It is reported that the Zhongxing-3A satellite is a communication and broadcasting satellite developed by the Fifth Academy of China Aerospace Science and Technology Corporation, which can provide users with voice, data and other services.
The Long March-7 carrier rocket is a new generation of medium-sized high-orbit liquid launch vehicle on the mainland, with a total length of about 60 meters and a geosynchronous transfer orbit carrying capacity of up to 7 tons.
The rocket adopts a newly developed satellite bracket to further increase the longitudinal usable envelope space of the fairing, and the mission adaptability of the rocket is improved. The optical fiber inertial group was optimized to improve the measurement accuracy and anti-interference ability of the inertial group. Reliability enhancement measures have been implemented for booster, first-stage and second-stage engines and auxiliary power systems, which have improved the reliability of rocket flight. The rocket also simplifies the vertical hoisting scheme of the rocket, and the workflow of the launch site will be further optimized in the future.
