FIELD: electricity.
SUBSTANCE: during method realisation, a composite signal is received. Composite signal includes a signal of direct path with limited pass band, and at least one multipath signal with limited pass band, every of which is modulated with periodical phase reversals. Composite signal is measured depending on time during time interval, comprising at least one of periodical phase reversals. Phase error between composite signal and direct path signal, provided by multipath signal, is determined, using measured composite signal depending on time and previously specified characteristic of filter, corresponding to filter used to limit pass band of direct path signal and multipath signal. Phase error is corrected in process of navigation calculations.
EFFECT: weakening of error caused by phase multipath propagation.
