N2yo tools 3
get_positionsTrack where a satellite is right now (or in the next few seconds): get its live latitude, longitude, altitude, and look-angles (azimuth/elevation) from an observer on Earth. Use this to answer "where is the ISS right now?" (NORAD id 25544) or to locate any satellite by NORAD id. Example: get_positions({ norad_id: 25544, lat: 40.71, lon: -74.0 }).get_visual_passesFind when a satellite will be visible to the naked eye overhead from an observer location (visual passes = bright, sunlit passes against a dark sky). Returns start/max/end times, elevation, azimuths, brightness magnitude, and duration. Use this for "when can I see the ISS pass over?" Example: get_visual_passes({ norad_id: 25544, lat: 40.71, lon: -74.0 }).whats_aboveList what satellites are currently above a location on Earth, within a given radius of the observer's zenith. Use this to answer "what satellites are overhead right now?" Optionally filter by category (e.g. 52 = Starlink, 18 = amateur radio, 1 = brightest). Example: whats_above({ lat: 40.71, lon: -74.0 }).
