Abstract
The Planetary Radio Interferometry and Doppler Experiment (PRIDE) is one of the eleven experiments of JUICE, ESA’s mission to explore the icy moons of Jupiter. It repurposes astronomical techniques to estimate the angular coordinates (VLBI) and relative velocity of the spacecraft, characterized through an unusual type of Doppler observable.
Using observations of the 2013 Phobos flyby of Mars Express, this project
presents the first successful application of PRIDE Doppler to scientific orbit estimation, and an original approach to the characterization of uncertainties exploiting the unique characteristics of this experiment.
