But that would be a clear violation of causality - even if you tried to support this proposition by proposing quantum entanglement using the Bohm Interpretation of quantum mechanics as the method of communication between the traveller in the past and the satellites in the future, the fact that causality is preserved in quantum mechanics is a rigorous result in modern quantum field theories, which makes that supposition non-viable.
