ISS & Satellite Tracker vs 少年SSTV地面站

Orbit turns your iPhone and iPad into a real-time satellite tracker. Raise your camera toward the sky and watch satellites, planets, constellation lines, and debris appear through augmented reality. Browse a catalog of 15,000+ objects, get descriptions of any spacecraft, and never miss an ISS pass. SKY VIEW Point your phone at any part of the sky. Orbit overlays live satellite positions, planets, and constellation lines directly onto your camera. The ISS and Tiangong space station pulse with a live indicator so you never miss a crewed spacecraft. Edge arrows guide you toward objects just outside the frame. OVERHEAD See the closest satellites in real time, ranked by altitude. Each card shows orbital speed, altitude, and next visible pass time. Tap any satellite for full orbital data, upcoming passes, and an AI-generated description. AI DESCRIPTIONS Every satellite has an on-demand description powered by Gemini AI. Ask Orbit about any spacecraft's mission, operator, or history, right from the sky view or catalog detail page. PASS PREDICTIONS Never miss the ISS again. Orbit calculates upcoming visible passes for objects near you: start time, peak elevation, and direction. Step outside at exactly the right moment. CATALOG Browse 15,000+ active satellites, space stations, weather platforms, navigation constellations, and debris. Filter by category or country of origin. Search by name or NORAD ID. Sort by altitude, inclination, or launch date. MUSEUM Explore historically significant missions, from Sputnik 1 to the Hubble Space Telescope. SPACE EVENTS Curated upcoming launches, milestones, and astronomical events, updated regularly. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
