Abstract
Electrical path delay caused by atmospheric water vapor may be a limiting error source for geodetic measurements made with very long baseline interferometry. Direct measurement of atmospheric water vapor is necessary to obtain path delay correction required by the ORION project. A dual-channel water vapor radiometer is described which operates at frequencies near the 22-GHz water vapor line and is capable of collecting data that will permit calculation of path delay with 2-cm accuracy.
