Traveling through time and space & Doing timey wimy stuff.

On 29th April 2022 1211 Hours Hong Kong SAR- Beijing time , the Belt and Road Initiative CNSA –China National Space Administration  launching from Jiuquan Satellite Launch Center – Inner Mongolia –China – People’s Republic of China, successfully   deployed two Earth Science  Remote Sensing  Siwei One / Two Satellite  with the Chang Zheng – Long March 2C carrier rocket on the satellite successfully entered the predetermined orbit….

The launch mission was a complete success. The satellite successfully entered the predetermined orbit, and the launch mission was a complete success. The satellite mainly provides commercial remote sensing data services for domestic natural resources, surveying and mapping, marine, environmental protection and other industries, as well as emerging markets such as urban security and digital countryside. This mission is the 417th flight of the Long March series of launch vehicles

The Chang Zheng – Long March 2C Carrier Rocket was developed by the First Academy of China Aviation, and the double star was developed by the Fifth Academy of China Airlines, which are used for global high-precision optical imaging. This launch is the 417th launch of China’s Long March series of launch vehicles


According to Li Jun, the chief designer of the Chang Zheng – Long March 2C Carrier Rocket this mission is a single-ten watch, a 3.35-meter fairing and a dual-star series launch state. It is also the second commercial launch of the Chang Zheng – Long March 2C Carrier Rocket in 2022. Co., Ltd., as the general contractor, provided the launch and on-orbit delivery to China Siwei Surveying and Mapping Technology Co., Ltd. ………This set the record for the shortest separation interval between stars and rockets of the Chang Zheng – Long March 2C Carrier Rocket – 3 separations of 3 objects in 2 satellites and 1 barrel section were completed within 3 seconds…

The Siwei 01/02 satellite 0.5-meter high-resolution high-performance optical commercial remote sensing satellite] According to the Fifth Academy of Aerospace Science and Technology Group, Siwei 01/02 satellite is two 0.5-meter high-resolution high-performance optical commercial remote sensing satellites, and the satellite user is China Siwei Surveying and Mapping Technology Co., Ltd. The 4D 01/02 satellite further improves the agile imaging capability of the satellite by optimizing the configuration of the satellite attitude control and measurement components: the front, lower and rear three-view stereo imaging can realize the 3D reconstruction of the ground target; the five-strip stitching imaging can realize a large area one-time rapid imaging Coverage; the multi-target imaging method of 20 targets in the same orbit makes rapid monitoring possible; the further optimized linear ground object tracking, active push-broom imaging, and north-south push-broom imaging along the earth have greatly improved imaging efficiency and satellite data. Acquisition capability; the high-efficiency data transmission system with large-capacity storage capability and the phased array antenna are used together to realize high-speed data download in fast maneuvering.


The Siwei 01/02 satellite is equipped with two high-precision space target imaging cameras, and the photosensitive pixels are replaced from traditional TDI CCDs to the most advanced CMOS devices. Image quality reaches new heights….

The Chang Zheng – Long March 2C Carrier Rocket completed an unimaginable challenge] The Chang Er C rocket used to launch the Siwei 01/02 satellite mission was officially clarified in early January this year. It was originally planned to be the launch window in mid-June was adjusted to the end of April.


In the face of the new design of the satellite and Chang Zheng – Long March 2C Carrier Rocket support structure and the new demonstration of the satellite separation plan, the pilot team of the second and third pilots of our pilot team completed the whole process in 3 months, “what is the use”, and completed the unimagined challenge…
