1. Purpose

The purpose of this document is to establish the planned development strategy for the ASTRA Autonomous Flight System.

This roadmap defines the engineering phases, major milestones, dependencies, expected deliverables, and success criteria that will guide development throughout the project lifecycle.

This document serves as the baseline planning document for the ASTRA program and may evolve as new requirements, technical discoveries, and project priorities emerge.

2. Development Philosophy

ASTRA follows an iterative systems engineering approach.

Each subsystem progresses through the following lifecycle:

Concept
Requirements
Research
Trade Study
Architecture
Design
Implementation
Simulation
Testing
Verification
Validation
Integration
