Venus Express radio occultation observed by PRIDE
T. M. Bocanegra-Bahamon, G. Molera Calves, L. I. Gurvits +18
Context. Radio occultation is a technique used to study planetary atmospheres by means of the refraction and absorption of a spacecraft carrier signal through the atmosphere of the…
Planetary Radio Interferometry and Doppler Experiment (PRIDE) Technique: a Test Case of the Mars Express Phobos Fly-by. 2. Doppler tracking: Formulation of observed and computed values, and noise budget
T. M. Bocanegra-Bahamón, G. Molera Calves, L. I. Gurvits +5
Context. Closed-loop Doppler data obtained by deep space tracking networks (e.g., NASA's DSN and ESA's Estrack) are routinely used for navigation and science applications. By "shad…
RadioAstron gravitational redshift experiment: status update
D. A. Litvinov, U. Bach, N. Bartel +25
A test of a cornerstone of general relativity, the gravitational redshift effect, is currently being conducted with the RadioAstron spacecraft, which is on a highly eccentric orbit…
RadioAstron as a target and as an instrument: Enhancing the Space VLBI mission's scientific output
Dmitry A. Duev, Mikhail V. Zakhvatkin, Victor A. Stepanyants +5
The accuracy of orbit determination has a strong impact on the scientific output of the Space VLBI mission RadioAstron. The aim of this work is to improve the RadioAstron orbit rec…
Spacecraft VLBI and Doppler tracking: algorithms and implementation
Dmitry A. Duev, Guifre Molera Calves, Sergei V. Pogrebenko +3
We present the results of several multi-station Very Long Baseline Interferometry (VLBI) experiments conducted with the ESA spacecraft Venus Express as a target. To determine the t…
