OrbitPulse

Decode orbits, track satellites, and plan radio sessions with OrbitPulse, a practical reference tool for amateur radio operators and satellite tracking enthusiasts. Get essential orbital calculations, satellite data, and communication references in one place, ready to use during a pass. Decode any TLE set with a single tap and explore inclination, eccentricity, perigee and apogee altitude, orbital velocity, mean motion, B* drag parameter, and orbit type, including LEO, MEO, GEO, SSO, HEO, and Molniya orbits. Browse a live catalog of amateur satellites from CelesTrak, search by name or NORAD number, and check known receive and transmit frequencies and modulation modes for active satellites. Calculate circular orbit parameters, Hohmann transfer ΔV budgets, and radio link budgets, including free-space path loss and maximum Doppler shift. Use ready-made settings for the ISS, GPS, and geostationary orbit scenarios. Bookmark satellites for quick access during passes and keep your selected objects available between sessions. Explore the built-in reference covering TLE fields, orbit types, amateur VHF/UHF/L/S-band frequency tables, and unit converters for degrees, radians, mean motion, and orbital period. From your first CubeSat pass to planning a transfer toward geostationary orbit, OrbitPulse puts the essential tools for satellite tracking and amateur radio in your pocket.
