Long March 2 Ding carrier rocket.
Ignition at the Jiuquan Satellite Launch Center.
Successfully will be high score 9 05 stars and two carrying stars.
Into a predetermined orbit.
The launch was a complete success.
This is the seventh launch of the Long March II Ding carrier rocket this year.
The Long March 2 Ding carrier rocket (hereinafter referred to as the Chang Erding rocket) used in this launch is a normal-temperature liquid secondary launch vehicle developed by China Aerospace Science and Technology Group Co., Ltd., with a take-off thrust of about 300 tons, corresponding to 700 km of solar synchronous circular orbit carrying capacity of 1.2 tons, with different orbit requirements of single-star, multi-star launch capability. High score 9 05 star by the five houses of space Oriental Red Satellite Co. , Ltd. to grasp the total development.
On the basis of high reliability, changed two Ding rocket has a strong environmental adaptability and thoughtful service guarantee, can be in the country's three major satellite launch centers to carry out tasks, regardless of wind, summer, autumn and winter, to provide satellites with a comfortable ground environment, flight environment.
This launch, the rocket is facing the challenge of summer high temperature environment: some rocket products or ground test equipment, especially precision equipment for environmental protection temperature requirements are high, model team item by item combing product protection requirements and measures to ensure that each single-machine environmental protection conditions meet the requirements; Put forward reasonable storage temperature control requirements, coordinate the launch center to ensure propellant filling temperature, the whole process of controlling the parking temperature, to ensure that the launch on time; In 2021, the Chang'e Ding rocket will also fully implement the image measurement system, the rocket flight segment observation will be more intuitive.
Since May 2020, the Chang'e Ding rocket has carried out five rocket launches in a row. Long two Ding rocket created 60 days of five-fight five-jet, 40 days off-site 4 rounds, 30 days in the same place two consecutive launch records, such as a record, this one thanks to the model team's early planning, early advance. As early as 2017, the model from the hardware miniaturization, automation, intelligence, high reliability and other aspects of technological innovation and upgrading, at the same time, the management of continuous process optimization, staffing streamlined and effective, so that "compact progress, standards do not decrease", the annual launch of several rockets during the launch site did not occur quality problems, strict quality control effectively ensure the smooth progress of the process. At present, the eight hospitals have set up a full-time launch site survey team, for the eight hospitals rapid response, quality and quantity to complete intensive launch missions to provide more professional personnel protection.
The main star of the launch is the high-score 905 star, mainly used in land census, urban planning, crop assessment and disaster prevention and mitigation and other fields.
The launch was the 51st launch of the Chang'e Ding rocket, the 121st flight test of the Long March series of launch vehicles developed by the eight hospitals, and the 343rd launch of the Long March series of launch vehicles.

"Congratulations! On August 23, 2020, at 10:27 a.m., China successfully launched the High Score 9 05 into its intended orbit using the Long March 2 Ding carrier rocket at the Jiuquan Satellite Launch Center. The mission also carried the launch of a multi-functional test satellite, Tianto V satellite. High score 9 05 star is an optical remote sensing satellite, ground pixel resolution up to sub-meter level, mainly used in land census, urban planning, land rights, road network design, crop assessment and disaster prevention and mitigation and other fields, for the "Belt and Road" construction to provide information protection."

JIUQUAN, Aug. 23 (Xinhua) -- China successfully launched a new optical remote-sensing satellite from the Jiuquan Satellite Launch Center in northwest China at 10:27 a.m. Sunday (Beijing Time).
The satellite, Gaofen-9 05, was sent into orbit by a Long March-2D carrier rocket.
Gaofen-9 05 has a resolution up to the sub-meter level. It will be mainly used for land surveys, city planning, land right confirmation, road network design, crop yield estimation and disaster prevention and mitigation.
It will also provide information for the Belt and Road construction.
A multifunctional test satellite and another satellite named Tiantuo-5 were also launched via the rocket.
The multifunctional test satellite was developed by the Academy of Military Sciences and will test and verify technologies such as communication, navigation and remote sensing in orbit.
Tiantuo-5, developed by the National University of Defense Technology, will test and verify data collection technologies for ships, aircraft, buoys and the Internet of things.
Sunday's launch was the 343rd mission of the Long March rocket series.

So if we believe in patches, GF-9 04 is not a part of the constellation composed from 02, 03, and 05.

That actually makes sense when you ignore -01, they are spaced at +- 1h30 and +-3h for solar noon. I since -01 and -04 have close but not identical orbital planes, and -01 orbits much higher than the others, I think the actual constellation is -02-05, and -01 is a one-off.

(CONFIRMED) The launch of GF-9-05 today is the 7th & final LM-2D launch of 2020.

On October 16 GF-9 05 maneuvered into the 495.5 km orbit following GF-9 04 and 03 earlier. Only GF-9 02 has not maneuvered yet.
The 495.5 km orbit after maneuver is typical for the septet (YG-12/21, YG-14/28, YG-26/GF-8, GF-11), not for the LKW family.
