Key Challenges

Effective application of generative AI solutions to engineering problems needs domain-specific insight. This project required the integration of expertise from both ADSP as AI experts and satellite communications expert partners, working collaboratively to ensure rapid iteration and clear communication throughout.

Additionally, satellite communications present particularly high demands for precision -solutions must be both innovative and rigorous, as only fully accurate, verifiable results are able to be implemented. We took pride in not just pushing the boundaries of what generative AI can achieve, but in reliably delivering robust, real-world outcomes.

The three proof-of-concept generative AI outcomes resulted from this project:

💠 Novel Choke-Ring Antenna Design Optimisation: Neural networks were trained on programmatically generated datasets, encoding both the design and key performance metrics. These neural networks were used to generate novel results that would improve performance.
💠 Text-to-CAD Web App: A web application powered by large language models (LLMs) and OpenSCAD, enabling the rapid conversion of text-based specifications into accurate, parametric 3D models. The tool leverages Retrieval Augmented Generation to further enhance design sophistication.
💠 Fine-Tuned Stable Diffusion Model: Trained on a curated set of approximately 80 satellite images, this model generates and adapts satellite imagery, demonstrating strong learning capabilities and practical adaptability.

Key Benefits

Generative AI unlocks creativity and efficiency in satellite design by exploring unconventional design spaces, reducing repetitive engineering workflows and increasing the speed of design iteration. Key benefits demonstrated through this project include: 📡Improved Performance: Created using a variational autoencoder, the best performing antenna design achieved greater angular range in transmission and reception compared to the industry baseline, while maintaining acceptable cross-polarisation discrimination. Simulation results were validated by physical tests.

Rapid Iteration: 3D CAD designs that could previously take 2–3 working days were created in under 20 minutes.
🛡️Enhanced Reliability: Code execution rates for LLM-generated CAD models reached between 80–100%, rising to 95% with self-evaluation modules.

How we did it?

Over nine months, ADSP worked closely with satellite communications experts to explore how generative AI could be responsibly embedded into real-world engineering workflows. The project mapped both the opportunities and challenges of applying these technologies to SatCom design, laying the foundations for future adoption.
