An Intelligent Digital Observatory
Project Zenith transforms passive observers into active explorers of the dynamic sky — combining authoritative telemetry, scientific astronomy and AI-generated insight.
Real-Time Telemetry
Live ISS position from Open-Notify, active-satellite TLEs from CelesTrak, and weather from Open-Meteo.
Predictive Simulation
SGP4 propagation and Skyfield/Astropy compute future satellite and planetary positions across time.
AI Cosmic Narrator
Complex telemetry translated into plain-language, location-aware explanations of your sky.
Observation Readiness
A dynamic score blends cloud cover, lunar interference, light pollution and visibility.
Zenith-Focused View
A transparent observation cone projected through your local East-North-Up reference frame.
