Abstract

Precision ranging between planetary bodies would provide valuable scientific information, including tests of fundamental physics. Current ranging techniques based on retroreflectors, however, are limited to the Earth- Moon distance due to an inverse fourth power scaling. We present methods for interplanetary distances based on paired one-way ranging, which scales with a more favorable inverse square power. Corrections for clock offset, frequency error, and the Doppler effect are shown. We present the results of tabletop experiments demonstrating sub-millimeter ranging accuracy.
