The invention relates to the field of
satellite navigation and radio positioning, and discloses a ground-based high-precision regional positioning
navigation system and a ground-based high-precision regional positioning navigation method. The ground-based high-precision regional positioning
navigation system comprises a plurality of distributed navigation base stations, a datum
station and a monitoring
station, wherein each navigation
base station has a navigation
signal broadcasting function, is equipped with transmitting and receiving antennas, and adopts a
broadband variable-frequency channel design; 2) the navigation base stations and the datum
station adopt a bidirectional
time synchronization method to achieve
time synchronization among the navigation base stations, and the datum station has a GNSS time
reference function; the monitoring station has a navigation
signal quality monitoring, evaluation and
calibration function, and the monitoring station and the datum station can beco-locational. The invention further discloses a high-precision positioning method, which determines initial position coordinates of a
receiver based on a single-difference
pseudo code phase measurement value, and assists in completion of carrier
ambiguity resolution and high-precision positioning. The ground-based high-precision regional positioning
navigation system has the advantages of high environment adaptability, high positioning precision, high anti-interference performance, easy deployment, low cost,
scalability and GNSS
system cooperative work capability.
