Kayhan Space unveils GPU-accelerated satellite propagator sgp4.gl

Questions and Answers: 

Q: What is sgp4.gl? sgp4.gl is a GPU-accelerated SGP4 orbital propagator that enables real-time satellite visualization at catalog scale directly in a web browser.

Q: Who can use sgp4.gl? A: The software is free and open-source, available to developers, satellite operators, and researchers interested in large-scale satellite modeling.

Q: How does sgp4.gl improve performance over traditional methods? A: It leverages GPU acceleration to maintain high frame rates when processing thousands of satellites, ensuring smooth interactions and better visualization.

DENVER - Kayhan Space, a provider of advanced spaceflight intelligence and autonomous safety solutions in Boulder, Colo., announced the launch of sgp4.gl, a GPU-accelerated SGP4 propagator designed for large-scale satellite modeling. The tool enables smooth, real-time propagation directly in the browser, allowing high-fidelity visualization of thousands of satellites simultaneously.

Kayhan says that traditional orbital propagation methods often struggle to scale with large satellite catalogs, resulting in low frame rates and degraded user experience. sgp4.gl overcomes these limitations by using GPU acceleration to maintain performance even as orbital datasets grow.

"As a company, we have significantly benefited from using existing open-source technologies, and we're happy to give back to the community whenever possible," said Araz Feyzi, co-founder and CTO of Kayhan Space.

Open source

The software is freely available and comes with an open-source demo integrating sgp4.gl with Next.js and CesiumJS, deployable on Vercel. The demo allows developers and operators to explore, test, and extend the tool, processing tens of thousands of satellite tracks at once. A live version is available at https://sgp4gl-demo.vercel.app, with source code on GitHub.

"sgp4.gl is one way we are giving back to the community of developers and operators building the future of space," said Hyun Seo, chief product officer at Kayhan Space. "It is free, performs at a level that makes large catalogs easy to explore, and offers a glimpse of the advanced capabilities we are delivering in our production systems."
