Multi-facility GNSS antenna calibration

Abstract Accurate antenna calibrations are a cornerstone of high-quality global navigation satellite systems (GNSS) positioning, time and frequency transfer, precise orbits, and troposphere estimates. The international GNSS service (IGS) antenna committee maintains antenna phase...

Obtaining Scintrex CG6 Gravimeter Scale Factors with an Uncertainty Below $${1\cdot 10}^{-5}$$ in the Zugspitze Gravimeter Calibration System

Abstract Transportable spring gravimeters have many applications besides exploration geophysics and potential field determination, such as time-lapse measurements in hydrology and volcanology. For maximum accuracy, the time-dependent scale factor of each gravimeter must be determ...
