8 Jun 2023: China launched a Kuaizhou-1A solid rocket lifted off from a TEL at the Jiuquan Satellite Launch Center. The China Aerospace Science and Industry Corporation (CASIC) confirmed launch success a short time later. Aboard the flight was the Longjiang-3 experimental stackable communications satellite, jointly developed by a commercial satellite company and its parent entity, the Harbin Institute of Technology (HIT), in Northeast China. Launch Video.

Longjiang-3 has been cataloged in a 490 x 500 km x 49.1 deg orbit. The satellite will test communication technologies including signal regeneration and network slicing, and provide technical support for China’s satellite Internet construction.

– HITSat was established in December 2020 and is developing a number of small satellite platforms. The SATware-CS200 Ka-band satellite platform, on which Longjiang-3 is based, is capable of downlink speeds of 600 Mbps and 500 Mbps uplink.

– The platform is designed for mass production, automatic assembly and stacked launches. The configuration makes it similar to SpaceX Starlink satellites.

-Separately, private firm GalaxySpace is expected to launch its first flat panel satellites with flexible solar arrays in the second half of 2023. The country has in recent years greatly increased its small sat production capabilities.

-China is currently developing plans to build its own low Earth orbit satellite megaconstellation that would provide its own answer to Starlink. It would provide satellite internet infrastructure for China and potentially rival Starlink and other systems, while also positioning China as a provider of global infrastructure.

– Known as “Guowang,” or national network, the constellation is expected to eventually consist of 13,000 satellites, according to filings with the ITU. It is not known if HITSat will be involved in the project. Watch Guowang background Video.

-China is at the same time looking to boost its launch capacity to get its Guowang satellites into orbit. Measures being taken include adapting the Long March 5B to use an upper stage to insert numerous satellites into orbit, ramping up production of the expendable Long March 8, and possibly leveraging the emerging commercial launch sector.
