摘要
Abstract
Compared with BDS and GPS ,the double‐difference ambiguity of relative po‐sitioning lost its integer property .The paper gives relative positioning models of combined BDS/GPS/GLONASS with single‐frequency .Preliminary analyze the positioning perform‐ance of combined BDS/GPS/GLONASS single‐frequency relative positioning with carrier phase observation , and with ambiguity using LAMBDA method , single epoch searching strategy .By short baseline measurement data analysis showed that :compared with single‐frequency relative positioning of single‐system and dual‐system ,single‐frequency relative po‐sitioning of three‐systems can improve the positioning accuracy and fixed rate of ambiguity , and more suitable for urban‐canyons environments .关键词
