Reliable TT&C during superior solar conjunctions

The purpose of this study was to define the a communication subsystem architecture (including both ground and space segments, as well as operational methods) that allows robust RF TT&C links during superior solar conjunction phases. The defined architecture shall ensure robust and reliable links in scintillation regimes (i.e. at low SEP angles) where TT&C links are nowadays degraded, leading to occasional link interruptions. Similarly, the defined architecture shall ensure that at even higher scintillation regimes (i.e.

Reliable TT&C during superior solar conjunctions

The study aims at investigating technical solutions to design a reliable TT&C system during superior solar conjunctions, to mitigate the detrimental effects of phase and amplitude scintillation, which limit the maneuvers under 5 deg of Sun- Earth-Probe (SEP) angle. After the analysis of data acquired during superior solar conjunctions of Mars Express (MEX) in 2013-2015 and Cassini in 2001-2002, that allowed deriving a mathematical model to be used in the simulations, the current ESA TT&C system has been evaluated, in terms of link performance.
