METHOD OF AMBIGUITY RESOLUTION OF PHASE MEASUREMENT IN GPS SYSTEM Russian patent published in 2003 - IPC

FIELD: radio navigation. SUBSTANCE: method can be used in equipment of users of satellite radio navigation system GPS in which pseudo-ranges to navigation satellites are measured by phases of carrier frequencies. Technical result of invention lies in expanded range of unambiguous measurement of phase, in enhanced accuracy and reliability of navigation determinations with use of measurement by phase of carrier frequencies and in diminished complexity of software and hardware approaches to equipment of users of satellite radio navigation system. This is achieved thanks to utilization of phase measurements on three carrier frequencies, to measurement of pseudo-range with use of range-finding code of standard precision, to synthesis of additional length of wave and to measurement processing with employment of body of mathematics of theory of numbers. EFFECT: enhanced accuracy and reliability of navigation.
