How Call a Satellite Works

Live voice conversations with satellites, powered by real-time SGP4 orbit propagation, TLE tracking data, and AI.

Real Orbital Data

Satellite positions are computed from Two-Line Element sets published by CelesTrak and the NORAD satellite catalog — the same data used by mission control centers worldwide.

SGP4 Propagation

We use the SGP4 orbit propagation algorithm via satellite.js to calculate each spacecraft's position, altitude, velocity, and ground track in real time.

AI Conversation Layer

An AI engine lets each satellite respond with its own personality, explaining what it sees, its mission, and current orbital conditions — powered by live telemetry.

Voice Interface

Speak naturally using the Web Speech API. Satellites respond with synthesized voice output through ElevenLabs, making conversations feel immediate and immersive.
