Abstract : Locations of Doppler satellite observing stations were revised to obtain a set which is more self-consistent and more consistent with the CIO pole. Residuals of satellite observations for 1970 were analyzed using the new coordinates to determine mean and standard errors for five days of observations of components of station position versus station, time of day; and elevation angle. The accuracy of the determination of a component of station position is about 4 meters at moderate and high elevation angles. But since more satellite passes occur at lower elevation angles, the accuracy of determination of a component of position based on five days of observation of one satellite is only about 2 meters.
