2 月24 日，航天宏图到雄安新区考察调研，表示要积极推动博士后工作站、有关研发中心设立和女娲雷达遥感星座落地新区。女娲星座计划旨在实现对地观测全球快速重访，利用激光星间通信组网，构建全球自主可控实时遥感混合星座。女娲星座一期工程计划发射38 颗业务星，其中有4 颗卫星预计于2023 年一季度发射，剩余24 颗卫星将于2024 年、2025 年发射。航天宏图是我国卫星应用与运营服务领域的领导者，业务模式从卫星应用产业链中下游向上游延伸演化，全面启动女娲星座计划建设工作，将打造出第二增长曲线

On February 24, Aerospace Hongtu went to Xiong'an New Area for investigation and investigation, saying that it would actively promote the establishment of post-doctoral workstations, related R&D centers, and the launch of the Nuwa Radar Remote Sensing Constellation in the new area. The Nuwa Constellation Project aims to achieve rapid global revisiting of Earth observation, and use laser intersatellite communication networking to build a global autonomous and controllable real-time remote sensing hybrid constellation. The first phase of the Nuwa Constellation project plans to launch 38 operational satellites, of which 4 satellites are expected to be launched in the first quarter of 2023, and the remaining 24 satellites will be launched in 2024 and 2025. Aerospace Hongtu is a leader in the field of satellite application and operation services in my country. Its business model has evolved from the middle and lower reaches of the satellite application industry chain to the upper reaches. It has fully launched the construction of the Nuwa Constellation Project and will create a second growth curve.

Впрочем, коллеги с NSF пытаются "запихнуть" на этот пуск все, что только в голову придет.
Зона годится под CZ-2D, CZ-4B/C и CZ-6, на выбор.

Связи с центральным бортом нет? Откуда данные отправляются на землю?

China Focus: China launches wheel-like constellation of remote-sensing satellites
^{Source: XinhuaEditor: huaxia2023-03-30 23:24:15}
BEIJING, March 30 (Xinhua) -- China launched a Long March-2D carrier rocket into space on Thursday evening carrying a wheel-like formation of four remote sensing satellites, the first formation of its kind in the world.
The satellites of the PIESAT-1 constellation were launched at 6:50 p.m. (Beijing Time) from the Taiyuan Satellite Launch Center in northern China's Shanxi Province, and then entered a preset orbit.

WHEEL FORMATION
The in-orbit constellation has formed a lineup like a vehicle wheel. It comprises a primary satellite running at the central "axle" and three supplementary satellites evenly placed in an elliptical "wheel hub" and orbiting the primary satellite. The supplementary trio is located just a few hundred meters from the primary satellite.
The constellation is capable of maintaining its stability and space safety, thanks to precise orbital control supported by inter-satellite links and phase synchronization links.
The four satellites are equipped with interferometric synthetic aperture radars (InSARs), which are effective tools to measure changes in land surface.
The InSARs capture two images at different times by reflecting radar signals off a target area on Earth, and then have them interfere with each other to produce maps called interferograms, which reveal the ground-surface displacement between the two time periods.
Unlike visible or infrared light, radar waves can penetrate most weather clouds and are equally effective in darkness.

DISASTER PREVENTION
Compared to traditional InSARs, a wheel formation can generate more interference baselines, thus increasing mapping efficiency.
The constellation, mainly used to provide commercial remote-sensing data services, is capable of conducting rapid high-efficiency global land surveys.
It can realize millimeter-level deformation monitoring to identify land subsidence, surface collapses and landslides, meaning it is an effective weapon for the early detection of major geological disasters.
The constellation has the full-time, all-weather ability to take high-quality, submeter-scale, broad-width images of our planet.
It was designed by the satellite maker Galaxy Space (Beijing) Network Technology, and it will be used by PIESAT, a satellite operation and application services provider in China.
The Long March-2D carrier rocket is a two-stage launch vehicle with a take-off thrust of 300 tonnes, and it is capable of lifting 1.3-tonne payloads to the solar synchronous circular orbit 700 km above Earth.
This mission was the 469th flight of the Long March carrier rockets.

China's SAST launched a CZ-2D at 1050 UTC Mar 30 placing four radar satellites in a 497 x 512 km x 97.4 deg, 18:00 LTDN sun-sync orbit. The CZ-2D second stage appears to have made a controlled deorbit soon after deploying the satellites.
...
Replying to @CNSpaceflight
CZ-2D upper stages have been deorbited fairly often
(although not always) since circa 2008

Вторая ступень, вероятно, была сведена.

Не маневрируют, хоть ты тресни :-(

Ага, испугались :-)
Зашевелились хунтятки. C и D начали поднимать орбиту. 
Интересно, как они собираются теперь сходиться в группу, если успели растянуться на 35° вдоль орбиты.

[Liss]

Маневрируют уже все четверо. B и C медленно сближаются, A и D продолжают расходиться, группа растянулась вдоль орбиты на 50°.

[Liss]

Группа поднялась до 516 км. По-прежнему B и C рядом в серединке, а от A до D почти 60° вдоль орбиты.

Так, что-то я не понял: какое имеет отношение товарищ Гао Эньюй и его MinoSpace к данному проекту?
