Abstract
Communication systems aboard space launch vehicles, such as Ariane launchers, face significant challenges within confined environments like the Vehicle Equipment Bay (VEB). These areas are defined by dense metallic structures and complex geometries that lead to signal degradation due to shadowing and multipath interference. Reconfigurable Intelligent Surfaces (RIS) have emerged as a promising solution to address these issues by dynamically adjusting signal reflections and improving propagation in such environments. This study explores the application of RIS in the VEB through numerical simulations, evaluating their potential to enhance communication capacity and reduce signal losses. By focusing on this particularly challenging environment, this work provides valuable insights into the benefits and limitations of RIS technology. The findings presented offer a new perspective on overcoming the obstacles faced by traditional wireless systems in confined, reflective environments.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
