Reference

Four public records for EU space operators and the authorities that supervise them, and three tools that check your own operation against them: the NIS2 scope check, ground station passes and the orbit globe. Each answers one question below, and every figure carries its date and its source.

Published by 303 Overwatch A.S.B.L, a Luxembourg non-profit, from public sources only, so that operators can find their own country, sites and assets and regulators can check our figures.

The counts and dates below are read from each record and tool when this page is published, so each one matches what that page shows today.
