Notes. The year in the Constellation column refers to the period during which that model was launched. M1000 km refers to the apparent magnitude normalized to a distance of 1000 km between the observer and the satellite; for some references, the dispersion is estimated over normalized magnitudes while for others it is estimated over measured magnitudes; a is the typical altitude of the satellites in the constellation, when in operation; Ma is the apparent magnitude of a satellite at zenith, derived from M1000 km.
