Gravitational redshift test of EEP with RA from near Earth to the distance of the Moon
N. V. Nunes, N. Bartel, A. Belonenko +8
The Einstein Equivalence Principle (EEP) is a cornerstone of general relativity and predicts the existence of gravitational redshift. We report on new results of measuring this shi…
High spectral resolution multi-tone Spacecraft Doppler tracking software: Algorithms and implementations
Guifré Molera Calvés, Sergei V. Pogrebenko, Jan F. Wagner +5
We present a software package for single-dish data processing of spacecraft signals observed with VLBI-equipped radio telescopes. The Spacecraft Doppler tracking (SDtracker) softwa…
The antenna phase center motion effect in high-accuracy spacecraft tracking experiments
D. A. Litvinov, N. V. Nunes, A. I. Filetkin +5
We present an improved model for the antenna phase center motion effect for high-gain mechanically steerable ground-based and spacecraft-mounted antennas that takes into account no…
The gravitational redshift monitored with RadioAstron from near Earth up to 350,000 km
N. V. Nunes, N. Bartel, M. F. Bietenholz +6
We report on our efforts to test the Einstein Equivalence Principle by measuring the gravitational redshift with the VLBI spacecraft RadioAstron, in an eccentric orbit around Earth…
