FIELD: navigation equipment, using third, two or one navigation satellite in access region. SUBSTANCE: method involves parallel or sequential reception of satellite signals, and using received ephemeris data for calculation of projections, absolute values of N base vectors, cosine values of angles between N base vectors and vectors, which join position vectors of phase centers of satellite antennas, position vector of phase center of antenna of user's navigation equipment, cosine values of their angles, velocity of satellite orbiting movement, radiuses and periods of satellite orbits. Then method involves measurement of distance between phase center of user's navigation equipment and phase centers of satellite antennas using measurement of time shifts between specific code sequences in order to establish system of linear navigation equations, which are differentiated in time. Then method uses measured radial velocities, distance increments, speed of alteration of distance increments in order to detect position coordinates, and values of constituents of velocity vector of phase center of user's navigation equipment antenna by means of solving respective systems of equations. EFFECT: increased precision. 4 cl, 3 dwg
