Determination of Plate Tectonic Motion from Doppler Observations of Navy Navigation Satellites.
Abstract
Doppler observations of Navy Navigation Satellites have yielded precisions in the determination of rates of change of station position of 2 cm/yr, based on data sampled over a 14-yr period, and 3 cm/yr for nearly continuous data over a 6-yr period. The accuracy of the determination is better than 10 cm/yr in horizontal position and 15 cm/yr in height for either data span. A number of changes in data acquisition and data reduction are proposed which will improve the accuracy of the results and lead to the determination of plate tectonic motion from this data. The computed latitude rate for Australia, which is 12.1 + or - 1.5 cm/yr, is consistent with geologic estimates. Maintenance of the base station network is critical to obtaining such results for other components of station position, other geographic areas, and other time periods. (Author)
