Abstract: This paper presents two novel concepts to improve the precision of global positioning system (GPS). First, observations of the low cutoff angle are applied to GPS positioning for obtaining more information to enhance ...

Abstract: This study selected five indexes to determine the relationship between data quality and positioning precision. These indexes are multipath on L1, multipath on L2, observations by cycle slips, clock offset, and clock ...

Abstract: Sea surface height (SSH), a measurement widely used in marine science, can be used to compute the marine gravity field while providing underlying information on the ocean current, tide, and geoid. A traditional SSH measurement ...

Abstract: The number of global positioning system (GPS) tracking stations is increasing, primarily because the stations are multifunctional. In civil engineering, they can be used for precision positioning; in the earth sciences, ...
