Medium Earth Orbit (MEO) satellite constellations have revolutionized global communications, offering reduced latency and extensive coverage compared to traditional geo-stationary satellites. However, these systems are vulnerable to atmospheric conditions that can deteriorate signal quality and impact the service performance. This article aims to strategically plan a tool to facilitate the preprocessing of data acquired through an experimental propagation program with the O3b MEO satellites constellation. These measurements capture valuable insights into atmospheric phenomena, particularly the signal attenuation dependency with the azimuth and elevation - a critical aspect of this kind of satellite communication. The designed tool streamlines data processing and facilitates the extraction of attenuation-related information.
