The Global Navigation Satellite System (GNSS) real-time kinematics (RTK) is a technology to provide centimeter-level navigation services in outdoor areas.GNSS/INS integration Oven Door Spring is a typical integrated navigation system, including loosely, tightly, and ultra-tightly coupled integration, which has been studied for decades.Although GNSS
ABSTRACT Soil saturated hydraulic conductivity (Ksat) and steady-state infiltration rate (SSIR) are essential and necessary soil properties for different geoscience applications.Values of these hydraulic properties for the Brazilian territory are difficult to access and are dispersed in research efforts carried out around the country.This study dev
