China successfully launched one group of "Jilin-1" commercial satellites

At 12:13 on October 7, China successfully launched a group of "Jilin-1" commercial satellites (1 optical remote sensing satellite, 2 video satellites and 1 technology verification satellite) with the Long March-2D carrier rocket at the Jiuquan Satellite Launch Center
.
China's space remote sensing application field commercialization and industrialization development has taken an important step
.

The Long March 2D carrier rocket ignited and took off

The Jilin No.
1 commercial satellite group includes one optical remote sensing satellite, two video satellites and one technical verification satellite, all of which operate in sun-synchronous orbits
about 650 kilometers high 。 Among them, Jilin No.
1 optical A satellite is China's first self-developed high-resolution earth observation optical imaging satellite, with conventional sweeping, large angle side swing, same orbital stereo, multi-strip splicing and other imaging modes, ground pixel resolution of panchromatic 0.
72 meters, multispectral 2.
88 meters, can be used for land resources monitoring, land surveying and mapping, mineral resources development, smart city construction, transportation facilities monitoring, agricultural production assessment, forestry resources census, ecological environment monitoring, disaster prevention and mitigation, Remote sensing data support
is provided in areas such as public emergency health.
The ground pixel resolution of Jilin No.
1 video star is 1.
12 meters, which mainly carries out high-resolution video imaging technology experimental verification, which can provide users with a new experience
of remote sensing video.
Jilin No.
1 technology verification star mainly carries out multi-mode imaging technology test verification
.

The four satellites are developed and commercialized by Changguang Satellite Technology Co.
, Ltd.
, and after the satellites are put into orbit and worked, the company will provide satellite remote sensing data and products
at all levels to domestic and foreign users through online and offline methods.
It is understood that Changguang Satellite Technology Co.
, Ltd.
is a satellite commercial operation carrier jointly established by the Jilin Provincial Government, Changchun Institute of Optics and Mechanics of the Chinese Academy of Sciences and private capital, and is an important force
to promote the industrialization of China's aerospace remote sensing commercialization.
In the future, the company will also develop and launch a series of high-resolution remote sensing satellites to provide users with high-resolution remote sensing information products
worldwide.

The launch vehicle used for this launch was developed by the Shanghai Academy of Aerospace Technology
, a subsidiary of the China Aerospace Science and Technology Corporation.
This is the 213th flight
of the Long March series of launch vehicles.
