#Gaofen-14 Satellite Successful Launch#

[Successful first flight! What are the new breakthroughs of the improved rocket Long March 3B - variant type 5?]

The modified CZ-3B rocket launched this time was developed by the China Academy of Launch Vehicle Technology. It uses a 4.2-meter-diameter extended fairing, with a total length of about 58 meters and a full rocket takeoff mass of about 456 tons. The rocket also adopted 12 first-flight technologies such as omni-directional take-off roll and active load reduction, which greatly improved mission adaptability and made further exploration in the direction of smart rocket development.

XICHANG, Jan. 20 (Xinhua) -- China successfully launched a new mobile telecommunication satellite from the Xichang Satellite Launch Center in southwest China's Sichuan Province on Wednesday.

The Tiantong 1-03 satellite was launched at 00:25 a.m. (Beijing Time) by a Long March-3B carrier rocket and entered the planned orbit successfully.

Tiantong-1 is a satellite mobile communication system independently developed and built by China. It consists of a space segment, ground segment, and user terminal.

Developed by the China Academy of Space Technology, the Tiantong 1-03 satellite will establish a mobile network with ground facilities to provide all-weather, all-time, stable and reliable mobile communication services such as voice, short message and data for users in China and its surrounding areas, the Middle East, Africa and other related regions, as well as most sea areas in the Pacific Ocean and Indian Ocean.

Wednesday's launch was the 358th by the Long March rocket series and also the country's first space launch in 2021.

In the past few days, several local confirmed cases of COVID-19 have appeared in Shijiazhuang, Hebei. In order to house the isolation of close contacts and sub-close contacts, houses have been erected! After 4 days of fighting day and night, the first batch of 1,008 container houses at the centralized isolation point was successfully delivered!

Seem making of that big dish is not easy.

据天通一号卫星副总师孙治国介绍,目前天通一号01星月均呼叫次数超过40万次,呼通率大于96%;02星完成20天快速测试后已投入使用。
据天通一号卫星总指挥边炳秀介绍,天通一号02、03星研制初期,天线分系统核心产品作为天通一号有效载荷通用关键产品,是唯一未能实现国产化的部件,面临着国外禁运、国内基础薄弱、无货可用的困境。为解决这一技术瓶颈,团队历时5年攻关,攻克了多个关键技术点,解决了从原材料选择到设计、加工、测试等一系列技术难题;最终,他们解决了“卡脖子”的技术难题,该产品成功实现国产化,在轨首飞任务获得圆满成功,在轨测试性能优异。​

According to Sun Zhiguo, deputy chief engineer of the Tiantong-1 satellite, the current monthly average number of calls on the Tiantong-1 01 satellite is more than 400,000, with a call-through rate greater than 96%; the 02 satellite has been put into use after completing a 20-day rapid test.

According to Bian Bingxiu, commander-in-chief of the Tiantong-1 satellite, in the initial development of Tiantong-1's 02 and 03 satellites, the core product of the antenna subsystem, as the key product of Tiantong-1's payload, was the only component that failed to achieve localization. Facing the difficulty of foreign embargo, weak domestic foundation and no product available. In order to solve this technical bottleneck, the team spent 5 years tackling key problems, conquering multiple key technical points, and solving a series of technical problems from raw material selection to design, processing, and testing; in the end, they solved the bottleneck technical problem, The product successfully realized localization, the first flight mission on orbit was a complete success, and the on-orbit test performance was excellent.
