XW-1 uppe i rymden

Nu har Kina fått upp sin första amatörradio satellit.

Bilden nedan (ursäkta skärpan) visar vilka fina DX möjligheter som den kan erbjuda enligt dom nyss publicerade kepler som finns tillgängliga.

Som synes så kommer den täcka en bra bit av NA när vi har den lite över horisonten.

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:

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