The speed of light is variant. Light speed for the receiver (Earth) is not constant. There is also the vector radiation of light and energy which does not conform to the simple model of Relativity. NASA and space agencies used a fixed Earth (ECI or Earth Centred Inertial) in their software and calculations for satellites, probes and instrumentation. They don’t use ‘heliocentricity’.

Questions about Global Positioing Systems (GPS) or geo-synchronous satellites are an example. Neither proves the Earth’s alleged Copernican motion, nor Einsteinian Relativity. Quite the opposite. They highlight the issues with Newtonian and Einsteinian physics. More here
