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.

 

 

Connect with NRAO

The National Radio Astronomy Observatory and Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
