PulseSat Satellite Tracker vs Satplex

Look up. Right now, hundreds of satellites are passing silently overhead: weather birds, GPS constellations, communications relays, scientific instruments, and debris. PulseSat shows you exactly where they are, in real time, with the same precision used by aerospace engineers. Track over 10,000 satellites From the iconic International Space Station to the latest commercial space launches, PulseSat gives you instant access to a continuously updated catalog of active satellites and tracked objects. Each one is plotted using live orbital data and the industry-standard SGP4 propagation model — the same algorithm used by NORAD and space agencies worldwide. Know when to look up PulseSat calculates passes over your exact location for the next 7 days. See rise time, set time, maximum elevation, azimuth, and duration at a glance. No guesswork. No cloud lookups. The math runs entirely on your device, so pass predictions work even when connectivity is limited. Live position, every second Open any satellite and watch its position update in real time on a beautiful 3D globe. The ground track shows the full orbital path so you can see where it's been and where it's headed. Altitude, speed, azimuth, elevation, and range from your location are all displayed and refresh continuously. Explore by category Satellites are organized into curated collections: Earth observation, weather, navigation, amateur radio, space stations, science missions, and more. Browse a category to see every satellite in it plotted on an interactive 3D globe at once. Tap any dot to see its 2-hour ground track and name; tap again to dive into the full detail view. Built for space enthusiasts and professionals alike Whether you're a backyard astronomer timing an ISS flyover, a radio amateur preparing for a pass, a student learning orbital mechanics, or simply someone who wants to understand what's flying above them — PulseSat gives you the tools to do it. Dark mode, by design PulseSat is built from the ground up for dark environments. Whether you're outside at night with your eyes adjusted to the dark, or just prefer a clean dark interface, PulseSat looks exactly right. Orbital data is sourced from live TLE feeds and updated regularly. Accuracy depends on the age of the TLE data for each object.

Satplex is a real-time 3D satellite tracking app covering more than 30,000 objects in Earth's orbit — active satellites, rocket bodies, and debris, all visualized live on an interactive 3D globe. WHAT'S IN ORBIT From GPS and weather satellites to the International Space Station, explore the full catalog of tracked orbital objects. Search by name, browse by category, or tap any object for details — launch date, country of origin, orbital parameters, and an AI-generated description. LIVE ORBITAL TRACKING Every object is propagated in real time using SGP4, the same orbital model used by aerospace agencies worldwide. Watch positions update live as objects move across the globe — not a static snapshot, but the sky as it actually is right now. 3D GLOBE VISUALIZATION Zoom, rotate, and navigate Earth's full orbital shell, from low Earth orbit out to geostationary. See exactly where everything sits relative to Earth and to each other. Whether you're a space enthusiast, student, researcher, or just curious what's flying overhead, Satplex puts the entire orbital catalog in your pocket.
