LEO Constellation Boxscore beta

The broadband mega-constellation race, by the numbers. This page is under development — several data sources are still being wired up. Sky intensity is the average number of satellites above 20° elevation for a mid-latitude observer, recomputed monthly from historical orbital data.

Data notes: Sky intensity is computed monthly by propagating each constellation's historical orbital elements and counting satellites above a 20° elevation mask, averaged across observation windows and longitudes. Fleet and re-entry figures come from public catalog data. Internet presence reflects prefixes observed in public BGP routing tables — constellations without a public ASN show no routing data even where service exists. n/a means no data source yet, not zero.
