A demonstration of differenced dual-station one-way doppler conducted with Pioneer 11

Simultaneous one way Doppler demonstrations performed on Pioneer 11 are described. The data noise of the differenced one way doppler as computed from the pseudo residuals is around 0.002 Hz, which is nearly an order of magnitude smaller than the one way Doppler noise and about the same as differenced two way/three way Doppler noise. The demonstration results and the applicability of differenced one way radio metric data to spacecraft navigation are discussed.
