Abstract:
The Multi-GNSS observations from an onboard receiver were retrieved using kinematic Precise Point Positioning (PPP) method. The solution using only Global Positioning System (GPS) observations is the GPS-only solution; and the one using GPS, GLONASS, and Galileo observations together, is the GRE PPP solution. R is short for the Russian system GLONASS, and E is short for Europe system Galileo.
The GNSS data was collected by a GNSS receiver on R/V Lance. It is used by the Norwegian Polar Institute (NPI) for regular monitoring and research related to ocean and sea ice properties in Fram Strait. During the Fram Strait 2016 cruise from day-of-year (DOY) 238 to DOY 257, a geodetic JAVAD TR_G3TH GNSS receiver was installed on the ship bow, which is about 6 m above the water surface. This receiver collected multi-GNSS data at a sampling of 1-Hz, including GPS, GLONASS, and Galileo.
