Just a question: why China put one early-warning satellite on the top of australian and indonesia? Is there any US missile facility over there?

Maybe for monitoring Guam base and ship launched BMs from Pacific

Well done China. Now PRC's satellites cover virtually entire US, Europe, Central, South & West Asia, plus the Eastern Pacific theater. Way to go.

2011-08-19 00:10:28 China's experimental orbiter SJ-11-04, which was launched by a Long March II-C rocket Thursday, failed to enter the designated orbit due to a malfunction of the rocket.
Chinese orbiter fails to enter designated orbit due to rocket malfunction

http://defenceforumindia.com/forum/china/24536-china-s-third-launch-week-proves-too-much-long-march-2c-fails.html ---------the thread on DFI

--------------------------------
the comparable Launch Vehicles to PSLV in Long March family(CZ family--CZ1,CZ2 sercial,CZ3 serial,CZ4 serial) might be CZ-2 A,C,D(LongMarch 2 A,C,D or LM 2 A,C,D) ....note: CZ-2 E,F,F/G not included.

basicly CZ2 serial is a 2 stage rocket, PLSV has 4 stages(some model has Strap-On, so 4.5 stages)...

PSLV CA/PSLV/PSLV XL have a range of

LEO payload ability :2100-3800 Kg
SSO payload ability: 1100-1750 kg-- the main payload of PSLV
GTO payload ability: 1050-1440 kg-- not the main purpose of this LV ,but due the GSLV problem, PSLV is also used for such missions.

parallelly CZ2 A/C/D would provide such payload ability

LEO payload ability :1800-3100 Kg
SSO payload ability: 750-2000 kg
GTO payload ability: 1440 kg ------only one model :Z-2C (3) CPKM was designed for this orbit ,but I'm afraid the launch never happened

due to the limited liquid rocket ability (Vikas engine-- similar to and a TOT of the Viking engine of Ariane 4 )and lack of the rocket engine cluster design , PSLV chose the complicated 4 staged structure (2 liquid ,2 solid),which made the this LV a little inefficient.(GSLV MK1,2 has the same problem, even the MK3)
PSLV's lift-off weight is as high as 294 tons...and with similar payload ability,CZ-2 C/D has a lift-off mass of 192-232 tons...

BTW ,we would see the high thrust rocket engine cluster design on GSLV MK3 for the first time,which is known as L110 engine.
