FIELD: physics. ^ SUBSTANCE: navigation is performed using low earth orbit (LEO) satellite signals, as well as signals from two sources of ranging signals for determining associated calibration information, where a position is calculated using a navigation signal, a first and a second ranging signal and calibration information. Also possible is providing a plurality of transmission channels on a plurality of transmission time intervals using pseudorandom noise (PRN) and merging communication channels and navigation channels into a LEO signal. The method also involves broadcasting a LEO signal from a LEO satellite. Also disclosed is a LEO satellite data uplink. The invention also discloses various approaches to localised jamming of navigation signals. ^ EFFECT: high efficiency and ensuring navigation with high level of integration and security. ^ 14 cl, 34 dwg |
