NASA-AMMOS/aerie

PlanDev 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

Aerie -> PlanDev Rebrand

This product was formerly known as Aerie and is now named PlanDev. While we've updated most documentation and external references, some legacy mentions of the old product name may remain as we complete the transition.

What to know:

• The planning product, including modeling, simulation, scheduling and constraint-checking, is now named PlanDev
• The sequencing product, including the sequence editor, workspaces, and actions, is now named SeqDev
• All features and functionality remain the same
• Currently, repository names, package names and other internal code references will retain their existing names, and deployment/migration procedures have not changed
• In a future release, our repository and/or package names may change. If so, this will be communicated to users via release notes and normal communication channels
