JSatOrb is an ISAE-Supaero's software tool dedicated to orbital calculation and designed for pedagogical purposes, with professional level features outputs.
It has been initiated to find a soft which would fill the gap between local teachers developed tools and professional tools, exploiting state of the arts
algorithms concerning space mechanics calculus. Even if current provided open source libraries are not fully compliant with our pedagogical requirements (simplicity, flexibility, multi-plateform and ergonomics), they provide complete and accurate calculus methods that are dedicated to a professional use. However, GUI part is not the main concern when used by space engineers which only require API access.
Concretely, JSatorb project is open-source (MIT license) and under development. It is inspired from current full-stack implementation methods. Ergonomic and intuitivity are at stack concerning the front-end, which is mainly based on Angular (https://angular.io/) and Cesium (cesiumjs.org). Efficiency and correctness on calculus are provided by the back-end part, which relies on Orekit (https://www.orekit.org/). Developed in Java, Orekit is a space dynamics open source library. It depends only on the Java Standard Edition version 8 and Hipparchus (https://hipparchus.org/) version 1.0 libraries at runtime. It is widely used by ESA and CNES.
