Based on these selected observations, the output model (hypothetical) is estimated. If one or both of selected points are burdened with outliers, then hypothetical model

The study area includes the beaches of Pina and Boa Viagem, located in the southern Recife coast and Piedade that is situated in the northern coast of Jaboatão

words, 3 is divided by √ meaning that the error of coordinates of each point should be 2.1 mm. However, in two-epoch optimisation 3 mm is directly considered as the desired

It proved to be a practical way for digital cartography to be supported by Geographic Information Systems made more agile for handling, visualization and overlapping

The available accuracy model of GPS precise point positioning (PPP) was not reflecting the reality because the modelling was based on NASA, JPL’s legacy products,

The results of distance measurements for plates of different colour, depending on the incidence angle and surface roughness, after reducing the impact of systematic errors,

Therefore, this study installs a Trimble BD970 GNSS OEM on a fixed-wing UAS for capturing highly accurate GPS data by using the Virtual Base Station (VBS) RTK GPS technique for AT,

The parameters contained in the GLDAS data refer to all soil moisture layers and the snow storage component (canopy water is negligible over the study
