Planetary Radio Interferometry and Doppler Experiments (PRIDE): a multidisciplinary enhancement of space science missions
Abstract
The Planetary Radio Interferometry and Doppler Experiments (PRIDE) project led by the Joint Institute for VLBI in Europe (JIVE, Dwingeloo, The Netherlands) is designed as a multi-purpose, multidisciplinary 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 radial Doppler measurements and phase-referenced Very Long Baseline Interferometry (VLBI) tracking. 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, I will describe the principles of PRIDE data collection, processing, and analysis and present demonstration results of a recent observing campaign conducted with ESA's Mars Express spacecraft.
