Meridian 1(Russian:Меридиан-1), also known asMeridian No.11L,was a Russiancommunications satellite.It was the first satellite to be launched as part of theMeridiansystem to replace the olderMolniyaseries.
Meridian 1 was the first Russian Government satellite to be launched by aSoyuz-2rocket. The Soyuz-2.1a configuration was used, along with aFregatupper stage. The launch occurred fromSite 43/4at thePlesetsk Cosmodromeat 08:34:44 GMT on 24 December 2006.[1]
It was constructed byISS Reshetnev(at the time known as NPO-PM) and was believed to be based on theUragan-Msatellite bus,[2]which has also been used forGLONASSnavigation satellites.It operated in aMolniya orbitwith aperigeeof 900 kilometres (560 mi), anapogeeof 39,000 kilometres (24,000 mi), and 65°inclination.[2]
The satellite entered service on 1 February 2007. By May 2009 it had failed, before the end of its projected lifespan. NPO-PM reported that an impact with a piece of debris had caused the spacecraft to malfunction.[3]
Meridian 1re-enteredon 6 July 2021, around 12:20UTC.[4][5]
