Chinese satellite propulsion startup secures funding as country’s constellation projects grow

HELSINKI — A Chinese language satellite tv for pc electrical propulsion firm has secured multi-million yuan angel spherical financing amid a proliferation of Chinese language constellation plans.

Kongtian Dongli (“Aerospace propulsion”) was established in March 2022. The spherical was led by  Jinshajiang Hongyu and MiraclePlus, in line with Chinese language media experiences.

The corporate’s foremost merchandise are Corridor thrusters and microwave electrical propulsion techniques, with an on-orbit take a look at of the latter deliberate earlier than December this 12 months. 

Few entities are engaged in propulsion for small satellites in China, however the demand for such techniques is obvious. 

China has established a state-owned enterprise to handle a nationwide satellite tv for pc web constellation of as much as 13,000 satellites. China SatNet has been partaking with industrial corporations because it develops a blueprint for setting up the “Guowang” constellation. 

Notably, these and different small satellites will likely be required to have onboard propulsion to scale back the possibilities of collision and mitigate the difficulty of particles in low Earth orbit.

A “discover on selling the orderly improvement of small satellites” (Chinese language) issued in Might 2021 states that small satellites ought to be able to collision avoidance maneuvers, in addition to decreasing orbits following the tip of missions. State departments might take related “acceptable measures” if an organization doesn’t observe, report on, and deorbit its satellites.

Plenty of industrial actors, generally in partnership with state-owned teams, are additionally growing low Earth orbit constellations for communications, distant sensing, navigation enhancement and extra. 

The core of Kongtian Dongli’s personnel come from China’s state-owned house sector, lots of which have beforehand been engaged in home satellite tv for pc electrical propulsion analysis and improvement. The corporate can also be engaged within the improvement of ramjet engines for each army and civilian makes use of. 

China’s conventional house sector has demonstrated capabilities in ion propulsion, with the Shanghai Spaceflight Energy Equipment Institute, the Middle for Area Science and Utilized Analysis (CSSAR) underneath the Chinese language Academy of Sciences, and the Lanzhou Institute of Physics have all developed electrical propulsion techniques, a few of which at the moment are operational on the Chinese language house station.

Northwestern Polytechnical College, Beihang College and Tsinghua College are additionally engaged in analysis. 

Spacety, a Changsha-based small satellite tv for pc startup, has efficiently examined in orbit iodine thrusters developed by French startup ThrustMe, and has signed a Memorandum of Understanding with Italian propulsion agency T4i.

Spacety lately examined a xenon corridor thruster offered by the large state-owned enterprise China Electronics Expertise Group (CETC) on its Chaohu-1 artificial aperture radar (SAR) satellite tv for pc. Spacety is working with CETC’s thirty eighth institute to construct a 96-satellite “Tianxian” SAR constellation.

China has been looking for to foster a industrial sector with sustainable provide chains and ecosystems, together with launch, small satellites and downstream purposes. 

Electrical propulsion is one other space through which new capabilities and mass manufacturing are required to help nascent industrial house actions, with others similar to house situational consciousness (SSA) prone to see new entrants because the sector grows.
