GNSS Precise Relative Positioning Using A Priori Relative Position in a GNSS Harsh Environment [PDF]
Sensors, 2021 To enable Global Navigation Satellite System (GNSS)-based precise relative positioning, real-time kinematic (RTK) systems have been widely used. However, an RTK system often suffers from a wrong integer ambiguity fix in the GNSS carrier phase measurements and may take a long initialization time over several minutes, particularly when the number of ...
