At 19:06 on October 15, 2024, 18 satellites of the Qianfan Constellation Polar Orbit 02 Group were successfully launched aboard the Long March 6A carrier rocket at the Taiyuan Satellite Launch Center, and then successfully entered the scheduled orbit. Dianke Blue Sky developed energy system products such as stacked flexible solar wings, commercial digital power controllers and long-life battery packs for this mission.<\/p>\n
Different from the traditional aerospace “build one by one, launch one by one” model, Qianfan Constellation’s “batch networking and rapid deployment” puts forward higher requirements for energy system products. In order to meet the needs of the Qianfan constellation, Dianke Blue Sky has carried out a large number of technological innovations and successfully conquered many key technologies such as long-life and high-reliability interconnection and flexible array reliable compression buffering, achieving flat, lightweight, high-storage and low-cost solar wings; it has also successfully conquered the key technologies of integration and chip-based satellite energy systems. In order to achieve low cost and mass production, Dianke Blue Sky uses commercial off-the-shelf devices (COTS) on a large scale. The flexible solar wing and COTS-level digital power controller developed by it were applied in batches for the first time in the Qianfan Constellation Polar Orbit 02 satellite launch mission. Through continuous technological innovation, Dianke Blue Sky has introduced highly competitive technologies and products to the market, reshaping the aerospace energy industry.<\/p>\n
