北京时间2022年4月29日12时11分，我国在酒泉卫星发射中心使用长征二号丙运载火箭，成功将四维01/02两颗卫星发射升空。卫星顺利进入预定轨道，发射任务获得圆满成功。该卫星主要为国内自然资源、测绘、海洋、环保等行业，以及城市安全、数字农村等新兴市场提供商业遥感数据服务。

此次任务是长征系列运载火箭第417次飞行。

China launched a CZ-2C rocket and successfully orbited two Siwei 01/02 commercial landscape remote sensing satellites at 12:11 UTC+8, April 29, 2022 from Jiuquan Satellites Launch Center.

This is the 417th CZ series rockets launch mission.





It's very strange that after I uploaded the first pic, I failed to upload the second, third and fourth ones for many times and the server told me they are too big pictures. They were not, and I had to compress the pics to very low quality.

Some high-resolution images of the latest Long March 2C launch, which lofted a pair of Siwei (四维) agile optical observation satellites into orbit. This was the 417th launch of the Long March series. The Siwei satellites each weighs 540kg, with a resolution of 0.5m, and are commercially operated by Siwei Survey and Mapping Technology Ltd.

Just adding some information. Siwei-1 is the upgrade version of Gaojing-1 (Superview-1). The CASC company operating both of them is named Siwei. To me it is like a re-branding of the same product line.

This clarification is important when we count the total number of satellites of the constellation in orbit. The final constellation consists 16 such 0.5m optical satellites, 4 0.3m optical and 4 0.5 SAR. So far we have Superview-1 (1, 2, 3, 4) in orbit. With Siwei-1(1, 2) we have in total 6.

Here is some details

4月30日11时30分，长征十一号运载火箭在我国黄海南部海域，以“一箭五星”方式托举吉林一号高分系列卫星点火升空，随后卫星被顺利送入预定轨道，发射取得圆满成功。
这是我国首次实现运载火箭海上“一站式”发射，即总装、总测、出港、发射一体化。
吉林一号高分03D04星~07星及高分04A星共包含5颗卫星，是由长光卫星技术股份有限公司出资自研的光学遥感技术卫星，主要用于获取高分辨可见光推扫影像和视频影像。5颗卫星与在轨的吉林一号卫星组网后，将为林业、农业、草原、海洋、资源、环境、城市建设等行业用户提供更加丰富的遥感数据和产品服务。

China launched a CZ-11 rocket and successfully orbited five Jilin-1 Hi-Res optical band remote sensing satellites in 11:30 UTC+8, April 30, 2022 from a ship-borne platform in the Yellow Sea.

The five satellites are Jilin-1 Hi-Res Group 03 D04~D07 and Group 04 A. They were designed for obtaining high resolution lightband image and video data, aimed for forests, arable land, grasslands, oceans, geographic resource, environment and metro landscape survey / monitoring.

This is the 418th CZ series rocket launch.

Well here is the video of Jilin satellite launch Any one keep track how many have been launched guesstimate 50?
