list_satellitesList the popular satellites (ISS, Tiangong, Hubble and a few others) with each one's orbit data freshness. This is not the full list: every other tool also accepts any NORAD catalog number, e.g. 25544.
find_passesList every upcoming pass of one satellite over a location in the next windowHours (default 48, up to 240), in time order. Each pass has rise/peak/set times (UTC, plus riseLocal etc. on the observer's clock), peak elevation, azimuths with compass words (direction), the range at t…
get_positionWhere a satellite is now, or at a given time: the point on Earth straight below it (latDeg, lonDeg, not where it is in your sky), its altitude, and whether it is sunlit, with url (its page on seeksat.com). A location is optional: it only sets the time zone for local times and fo…
next_visible_passConvenience shortcut: the next pass of one satellite from a location (looks windowHours ahead, default 72). Use this only when the user wants "the next pass". Set chart:true to also render that pass's sky chart in this same call. To compare upcoming passes, or find the best one…
get_pass_weatherCloud-cover forecast (Open-Meteo and MET Norway) and the chance of a clear view for a location at one time, such as a pass's peak. The forecast reaches about 7 to 16 days ahead. viewingProbability is the clear-sky chance (0-1), blended toward 0.5 the further ahead the time is, s…
get_pass_chartRender a polar sky chart (PNG) of a satellite's pass over a location: where to look, with the moon, planets and stars in their real positions. Returns JSON (the charted pass as a full pass row, the same as find_passes gives, and a one-line summary) and the image. A geostationary…
search_satellitesSearch the full satellite catalog (about 17,000 objects) by name, alias or NORAD number, best match first. Use it to turn a name like "SDO" or "NOAA 19" into a NORAD number for the other tools; names outside the popular list only resolve directly on an exact whole-name match. To…
get_radio_passRadio details for one pass of a satellite over a location: its known downlink (and uplink) frequencies, the Doppler swing, when to tune to what frequency (at 10 and 30 degrees up and closest approach), and a table (at most 40 evenly spaced rows) of time, azimuth, elevation, rang…
best_passFind the best upcoming pass(es) over a location, ranked by the rating seeksat.com shows ("what's the best pass tonight?"). Give `satellite` to rank that one satellite's passes. Omit it to scan: in visual mode (default) the popular satellites plus every satellite in CelesTrak's v…
whats_up_nowWhat is in the sky over a location right now, from every satellite in the catalog (about 17,000, active satellites plus CelesTrak's visual group; most debris is not in it). mode "visual" (default) lists sunlit satellites above minElevation while the sky is dark there (Sun more t…
identify_satellite"What was that moving light?" Given where and when a light was seen, lists the satellites that were sunlit, above the horizon and within `tolerance` degrees of that spot, best match first, from every satellite in the catalog (active satellites plus CelesTrak's visual group). Nee…
