SPENVISbased

SPENVISbased is an adjective used to describe software, datasets, or analyses that are built upon or rely on the SPENVIS platform. SPENVIS stands for Space Environment Information System, a web-based toolkit maintained by the European space research community to access and compare space environment models and data. A SPENVISbased product typically integrates one or more SPENVIS radiation, plasma, or micrometeoroid models to characterize the space environment along a mission profile or to assess effects on spacecraft systems.

A SPENVISbased analysis may produce mission-specific outputs such as dose and linear energy transfer spectra, total ionizing dose, displacement damage, or single-event upset rates, often in the context of shielding design, satellite reliability analyses, or mission risk assessment. Because the SPENVIS platform provides standardized models and data with documented validity ranges, SPENVISbased results aim to be reproducible and traceable to the original SPENVIS components and version numbers.

Users configure SPENVISbased analyses by inputting mission parameters (orbit, duration, attitude), selecting relevant models, and exporting results for integration into design workflows. The term emphasizes that the methodological backbone comes from SPENVIS rather than from independently developed tools, and that outputs should be interpreted within the context of the SPENVIS model assumptions.

Limitations include dependence on the underlying SPENVIS models and data, potential lags in updating models, and the need to verify applicability to a given mission scenario. SPENVISbased work should cite SPENVIS versions and model choices. See also SPENVIS, space environment, radiation effects, mission design.
