NAVIGATION SYSTEM AND METHOD OF RESOLVING INTEGER AMBIGUITIES USING LIMITATION AMBIGUITY DOUBLE DIFFERENCE

摘要

FIELD: radar ranging and radio navigation.;SUBSTANCE: state of plurality of global navigation satellites (110-1, 110-2, 110-N) is calculated on basis of received satellite navigation measurements. Base lines are identified, each corresponding to a pair of reference stations (140-1, 140-2, 140-M). For each identified base line is calculated floating and integer value for integer ambiguity double difference. Integer ambiguities of double difference are identified, which satisfy a set of preset conditions, and calculated state of plurality of global navigation satellites, in accordance with an integer limitation used to each integer ambiguity double difference which satisfy a set of preset conditions. Correcting information is calculated from specified calculated state of plurality of global navigation satellites.;EFFECT: improved correction of information for navigation receivers (120) by means of resolution of integer ambiguities in range measurements of reference stations using restrictions of integer ambiguity of double difference.;28 cl, 9 dwg, 1 tbl
