Orbitergreatly

Orbitergreatly is a fictional open-source software platform described here as a hypothetical tool for orbital mechanics simulation and mission planning. It is designed to provide accessible tools for students, educators, and researchers to model satellite orbits, spaceflight trajectories, and constellation deployments.

The project aims to offer accurate physics, modular extensibility, and cross-platform accessibility. It supports gravitational models ranging from two-body dynamics and patched conics to more complex n-body simulations, as well as common perturbations and transfer techniques used in mission design.

Key features include a scenario editor, real-time 3D visualization, scripting interfaces with Python bindings, and an open API for plug-ins. The software provides data export options and collaboration-friendly workflows. It also includes models for atmospheric drag in low Earth orbit and solar radiation pressure for higher orbits, enabling users to explore a range of operational regimes.

Architecturally, Orbitergreatly emphasizes modular components such as a trajectory solver, a physics engine, user interface, and data input/output layers. The architecture is designed to support community extensions and interoperability with external tools. The project is distributed under an open-source license and employs versioned releases to manage development.

History and governance are described here as following an informal, merit-based contributor model with public issue tracking and transparent decision-making. The concept emerged in the early 2020s among spaceflight enthusiasts as an educational alternative to more specialized software, not intended for mission-critical use.

Reception and impact note that the hypothetical tool is praised for accessibility in classrooms and hobbyist communities, while it is recognized to simplify some professional analyses. Future directions include expanded perturbation models, larger-scale constellation simulations, and performance optimizations.
