Atheras Analytics SAS has announced the release of its DESIRISS Ground Network Dimensioning tool, intended for satellite operators in the non-geostationary satellite (NGSO) sector. Developed within an ESA project supporting IRIS, DESIRISS provides a scalable approach for designing ground networks for large satellite constellations. The software helps operators evaluate system performance and optimize antenna distribution, reporting capital expenditure savings between 30 and 45 percent.

DESIRISS simulates NGSO constellations operating at Ku-, Ka-, and Q/V-band. It uses artificial intelligence and historical weather records to predict rain attenuation for each operation band. Features include propagation modeling, inter-satellite link analysis, terrestrial network optimization, and multi-ob
