<\/p>\nThe China Aerospace Science and Technology Corporation (CASC) has launched the 13th Chang Zheng 11 (CZ-11) to deliver five Jilin-1 Gaofen Earth observation satellites to a Sun-Synchronous Orbit (SSO). This launch is the third CZ-11 (CZ-11H) to be launched from an offshore launch platform off the coast of China. CZ-11H Y3 launched on April 30 at 03:30 UTC from the Tai Rui launch platform just offshore of China.<\/p>\n
This was the 13th launch from China in 2022 and the 418th overall launch of the Chang Zheng series of rockets.<\/p>\n<\/p>\n
CZ-11 is the first and only all-solid Chang Zheng rocket currently in operation. The rocket was developed by the China Academy of Launch Vehicle Technology (CALT) as a cheap, simple, and reliable launch vehicle to enable a quick-reaction launch. Due to its all solid-based stages, CZ-11 can be placed into storage and launched when needed.<\/p>\n
The rocket is classified as a small-satellite launch vehicle able to lift 700 kg to low-Earth orbit (LEO) and 350 kg to a 700 km SSO. The rocket uses four stages with a reaction control system on the fourth stage. At the time of its first launch, the first stage was the largest solid rocket motor developed as a first stage by China. At liftoff, CZ-11 can generate 1,176 kN of thrust.<\/p>\n
The rocket itself is 20.8 meters tall with a diameter of 2.0 meters. CZ-11 has two optional fairing sizes of 1.6 meters and 2.0 meters.<\/p>\n

If launching from an offshore launch platform, CZ-11 takes the designation of CZ-11H. This time, CZ-11H used the Tai Rui launch platform. The platform is roughly 110 meters by 80 meters in size. Tai Rui was positioned off the coast of Shanghai at 123.8E 32.2N.<\/p>\n
CZ-11H has also launched from the De Bo 3 launch platform. De Bo 3 was used for the second CZ-11H launch.<\/p>\n
Aerospace & Defense (adsbygoogle = window.adsbygoogle || []).push({});<\/p>\n Normally, the CZ-11 launches from land-based launch sites in China. Its primary launch site is Site 95 at the Jiuquan Satellite Launch Center. Site 95 has supported eight launches. Another CZ-11 launch site is the Xichang Satellite Launch Center with three launches.<\/p>\n On September 25, 2015, the maiden flight of a CZ-11 took place from Site 95 at Jiuquan. From the same launch site, on January 19, 2018, CZ-11 launched its first set of Jilin-1 satellites and rideshare payloads to SSO.<\/p>\n On June 6, 2019, the first CZ-11H launched from Tai Rui with a Jilin-1 satellite plus other rideshare payloads. The most recent launch of a CZ-11H was on September 15, 2020, from the De Bo-3 with a set of nine Jilin-1 satellites. CZ-11 currently has a perfect launch record of 13 launches and 13 successes.<\/p>\n Jilin-1 is a series of Earth observation satellites operated by Chang Guang Satellites Technology Corporation. The first four Jilin-1 satellites were launched on a CZ-2D in October 2015. Over 40 Jilin-1 satellites have been successfully launched to orbit. The plan is to launch 138 satellites by 2030.<\/p>\n Jilin-1 has launched across multiple different launch vehicles since its first launch. These satellites have launched on CZ-2D, Kuaizhou-1A, CZ-6, CZ-11, Kuaizhou-11, Hyperbola-1, and CZ-8. Jilin-1 has a planned upcoming launch from Site 95 at Jiuquan on the Hyperbola-1 rocket.<\/p>\n Artist impression of the Jilin-1 Gaofen-03D.

Satellites 04 to 07 were launched along with a single Jilin-1 Gaofen-04A. Jilin-1 Gaofen-03D is a 42 kg satellite set to get a narrow field-of-view image of the Earth\u2019s surface. These satellites use new cameras, structures, and electronic systems to keep costs and weight low. The Jilin-1 Gaofen-03D will have imagery of 0.75 meters.<\/p>\n Jilin-1 Gaofen-04A is a prototype satellite for the Jilin-1 Gaofen-04 series. This satellite will use static push-broom images with a resolution better than 0.5 meters. The images collected with has a width greater than 15 km to provide high-resolution imagery. It will also use onboard mission autonomous planning, real-time data transmission, and onboard AI functions. Using the new software and single-tracking multi-point imaging with rapid information return.<\/p>\n The satellites will be launched into roughly a 535 km SSO. For the five satellites onboard, the mission was named \u201cone arrow and five stars.\u201d<\/p>\n Once the 138 satellites are launched, the full constellation will enable round-the-clock, all-weather, and full-spectrum data acquisition to provide geospatial information and services of high temporal and spatial resolution.<\/p>\n This year, more CZ-11s are expected to launch. In 2022, five to eight launches are planned with up to three sea launches.<\/p>\n CZ-11 will soon see a major upgrade. Named the CZ-11A, it will see a new 2.4-meter first stage to increase its payload capability. This CZ-11A rocket will make its first launch in late 2022.<\/p>\n (Lead photo: CZ-11H launches from the Tai Rui sea launch platform.)<\/em><\/p>\n","protected":false},"excerpt":{"rendered":" The China Aerospace Science and Technology Corporation (CASC) has launched the 13th Chang Zheng 11 (CZ-11) to deliver five Jilin-1 Gaofen Earth observation satellites to a Sun-Synchronous Orbit (SSO).
