Title: Planetary Radio Interferometry and Doppler Experiment (PRIDE) for Planetary Science

Abstract:
The Planetary Radio Interferometry and Doppler Experiment (PRIDE) led by the Joint Institute 
for VLBI in Europe (JIVE, Dwingeloo, The Netherlands) is designed as a multi-purpose, multi-
disciplinary enhancement of space missions science return. The essence of PRIDE lies in its 
ability to provide ultra-precise estimates of spacecraft state vectors based on phase-referenced 
Very Long Baseline Interferometry (VLBI) tracking and radial Doppler measurements. The 
observations are carried out by an array of ground-based radio telescopes. These 
measurements can be used for a variety of scientific applications, both fundamental and 
applied, including planetary science, ultra-precise celestial mechanics of planetary systems, 
gravimetry, spacecraft orbit determination, and fundamental physics.

In this presentation, we describe the principles of measurements, processing, and analysis of 
PRIDE data and present demonstration results of the latest observing campaigns conducted 
with several operational science missions.
