At 21:38 on September 26, 2022, CZ-2D Y-68 launch vehicle was successfully launched at Xichang Satellite Launch Center, sending Remote Sensing Satellite-36 into the target orbit. The launch task was a complete success. China Academy of Space Technology and Shanghai Academy of Spaceflight Technology took charge of the general development work of the satellite respectively.

CZ-2D refreshed the model’s launch record in a single month

CZ-2D launch vehicle for this task is a normal-temperature liquid two-stage launch vehicle developed by Shanghai Academy of Spaceflight Technology of China Aerospace Science and Technology Corporation. It has a takeoff thrust of about 300 tons, a carrying capacity of 1.3 ton in the sun-synchronous circular orbit with a height of 700 km, the single-satellite and multiple-satellite launching capabilities meeting the requirements of different orbits.

This is the third launch mission of CZ-2D in September. It sets a new record of the launch times of the “model rockets” in one month since they were put into service. So far, CZ-2D has finished 9 launch missions this year, and sent a total of 26 satellites into the target orbit. The model team carried out multiple missions at multiple launching sites simultaneously, which demonstrated the concrete actions of these experienced staff in contributing to China’s space undertakings following the work style with solid and steady steps under the current high density launch model.

This launch task is the 439^th launch task of Long March launch vehicles, the 169^th flight test of Long March launch vehicles developed by Shanghai Academy of Spaceflight Technology, and the 66^th launch task of CZ-2D launch vehicle.

Satellite C created a new record of the shortest dwelling time of a single satellite developed by Shanghai Academy of Spaceflight Technology at the launching site

In order to give full play to the vanguard and exemplary role of Party members, and to encourage team members to shoulder heavy responsibilities and step forward, the R&D team set up a responsible team consisting of multiple responsible Party members. With the determination and confidence of “never giving up until the task is completed”, the team worked strictly and speedily, sacrificed festivals and holidays, and successfully finished the large-scale tests before factory release.

Facing the “three-high” requirements, the model team adopted the three-dimensional digital design platform and full-cycle information-based management platform in all the stages including the general design, single unit development, product delivery, and final assembly and integration test, which not only strengthens the control of the product technical state, but also improves the design efficiency. The model team replaced the traditional meeting review with table-based confirmation.  In factory release, 27 A tables and 136 B tables were issued, which greatly guaranteed the successful factory release work.

The test team members arrived at the test base in the middle of May. Since then, they have been working on the front line of satellite launching, and have set a new record for Shanghai Academy of Spaceflight Technology, namely, the shortest dwelling time of a single satellite at the launching site, and the largest number of satellites launched within the shortest time.

In response to the ahead-of-schedule transition of C satellite, the team members tackled difficulties head on and worked persistently. They finished the load test items in advance on the premise of ensuring the health state of the platform, and carried out wireless testing simultaneously with peer units, during which platform test was also conducted. This has greatly reduced the electrical test time in the technical area. On this basis, the team members worked jointly to catch up with the schedule, and finished all the work in the technical area within only 7 days.

In the satellite test team, one person is responsible for multiple tasks. During the Mid-Autumn Festival, they worked in the electrical testing room and factory hall alternately, and conducted the electrical testing with uninterrupted power supply for more than 60 hours. With their concrete actions and hard work, they have achieved a 100% planned completion ratio and a 100% product qualification ratio.
