What is it about?
Scenario of future up-link arrays for space missions including error analysis, mainly about gravity distortion effect, and calibration issues. The key contribution is about the analytical expressions for the evaluation of gravity distortion on large reflector antennas and its impacto on the antenna performance.

Why is it important?
This is a cutting edge topic for future space comunication solutions and the work contribution helps in the fast and simply evaluation of the main impairments of future large antenna array for space communications.
Perspectives
This work is part of an ESA project that investigated the technical feasibility of future large antenna arrays for up-link in deep space missions. In additions to the targets and goals achieved, analysis methods are important for speeding-up the research and development processes. Thus, with simple and well validated methods that do not require large computation and that are not computational costly, it helps for the development of future systems.
