Satellite Constellations - launches vs time

Constellation Launch History

This plot shows the satellites launched vs time.

Note: The categories in this plot are assigned using a heuristic based on the orbital data. They do not always exactly agree with the categories used in the "today's constellation statisics" tables, but the totals are usually close.

Note: The letters are those used in byte 8 of the SatType code in the GCAT satellite catalog entries.
