aweglteo/aerie

A software framework for modeling spacecraft.

Aerie is a software framework for modeling spacecraft. Its main features include:

• A Java-based mission modeling library
• A discrete-event simulator
• An embedded TypeScript DSL for defining and executing scheduling goals
• An embedded TypeScript DSL for defining and executing constraints
• An embedded TypeScript DSL for defining and executing activity command expansions
• An embedded TypeScript DSL for defining sequences
• A GraphQL API
• A web-based client application

Getting Started

To get started using Aerie for the first time please do our fast track tutorial on our documentation website.
