OrbitalGuard watches the space between satellites

Field notes

The product combines public orbital catalogs with SGP4 propagation, broad-phase filtering, and numerical refinement of relative distance. Its interface exposes time of closest approach, miss distance, relative velocity, source epoch, and data age rather than reducing each encounter to an opaque number. The page presents an ISS workflow in which a visitor searches for the object, reviews predicted approaches, adds it to a watchlist, and configures a risk threshold. It also cautions that the system does not replace qualified operational conjunction assessment.
