“安溪铁观音二号”卫星（共包含5颗卫星）发射升空，卫星顺利进入预定轨道，发射任务取得圆满成功。 “道达星座”（“吉林一号”高分03D04～07星）是由长光卫星技术股份有限公司自主研发的轻小型高分辨遥感卫星，也是长光卫星的卫星批产产品，该系列卫星可为用户提供分辨率全色0.75m、多光谱3m，幅宽大于17km的影像产品，具有低成本、低功耗、低重量、高分辨的特点。“道达星座”由长光卫星与北京道达天际科技有限公司联合打造，计划共发射6颗新一代低轨高分辨率遥感卫星，组网建设完成后，可为金融、民航、交通、自然资源、应急管理等领域提供高质量的遥感信息和产品服务。 “安溪铁观音二号”卫星（“吉林一号”高分04A星）是长光卫星技术股份有限公司自主研发的新型高分辨遥感卫星，也是“吉林一号”星座高分04卫星的首发星，具有星上任务自主规划、实时数传和星上AI功能，结合快速机动控制，可实现单轨多点目标成像和信息快速回传。该卫星可获取分辨率优于0.5m、幅宽15km的静态推扫影像，具备高分辨率、高集成度和智能化特点。“安溪铁观音二号”卫星由长光卫星与安溪县人民政府、泉州中科星桥空天技术有限公司联合打造，依托海量卫星遥感数据及创新应用，为安溪县茶产业数字化建设赋予新动能，同时为“数字福建”建设注入鲜活动力。 “道达星座”和“安溪铁观音二号”卫星入轨后，“吉林一号”在轨卫星数量增至46颗，可对全球任意地点实现每天15～17次重访，“吉林一号”星座的地物分辨能力、拍摄覆盖能力及快速响应能力进一步提升，可为政府及行业用户提供更加丰富的遥感影像及数据产品，推动遥感服务向大众市场迈进。 此次任务是“吉林一号”卫星工程的第18次发射。

At 11:30 on April 30, 2022, Beijing time, my country successfully launched the "Daoda Constellation" and "Anxi Tieguanyin-2" satellites (including 5 satellites) with the Long March 11 Haisheyao-3 carrier rocket in the East China Sea. ) was launched into space, the satellite successfully entered the predetermined orbit, and the launch mission was a complete success.

"Daoda Constellation" ("Jilin No. 1" high score 03D04-07 stars) is a light and small high-resolution remote sensing satellite independently developed by Changguang Satellite Technology Co., Ltd. It is also a satellite batch product of Changguang Satellite. This series of satellites It can provide users with image products with a resolution of 0.75m in full color, 3m in multispectral, and a width greater than 17km. It has the characteristics of low cost, low power consumption, low weight and high resolution. "Daoda Constellation" is jointly built by Changguang Satellite and Beijing Daoda Skyline Technology Co., Ltd. It plans to launch a total of 6 new-generation low-orbit high-resolution remote sensing satellites. Provide high-quality remote sensing information and product services in the fields of resources and emergency management.

"Anxi Tieguanyin-2" satellite ("Jilin-1" Gaofen-04A satellite) is a new type of high-resolution remote sensing satellite independently developed by Changguang Satellite Technology Co., Ltd. It is also the first satellite of the "Jilin-1" constellation Gaofen-04 satellite. , with on-board mission autonomous planning, real-time data transmission and on-board AI functions, combined with fast maneuvering control, it can achieve single-track multi-point target imaging and fast information return. The satellite can obtain static push-broom images with a resolution better than 0.5m and a width of 15km, featuring high resolution, high integration and intelligence. The "Anxi Tieguanyin No. 2" satellite was jointly built by Changguang Satellite, Anxi County People's Government, and Quanzhou Zhongke Xingqiao Aerospace Technology Co., Ltd., relying on massive satellite remote sensing data and innovative applications, giving new momentum to the digital construction of Anxi County's tea industry , while injecting fresh energy into the construction of "Digital Fujian".

After the "Daoda Constellation" and "Anxi Tieguanyin-2" satellites are put into orbit, the number of "Jilin-1" satellites in orbit has increased to 46, which can revisit 15 to 17 times a day to any location in the world. "The constellation's feature resolution capabilities, shooting coverage capabilities and rapid response capabilities have been further improved, which can provide government and industry users with more abundant remote sensing images and data products, and promote remote sensing services to the mass market.

This mission is the 18th launch of the "Jilin-1" satellite project.
