Preliminary GNSS-R Altimetry in the Hudson Bay Based on Spire Grazing Angle Measurements
peer reviewed This paper presents high-precision phase altimetric retrievals using the GNSS reflected signals off of sea-ice under grazing angle geometries collected by the Spire Global, Inc. satel-lite constellation. The region and period selected for this study (Hudson Bay and James Bay from Janua...
