Improve the efficiency of information acquisition Continental ultra-low orbit satellites plan to launch in SeptemberMainland China's "Global Times" reported that, according to the Second Academy of Aerospace Science and Industry of China, the Academy is currently planning the construction of an ultra-low orbit satellite constellation, which will meet the conditions for the launch of the first satellite in September this year. If completed, it will effectively reduce the cost of satellite development and launch, and improve the efficiency of information acquisition and transmission; in the face of random emergencies, it will be able to respond quickly and obtain high-resolution image data in a short period of time.
Is ULEO a common term in the chinese aerospace industry, rather than VLEO?
The construction of the ultra-low orbit integrated satellite constellation has officially started, and the first satellite is planned to be launched in DecemberCreate an ultra-low orbit constellation and its application system integrating "sensing, transmission, and calculation". It is estimated that 192 satellites will be completed in 2027, and 300 satellites will be completed in 2030...On July 12, at the Ninth China (International) Commercial Aerospace Summit Forum held in Wuhan, Hubei, China Aerospace Science and Industry Corporation announced the official launch of the construction of an ultra-low orbit integrated satellite constellation. The first star has completed the prototype product design It will be equipped with optical remote sensing cameras, on-board intelligent processing equipment, atomic oxygen detectors and other payloads, and is planned to launch in December.According to the relevant person in charge of the Space Engineering General Department of China Aerospace Science and Industry Corporation, ultra-low orbit refers to an orbit with an orbital height lower than 300 kilometers. The effect of rapid decay due to atmospheric drag. Although the long-term operation of ultra-low orbit needs to face many technical challenges, it also contains ultra-high value. Due to the decrease of orbit height, the earth observation has changed from "remote sensing" to "near observation", which can achieve lower cost and higher observation resolution High rate, shorter transmission delay and other effects, the optical load weight and cost are reduced by about 50% under the same resolution.The ultra-low orbit integrated satellite constellation aims to create an ultra-low orbit satellite constellation and application system that integrates "sensing, transmission, and calculation". On-board intelligent processing, star-terminal direct connection, and inter-satellite communication realize spatial information direct access to user terminals.According to the construction plan issued by the General Department of Space Engineering of China Aerospace Science and Industry Corporation, the ultra-low orbit and remote integrated satellite constellation will be implemented in three stages in accordance with the principles of overall planning, step-by-step implementation, and gradual improvement. It is planned to complete the ultra-low orbit and remote communication in 2023. The first satellite launch of the integrated satellite constellation is planned to complete the launch of the 9-satellite service verification constellation cluster in 2024. It is expected to complete the 192-satellite in-orbit network in 2027, and the 300-satellite in-orbit network operation in 2030, forming a global 15-minute response capability. Boost the development of space economy.
Combined with market demand, the Kuaizhou-11 rocket will arrange multiple launch missions from 2023 to 2024, some of which still have load margins, and can provide "high reliability, low cost, and fast response" carry-on launch services. Fast boat 11 cabins, waiting for you!

Fast boat 11 cabins, waiting for you!The Kuaizhou-11 might be launched in 4Q.Can you please explain where is the relation between a possible KZ-11 launch and the launch of the ULEO/VLEO satellite? Or are you only guessing that the KZ-11 can be used for this mission?
Side notes on the year-end mission of the Aerospace Science and Technology Group Chang-II C rocket test teamEntering November, the Chang 2-C rocket test team began to "accelerate". According to the plan, the test team will complete three consecutive space missions at the Jiuquan Satellite Launch Center before the end of the year.November 16th is the 66th anniversary of the establishment of the First Institute of Aerospace Science and Technology Group. At noon that day, good news came from the front that the Long March 2C carrier rocket was successfully launched, and the "three consecutive launches" were successful.On December 4, the Long March-2C carrier rocket launched the Egypt-2 satellite and the Xingchi-1 A/B satellite into the predetermined orbit in a "three-star with one stone" manner, successfully completing the 499th launch of the Long March series of carrier rockets. emission.
Civilian satellite enters extremely low Earth orbitThe first commercial extremely low Earth orbit satellite may be launched before the end of December, depending on the progress of China Aerospace Science and Industry Corporation (CASIC) and EOI Space. Both companies claim they are pioneering a beyond-line-of-sight idea that would bring satellites closer to Earth than today's rapidly growing constellations of low-Earth orbit (LEO) satellites.

One more question, is it the same launch as 27 Dec?
I have taken a look at the drop zones and I now think this is a CZ-11 launch instead.The final drop zone in the south Pacific is around 8200 km downrange, which is further than almost any other Chinese solid rocket motor based launchers. In particular, the downrange drop zones (3rd stage?) for KZ-1A is around 7500 km away, and Ceres-1 is closer to 6500 km. This measurement comes from the most recent non-polar LEO launches for these 3 rockets (CZ-11: Shiyan 21 from Xichang, Dec 2022 - it has never flown anywhere but SSO from Jiuquan so far; KZ-1A: Longjiang 3, Jun 2023; Ceres-1: Tianqi 21-24 sea launch, Sep 2023).Also note that CASC/CALT did NOT declare their works of 2023 have ended after the CZ-3B/Beidou launch today, as per tradition - that to me strongly hints at CZ-11 flying again before the year is out.
