According to the "China Aerospace Science and Technology Group" public account, at 11:58 on December 6, the Long March 3B carrier rocket was ignited and launched at the Xichang Satellite Launch Center, and then the Gaofen 14 satellite was sent into the scheduled orbit and launched A complete success.
This is the first launch of the Long March 3B modified V carrier rocket (hereinafter referred to as the "Chang 3 B to 5 rocket") and the first launch of a sun-synchronous orbit satellite by the Long March 3 A series carrier rocket.
The modified Long Three B rocket launched this time, under the overall design framework of the Long Three A series rockets, compared with the Long Three B/Expedition One rocket, it uses a 4.2-meter long fairing with the same diameter. The rocket is full length It is about 58 meters long, and its takeoff mass is about 456 tons. In order to adapt to this mission and take into account the follow-up development, the rocket also adopted 12 first-flight technologies such as omni-directional take-off roll and active load reduction, which greatly improved the adaptability of the mission and made further explorations in the direction of smart rocket development. The
Gaofen 14 satellite is an optical three-dimensional surveying and mapping satellite arranged by the National Science and Technology Major Project of the High-resolution Earth Observation System. It can efficiently obtain high-precision three-dimensional images worldwide, measure large-scale digital topographic maps, and produce digital elevation models and figures. Products such as surface model and digital orthophoto map provide basic geographic information guarantee for national economic development and the "Belt and Road" initiative. This launch of
is the 354th launch of the Long March series of carrier rockets.
