Rocket launch capability is the basic support and main constraint of satellite constellation networking, which directly determines the scale, cost and progress of constellation construction.<\/p>\n
Currently, StarNet has launched a total of 4 batches of network stars. Long March 5B launched twice, carrying 10 stars each time; Long March 8A launched once, carrying 9 stars at a time; Long March 6A launched once, carrying 5 stars at a time.<\/p>\n
Next, we will briefly review the various parameters of the Long March 5B, Long March 8A, and Long March 6A.<\/p>\n

When performing the Starnet mission, Long March 5B is equipped with the Yuanzheng 2 upper stage. Yuanzheng-2 is my country\u2019s liquid-powered upper stage with the largest carrying capacity and strongest orbit-changing capability. Yuanzheng 2 is equipped with a YF-51D engine, which is composed of two YF-50D engines in parallel, with a total vacuum thrust of 13 kN. The propellant of YF-50D is dinitrogen tetroxide\/uniform dimethyl hydrazine, with a vacuum thrust of 6500 N and a vacuum specific impulse of 3099 m\/s.<\/p>\n
