Counts come from our live satellite catalog, refreshed every 3 hours from CelesTrak. We match by name prefix — for example, “STARLINK” for Starlink and “GSAT” for Galileo. Decayed satellites are excluded. Planned size is the operator's announced fleet target, which is often well above currently launched.
