Beidou 6

 2009-018A


On Apr 14 China launched the second "second generation" ('erdai') Beidou navigation satellite, COMPASS-G2 or 'er ke Beidou Daohang Weixing' using the CZ-3C (Chang Zheng sanhao bing) launch vehicle. The satellite was initially placed in geostationary transfer orbit; by Apr 29 it was apparently station in geostationary orbit, with no intermediate tracking available. However, the satellite appears never to have made stationkeeping maneuvers and slowly drifted off station. On 2010 Sep 8 its orbital period was adjusted to move it further out of synchroncity.

The first four Beidou were called 'Beidou Daohang Shiyan Weixing', or Beidou Navigation Test Satellite; the most recent two are the operational 'Beidou Daohang Weixing'.

Navstar 49

 2009-014A


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.
