And from a private source I just got info that suggests that yes, they have more than enough dV to get to the right orbit. Let's watch the TLEs over the coming days.

Тайюань, 28 декабря /Синьхуа/ -- В среду Китай запустил спутники дистанционного зондирования Земли с высоким разрешением.
В 11:23 по пекинскому времени с космодрома Тайюань в провинции Шаньси /Северный Китай/ с помощью ракеты-носителя "Чанчжэн-2D" был произведен успешный запуск двух спутников дистанционного зондирования Земли с высоким разрешением SuperView-1 01/02.
Спутники коммерческого назначения способны предоставлять изображения с разрешением 0,5 м.

The first perigee of the Gaojing sats was at 0428 UTC over #Guatemala. Still unclear how this relates to reentering debris seen around then

Based on the rules set out in http://planet4589.org/space/jsr/back/news.669 ... I am tentatively scoring the CZ-2D as 0.75 (off-nominal but usable orbit)

However it's plausible (likely?) the GJ sats have enough propellant to raise their orbits themselves, at some cost to their operational life

It's now clear that the ChangZheng-2D launch of the GaoJing satellites was a partial failure, leaving payloads in a lower than planned orbit

Chinese Earth observation satellites launched into lower-than-planned orbit             
 December 28, 2016 Stephen Clark


Two commercial Earth-imaging satellites launched by a Chinese Long March 2D booster Wednesday are flying in lower-than-planned orbits after an apparent rocket mishap, according to tracking data published by the U.S. military.
The two SuperView 1, or Gaojing 1, satellites are flying in egg-shaped orbits ranging from 133 miles (214 kilometers) to 325 miles (524 kilometers) in altitude at an inclination of 97.6 degrees.
The satellites would likely re-enter Earth's atmosphere within months in such a low orbit, and it was unclear late Wednesday whether the craft had enough propellant to raise their altitudes.
The high-resolution Earth-observing platforms were supposed to go into a near-circular orbit around 300 miles (500 kilometers) above the planet to begin their eight-year missions collecting imagery for Siwei Star Co. Ltd., a subsidiary of China Aerospace Science and Technology Corp., a government-owned entity.
The 1,234-pound-pound (560-kilogram) satellites lifted off at 0323 GMT Wednesday (10:23 p.m. EST Tuesday) from the Taiyuan space center in northern China's Shanxi province on top of a 13-story Long March 2D rocket, according to China's state-run Xinhua news agency.
The launch occurred at 11:23 a.m. Beijing time, marking China's 22nd attempted space launch of the year, and the 21st rocket mission to reach orbit.
But the two-stage launcher did not put the SuperView 1 satellites into the expected orbit, raising concerns among outside observers that the Long March 2D ran into problems.
The mission also carried a small amateur radio satellites made by Beijing high school students.
The SuperView 1 satellites are designed to collect optical black-and-white imagery with a resolution of less than 20 inches (about 50 centimeters), making them the highest-resolution civilian Earth-observing satellites launched by China.
The satellites can capture imagery in nearly 7.5-mile-wide (12-kilometer) swaths, turning to observe multiple locations on a single pass, or record images of the same point from multiple angles, allowing processors on the ground to generate stereo three-dimensional images.

Color images from the SuperView 1 satellites will have a resolution of around 6 feet, or 2 meters, according to information released by Beijing Space View Technology Ltd., which holds exclusive rights to distribute and sell SuperView 1 imagery globally for mapping, land use, urban planning, agricultural, oil and gas exploration, maritime, security, defense and intelligence applications, the company said.
Beijing Space View's sister-company Siwei WorldView is a joint venture between Siwei Surveying and Mapping Technology Co. Ltd., Navinfo and DigitalGlobe, the Colorado-based owner of the WorldView and GeoEye commercial Earth observation satellites.
The two distributors sell high-resolution imagery commercially in the Chinese market from China's own civilian-operated remote sensing observatories and international satellites like the WorldView and GeoEye series, South Korea's Kompsat family of spacecraft, Japan's ALOS satellite, the Spanish-owned Deimos missions, and Kazakhstan's KazEOSat 1 Earth observation platform.
The SuperView 1 satellites — if they can be salvaged and commissioned — would have given China its own commercial imaging spacecraft.
Two more SuperView satellites are scheduled to launch in mid-2017, and Siwei Star aims to have a fleet of more than two dozen Earth observation craft in orbit by 2022, including 16 SuperView-type optical satellites, four platforms with even better optical imaging capabilities, four X-band synthetic aperture radar satellites to observe through clouds and darkness, and multiple video and hyperspectral imaging spacecraft.

Так скруглят. Вопрос, до какой полуоси станут тянуть, чтобы на эксплуатацию еще топлива осталось.

Chinese satellites raising orbits after launch anomaly
by Jeff Foust — December 30, 2016

WASHINGTON — Two Chinese remote sensing satellites placed into a low orbit after an apparent problem with their launch vehicle are gradually raising their orbits and may still be able to carry out their missions.
The two SuperView-1 satellites launched at 10:23 p.m. Eastern Dec. 27 from the Taiyuan Satellite Launch Center on a Long March 2D rocket. Chinese media declared the launch a success, but satellite observers noted the two spacecraft were placed in elliptical orbits ranging from 214 to 524 kilometers rather than the planned circular sun-synchronous orbit at an altitude of 530 kilometers.
Since the launch, the two satellites have been gradually raising their orbits. Orbital data provided by the U.S. Air Force's Joint Space Operations Center indicated that as of early Dec. 30 one spacecraft, designated SuperView-1 01, is in an orbit of 352 by 526 kilometers. The other, SuperView-1 02, is in an orbit of 369 by 526 kilometers.
Such maneuvers would be consistent with the satellites using onboard propulsion to raise their orbits, at some cost to their lifetimes. A secondary payload on the launch, a student-built small satellite named BY70-1, is in an orbit of 214 by 518 kilometers, suggesting it lacks a propulsion system to raise its orbit.
Neither the owner of the SuperView satellites, Siwei Star Co. Ltd. of Beijing, nor other Chinese officials have commented on the apparent launch anomaly. Outside observers noted that the timing of several events during the launch, including the separation of the second stage from the first stage and the second stage's engine shutdown, were delayed from scheduled times by several seconds.
The two SuperView satellites are the first commercial Chinese high-resolution Earth imaging satellites. The spacecraft, each weighing 560 kilograms, carry cameras capable of taking images at a resolution of 0.5 meters per pixel. They will be joined by two similar spacecraft scheduled for launch in 2017, placed in the same orbit and separated from one another by 90 degrees.
Ultimately, Siwei Star Co. Ltd. plans to place 16 such spacecraft in orbit, in a constellation that will also include four satellites capable of even higher resolution imagery, four designed to produce synthetic aperture radar imagery and an unspecified number of hyperspectral and video satellites. That constellation, the company said prior to this launch, would be completed by 2022.

[Безумный Шляпник]

А какова была компоновка "головы" в этом запуске? На ступени сидит один "Гаоцзин", накрытый переходником, на переходнике сверху второй "Гаоцзин", и сверху ГО? Если так - тогда где этот "средний" переходник? У спейстрека его нет.

[Liss]

Кстати, да. Про компоновку вопрос интересный. Переходника не вижу.
Быть может, друг на друге стояли? А трубу куда?

 

A: 484.5x528.1
B: 510.2x531.2
Дотянули практически. И LTDN всего на минуту уполз.
 

[Безумный Шляпник]

Судя по



и



в наличии должен быть сложный ГО, состоящий из верхней и нижней частей. Нижняя часть при такой компоновке должна выходить на орбиту. А ее нет...
