FIELD: spacecraft navigation system.
SUBSTANCE: group of inventions relates to spacecraft navigation systems (SC). Method comprises determining angles between axes of receiving antennae and directions to navigation satellites (NS) with frequency separation of signals, comprising pairs of satellites emitting radio signals at one frequency, determining the current altitude of the SC orbit, recording the time of departure from the horizon of one of the pair of satellites, tracking signals of the first and second satellites of the pair are made with antennas, for which the first of the pair of satellites is in the field of view of one antenna, and the second of the satellites of the pair is in the field of view of the other antenna. First of the satellites of the pair is outside the field of view of the second antenna, and the second of the satellites of the pair is outside the field of view of the first antenna; SC coordinates are determined over all NSs which are not obscured by the Earth.
EFFECT: high accuracy of determining coordinates of SC.
