龙江三号试验卫星发射成功Quote
At 10:35 today, the Kuaizhou-1A solid carrier rocket was ignited and lifted off at the Jiuquan Satellite Launch Center, sending my country's first flat-panel new system communication test satellite "Longjiang-3" to the It entered the predetermined orbit, and the launch mission was a complete success. This mission is the 20th launch of the Kuaizhou-1A solid carrier rocket.
The payload is Longjiang-3 (龙江三号). -

Longjiang-3 is prototype communication satellite by the Harbin Institute of Technology (HIT), to test a new satellite platform "in the shape of a plate" (you know, like that constellation that starts with an "S") for future LEO high speed communication satellite constellations uses.

龙江三号试验卫星发射成功
At least mystery solved regarding the payload carried to orbit by today's Kuaizhou-1A launch, given that you earlier considered the Weli Kongjian Yihao Xitong (微厘空间一号系统) to be the possible payload.QuoteAt 10:35 today, the Kuaizhou-1A solid carrier rocket was ignited and lifted off at the Jiuquan Satellite Launch Center, sending my country's first flat-panel new system communication test satellite "Longjiang-3" to the It entered the predetermined orbit, and the launch mission was a complete success.

Longjiang-3 cataloged in a 490 x 500 km x 49.1 deg orbit. The KZ-1A 4th stage made a perigee lowering burn to a 132 x 557 km orbit and will make an uncontrolled reentry in a few days
