低轨卫星19组成功发射：银河航天承担研制，GW星座部署提速

Group 1 - The deployment speed of the GW constellation has accelerated from a "bi-monthly launch" to a "weekly launch" within 13 months, with the latest batch of 19 satellites launched just 6 days after the previous group [1] - The GW constellation features a dual-layer design, with the GW-A59 sub-constellation planning for 6,080 satellites in very low Earth orbit (VLEO) below 500 km, and the GW-A2 sub-constellation planning for 6,912 satellites in low Earth orbit (LEO) at 1,145 km [1] - The satellites are developed by Galaxy Space, which has independently undertaken the development of two groups of such space infrastructure satellites, utilizing advanced technologies such as phased array antennas and digital full-process integration for cost-effective production [1] Group 2 - The recent launch is the second mission from the Hainan commercial space launch site in 2026 and marks the 12th successful launch from this site [2] - A new command team was introduced for this mission, including five new commanders, with the chief commander being a post-90s individual, marking a first for the Hainan commercial launch company [2] - The team implemented a "status confirmation system" to optimize task processes and improve work efficiency, accommodating the high-frequency networking demands of the SF-13 mission [2]
