METHOD TO MEASURE PSEUDORANGE TO SPACECRAFT OF SATELLITE NAVIGATION SYSTEM AND SYSTEM FOR ITS REALISATION Russian patent published in 2011 - IPC G01C21/24

Abstract RU 2415384 C1

FIELD: instrument making.

SUBSTANCE: system comprises receiving antenna of navigation signal, two digital receivers of navigation signal, two selectors of measurements, two filters of random error component, signal splitter, analyser of synchronism and computer. At that navigation signal is received from one receiving antenna by two navigation receivers via navigation signal splitter. Then random component of measurements error is identified, and synchronism of random measurements error component is analysed, which is excluded from subsequent processing, if phases of measurement signal error are in-phase. If phases of measurement signal error are not in-phase, then measurement signal is averaged, and pseudorange is measured to spacecraft of satellite navigation system.

EFFECT: higher accuracy of measurement.
