Abstract
Simultaneous dual-frequency, round-trip (uplink and downlink) calibration of Doppler data is expected to be a requirement of several radio science experiments being planned for the next decade, and such (calibration) capability is expected to be achieved by the mid-1980s. Simultaneous dual-frequency, round-trip calibration would be straightforward except for the condition of unequal spacecraft turnaround ratios at S- and X-band. This article discusses the impact of unequal turnaround ratios on calibration accuracies in the specific cases of the Gravitational Wave Detection Experiment and the Solar Gravitational Quadrupole Moment Experiment.
