frequency (f c ) 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 (f cj , f ck ) 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 for (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.
