From what I gather from CCTV the main paylod was Jilin-1 (03). I think that's strange since Jilin-1 (01) was launched on a CZ-2D and there does not seem to be a  Jilin-1 (02). Plus Jilin-1 (01) seemd too heavy to be launched on a KZ-1A.
Any idea on what Jilin-1 (03) really is? Gunter's space page has is as http://space.skyrocket.de/doc_sdat/lingqiao.htm

From the Users Guide, the N2O4/MMH bipropellant fourth stage "Propulsion Control Module" appears to perform an initial separation burn from the third stage, followed by a several minute coast and, finally, a 5 to 6 minute long insertion burn for 700 km SSO missions.  At 0.4 g maximum acceleration, I would guess that the propulsion system provides 100 to 200 kgf thrust.  The module also appears to provide pitch/yaw/roll control during Stage 2 and 3 phases, including coast.

Any information on the solid motor stage thrusts?

try page 17 Table 2.1 in the L2 posted KZ1A UG
That chart gives "Impulse" in "Newton-seconds per Kilogram".  This should be specific impulse when divided by 9.81 m/sec^2 rather than thrust in Newtons.  Or am I off-base?

There were 4 satellites in the October 2015 launch. 2 of the 3 secondary payloads (not the main sat) are for video shooting with 1.3 m resolution. The main satellite on this flight follows these 2.

Kuaizhou series are for commercial launches, the cost of which is over 20000 USD per kilo now with KZ-1A.

CASIC aims to bring the cost down to 10000USD/kg with KZ-11 of which the maiden flight is expected end of this year.

By 2025 and with KZ-21, the cost per kilo will see a further cut to 1000 USD.

CASIC's ultimate goal is a few hundreds USD per kilo.
