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
“Autonomously plan and execute fuel-optimal, constraint-safe spacecraft trajectories”
Organizations face these key challenges:
Planning cycles take days/weeks and require scarce expert astrodynamics labor
Late-breaking constraints (conjunction alerts, thrust degradation) force costly replans
Swarm/formation maneuvers don’t scale due to combinatorial coordination complexity
Hard to validate safety constraints and robustness under uncertainty across many scenarios
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.

Quick Win
Constraint-Guarded Trajectory Solver Toolkit
Build a mission-analyst-focused service that generates feasible maneuver sequences using deterministic optimization (e.g., simplified burns, waypoint transfers, time windows) with explicit constraints on delta-v, keep-out zones, and schedule. This level targets rapid feasibility and repeatability for a narrow class of problems (e.g., LEO phasing, basic constellation deployment) and produces plans that operators can review and simulate. It is not fully autonomous; it is an optimization accelerator with guardrails.

Real-World Use Cases
Computationally Efficient Distributed Model Predictive Control of Satellite Swarms
This is like giving each satellite in a large flock its own smart autopilot that talks to its neighbors, so the whole flock flies in formation safely and efficiently—without needing one giant, slow central brain on the ground.
Neural Network-Based Optimization of LEO Transfers
This is like teaching an autopilot to instantly guess the best way to move a satellite from one low Earth orbit to another, instead of having engineers run heavy simulations every time. Once trained, the neural network behaves like an ultra-fast calculator that outputs near‑optimal transfer strategies in a fraction of a second.
Multi-Phase Spacecraft Trajectory Optimization via Transformer-Based Reinforcement Learning
This is like an autopilot for planning complex space missions. Instead of engineers manually trying thousands of possible flight paths, an AI learns how to string together many propulsion burns and gravity assists to find fuel‑efficient, fast routes through space.
Minimal Delta-v Autonomous Spacecraft Inspection Using Genetic Fuzzy-Driven Control
This is like an automatic drone pilot for spacecraft that can fly around another spacecraft to inspect it, while using as little fuel as possible. It combines a rule-based "if this then that" pilot (fuzzy control) with an evolutionary optimizer (genetic algorithm) that keeps tweaking those rules until the flight path is both safe and very fuel‑efficient.
