Call a Satellite lets you track and talk to satellites orbiting Earth. Pick a satellite from the live list — including the International Space Station — tap Call, and start speaking. The satellite responds with its own voice, describing what it sees, its current mission, and telemetry data in real time. FEATURES • Voice & Text Communication — Hold to speak using your microphone, or type a message. The satellite replies with synthesized speech and text. • Live Satellite Tracking — Watch the ISS move across a real-time map with ground track visualization. See altitude, velocity, and position update as you talk. • Real Telemetry — Altitude, velocity, latitude, and longitude are pulled from actual orbital data, not simulated. • ISS Pass Predictions — Get predictions for when the ISS will be visible from your location in the next 24 hours, with elevation and duration details. • Pass Notifications — Set alerts so you never miss a visible ISS flyover. • Multiple Satellites — Browse and call different spacecraft, each with its own mission profile. • Immersive Dark UI — Designed for stargazing. Pure black backgrounds, clean typography, and a mission-control aesthetic. Call a Satellite uses real orbital mechanics (SGP4 propagation) and live TLE data to track spacecraft. Voice input uses on-device speech recognition. Satellite responses are generated by AI. Built for space enthusiasts, amateur radio operators, students, and anyone who has ever looked up and wondered what it would be like to talk to something in orbit.
