CZ-6 launch vehicle
Blasted off at Taiyuan Satellite Launch Center
, Succeeded in sending 16 satellites, including Jilin-1 Gaofen-03D09 into the preset orbit,
Marking a complete success of the launch mission
All the 16 satellites launched are developed by Chang Guang Satellite Technology Co., Ltd., and the launch services are provided by China Great Wall Industry Corporation, CASC as the general contractor.
CZ-6 launch vehicle is a 3-stage liquid rocket with propellant at normal temperature developed by Shanghai Academy of Spaceflight Technology, with the capacity to launch different types of satellites with different orbit requirements, and can also launch single or multiple satellites at the same time. The carrying capacity at sun-synchronous orbit can reach to 1.0 tons (orbit altitude: 700km).
This mission carried 16 satellites, posing multiple challenges to the layout design, installation operation and separation plans of satellites. Given the numerous quantity of satellite-rocket machinery and electrical interfaces, in order to meet the requirements for multi-satellite layout and control ways, CZ-6 development team designed a multi-satellite layout bearing cylinder and a multi-satellite separation control plan, to ensure that satellite-rocket interfaces are matched and coordinated. Meanwhile, given the strict requirement of multi-satellite launch for separation safety and the huge difficulty in separation design, in order to send 16 satellites into the preset orbit safely and accurately, the model carried out multi-satellite separation safety simulation and analysis for several times, and optimized the design in satellite layout and separation plans, etc. Finally, the batched separation plan was adopted, and lots of measures were taken, including adjusting rocket attitude before separation, and strengthening attitude control thrust, to ensure the safety of multi-satellite separation and the orbit injection accuracy. In spite of many challenges such as the compact layout, mutual spatial crossing, narrow docking and installation space, and huge operating difficulty of the 16 satellites inside the fairing, the model was properly arranged with satellite-rocket docking procedures, and also adopted measures of man-machine simulation, docking exercises, etc., to avoid risks.
This is another launch mission executed by CZ-6 launch vehicle in summer. Based on its “three-horizontal” launch test model, and no-support launch features, the model team further rechecked each rocket system for their rainproof and anti-thunder measures, including whether they are effective and how they are implemented on the rocket, to meet the pre-launch operation and launch requirements in thunderstorm season.
Underpinned by digital quality assurance, and focusing on key points at the launch site, CZ-6 development team has established 5 production assurance groups, including software assurance group, ground equipment assurance group, redundancy prevention and control group, connector and pipeline docking assurance group, and LDM management group. And the team has also practically completed all work at the launch site based on “advanced planning + process control”, “refined operation + refined management”, checked and confirmed all work quality records by the digital management system of the launch site, improved the efficiency of quality confirmation at the launch site, and ensured that all work is done for today.
This is the second launch mission of CZ-6-02 launch vehicle. Based on the breakthroughs made by its first launch in technical innovation, the model was further improved in the implementation of improved items, items that are easy to make mistakes and difficult to operate, mandatory inspection points, pre-launch process test coverage, launch plans, etc. All improved items have been implemented into the test rules, operating instructions, and other documents.
This is the 432nd launch of Long March series of launch vehicles, the 163rd flight test of the Long March series of launch vehicles developed by Shanghai Academy of Spaceflight Technology, and also the 9th launch of CZ-6 launch vehicle.
