From: Experimental verification of seafloor crustal deformation observations by UAV-based GNSS-A

Obtained seafloor position time series. Eastwards, northwards, and upwards components are shown in order from the top. Black and red circles indicate results obtained by vessel-based GNSS-A using dual-frequency GNSS and UAV-based GNSS-A using single-frequency GNSS, respectively. Position error bars indicate a width of ± 1 σ obtained in GARPOS.
