GPS IIR-20 (IIRM-7) is SVN 49 (PRN 1) in slot B2, replacing PRN 30. Mass 2059 kg at launch.
SVN 49 carries the first L5 payload for civil signals, to reserve the band for the later IIF satellites ahead of an ITU deadline. The payload caused interference with the main L1 and L2 signals and this led to the satellite's early retirement in 2011.
