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…
