Abstract: | Geodetic positioning accuracies obtained from range, integrated Doppler and double differenced interferometric phase observations
from a constellation of twenty-four Global Positioning System satellites are presented. It is demonstrated that GPS range
and Doppler observations will provide sufficient accuracy for the estimation of geodetic coordinates. However the instability
of the receiver atomic oscillator will limit the usefulness of these observations in providing rapid first-order baseline
determination. Interferometric phase measurements twice differenced to eliminate clock error appear as an alternate procedure
for providing such accuracies. |
