China's 1st ever amateur radio satelite XW-1 is in space now!
AMSAT China reports it was launched at about around 0230 UTC on
December 15, 2009. The beacon was received in Sanya after launch.
XW-1 was a secondary payload aboard the CZ-4C rocket from Taiyuan
Satellite Launch Center into a sun-synchronous orbit about 1200
kilometers high. The primary payload of this launch is the Yaogen-8
Remote Sensing Satellite.
The preliminary keplerian elements for the satellite are:
1 99999U 09349.11987269 .00000000 00000-0 00000-0 0 00006

The XW-1 communications payload includes a beacon and three cross
band transponders operating in FM, linear, and digital modes.
