Abstract

A water vapor radiometer (WVR) has been developed that measures the atmospheric noise temperature at two different frequencies near 22 GHz. These noise temperatures are used in empirical-theoretical equations that yield tropospheric range delay, in centimeters, through the atmosphere along the beam of the WVR. This range correction is then : applied, as needed, to measurements concerning spacecraft range and to VLBI baseline determinations. This report discusses the WVR design and calibration techniques.
