What is LEOS: First Orbit?

LEOS: First Orbit is the public gateway into our simulation ecosystem, a completely free, browser-based space environment that brings satellite operations to life for anyone, anywhere. Built for accessibility and powered by real physics, First Orbit transforms your desktop into a live orbital operations center.

Whether you’re a student, educator, enthusiast, or future mission planner, First Orbit delivers a mission-grade simulation experience with:

  • Real-time satellite tracking of CRTS-1, Bulldog, and 12,000+ live space assets

  • High-fidelity orbital mechanics powered by SGP4 propagation models

  • Interactive Earth with orbital trails, lighting, and Starfield background

  • Realistic telemetry panels, ground station integration, and SDA tools

Learn with Precision, Every Detail Mirrors Real Space Operations

LEOS: First Orbit isn’t artistic guesswork or game-like approximation. It’s powered by real orbital physics and propagation models used across the industry, including SGP4 and SDP4.

Every satellite orbit, every positional update, every orbital path is grounded in true-to-life data, calculated and rendered in real time.

LEOS reflects how real satellites operate in space: how they move, respond to Earth’s gravity, and maintain orbit. It’s not a simulation built to entertain, it’s built to inform, train, and inspire accuracy from the start.

Comprehensive Infrastructure for Total Mission Insight, Not Just Software

LEOS: First Orbit delivers more than orbital graphics. It creates a real-time, data-driven space operations environment built for professionals, students, and mission planners alike.

What you see is grounded in operational accuracy, real satellites, real orbital physics, real telemetry, streamed and visualized through an engine designed for mission-grade fidelity. From line-of-sight tracking to dynamic telemetry displays, LEOS prepares users to think like operators, not just observers.

Whether you’re in a classroom or a command center, First Orbit transforms any system into a launchpad for understanding space as it truly operates.

LEOS in Action

Satellite Tracking in Motion

Follow CRTS-1 and Bulldog as they orbit Earth in real time. Watch their position update every second based on real-world orbital mechanics, giving you a true sense of motion and scale in Low Earth Orbit.

Mission Dashboard Preview

Get a first look at LEOS’s mission dashboard, where telemetry and orbital data are displayed as satellites traverse the simulated environment. While control functions are coming soon, this version gives you visibility into how real-time data flows through the system.

3D Earth Environment

Immerse yourself in a fully interactive 3D Earth with cloud layers and a moon. Zoom, pan, and rotate the view to observe the satellites from any angle—built for clarity, engagement, and realism.
