Autonomous Trajectory Optimization
This application area focuses on automatically designing and executing optimal spacecraft trajectories and maneuvers—across single vehicles and swarms—under tight constraints on fuel, safety, and computation. It covers tasks like multi-phase interplanetary transfers, low‑Earth orbit transfers, constellation deployment, formation flying, collision avoidance, and close‑proximity operations such as inspection. Instead of relying on manual, expert‑driven analysis and slow numerical solvers, trajectory and control solutions are generated or refined automatically, often in (near) real time and at large operational scales. AI and advanced optimization are used to approximate complex dynamics, search huge maneuver spaces, and coordinate multiple spacecraft under uncertainty and communication limits. Techniques such as reinforcement learning, neural surrogates, and distributed model predictive control drastically cut computation time while maintaining or improving fuel efficiency and safety. This enables more agile mission design, real‑time onboard decision‑making, and economically viable operation of large satellite constellations and inspection vehicles.
The Problem
“Autonomous trajectory optimization for spacecraft maneuvering, coordination, and real-time control”
Organizations face these key challenges:
High dependence on scarce astrodynamics and controls experts
Slow numerical optimization for multi-phase and multi-vehicle problems
Difficulty handling uncertainty, model mismatch, and changing flight conditions
Poor scalability of centralized planning for large constellations and swarms
Limited onboard compute for real-time optimization and control
Fragmented toolchains across simulation, optimization, validation, and operations
Conservative safety margins that increase fuel burn and reduce mission flexibility
Complex certification and trust requirements for autonomous maneuver decisions
Impact When Solved
The Shift
Human Does
- •Manually design initial trajectories, phases, and maneuvers for missions using domain expertise and toolkits.
- •Tune solver parameters, constraints, and objective functions; run and rerun heavy numerical optimizations.
- •Review candidate trajectories for safety, fuel usage, and policy constraints, then select and approve final plans.
- •Manually design and validate formation‑keeping and collision‑avoidance maneuvers for constellations and swarms.
Automation
- •Run traditional optimization solvers (e.g., nonlinear programming, shooting methods) as configured by humans.
- •Provide basic simulation, visualization, and what‑if analysis tools without autonomous decision‑making.
- •Generate alerts for conjunctions or violations based on catalog data and simple rule‑based thresholds.
Human Does
- •Define mission objectives, constraints, safety policies, and acceptable risk/fuel trade‑offs at a high level.
- •Review and approve AI‑proposed trajectories and control policies, focusing on edge cases and mission‑critical segments.
- •Handle exceptions, policy updates, and strategic replanning when mission goals or external conditions fundamentally change.
AI Handles
- •Generate and refine trajectories (e.g., interplanetary transfers, LEO transfers, constellation deployments) using learned surrogates, reinforcement learning, and fast optimizers.
- •Continuously reoptimize and coordinate maneuvers for swarms and constellations using distributed model predictive control, subject to fuel and safety constraints.
- •Perform autonomous close‑proximity operations (inspection, rendezvous, formation reconfiguration) with minimal delta‑v, obeying keep‑out zones and collision‑avoidance constraints.
- •Run on‑board real‑time decision‑making: evaluate environmental changes, conjunction alerts, and actuator limitations, then update control actions without ground in the loop.

Real-World Use Cases
Automated naval gun targeting assistance for maritime surface threats
AI software helps a ship keep its guns aimed at a moving target on the water while the ship itself is also moving.
Robust multiple-model predictive control for aerospace vehicle ascent trajectory tracking
An onboard controller uses several flight models and keeps predicting the next moments of flight so it can choose control actions that keep a launch or ascent vehicle on its planned path even when conditions change.
Extensible astrodynamics workflow automation via Python API and plugins
Instead of doing everything by hand, engineers can script trajectory studies and add their own custom methods to the software.
