FIELD: satellite communication.
SUBSTANCE: method of tracking multiple signals from one satellite comprises (s1) receiving a first signal transmitted by satellite 2; receiving at least a second signal (s2) transmitted by the same satellite; applying a pre-filtering process to determine aggregate in-phase and quadrature components of a first, a second signal and optionally any other signals; and application of filtration process to combined in-phase and quadrature components of first and at least second signals to determine distance (r) and rate of change of distance (v) to satellite; wherein filtration process comprises application of Kalman filter.
EFFECT: technical result is determination of distance and rate of change of distance from one satellite with improved signal-to-noise ratio.
