Satcat

Satcat by Kayhan Space brings the Satcat satellite catalog into ChatGPT. Find satellites by name, NORAD ID, international designator, owner, country, mission or orbital parameters. Retrieve latest or historical TLEs, compare two to four satellites, plot orbital-element history, and show selected satellites or filtered groups on an interactive 3D globe. Chart the separation and radial, in-track and cross-track (RIC) components between satellites, track GEO longitude history and neighbors, find satellites in similar or shared orbital planes, and predict geometric ground passes for observer coordinates you provide. Find when satellites can be seen from one or more locations: passes above an elevation mask, and times when the site is dark while the satellite is sunlit, optionally filtered by weather.

Satcat is built for satellite operators, space situational awareness analysts, researchers and students. A Satcat account is required: sign in when ChatGPT asks you to connect. Results come only from catalog data your account can access.

Limitations: results are sampled predictions from catalog TLEs. Satcat in ChatGPT does not perform conjunction screening or collision-risk assessment. Ground passes are geometric line-of-sight predictions and do not account for weather or optical visibility. Visibility analysis does not assess imaging, SAR or RF access. Catalog classifications do not establish nationality or military status. Large selections are paged or bounded, and truncation, stale TLEs and unavailable values are always reported.
