BlackSky is planning to expand the capabilities of its Earth Observation (EO) constellation with multispectral, large-area collection satellites called AROS, to launch “as early as 2027.”

BlackSky explained the AROS satellites are designed to support country scale digital mapping, navigation, maritime, and 3D digital twin applications. The company said the AROS plan has been in development for the past two years and was a key factor in the company’s move to acquire the full stake in its manufacturer, LeoStella late last year. 

While the new Gen-3 satellites are designed for high-frequency site monitoring, AROS is designed for broad area search, change monitoring, and refresh of large area and 3D mapping datasets.

The AROS system is planned to operate as an integrated extension of BlackSky’s existing fleet. BlackSky did not specify the number of satellites for AROS. BlackSky explained the integrated constellation will combine “very high-resolution broad area search with site monitoring to provide dynamic tipping and cueing for advanced maritime and Golden Dome type applications.” 

BlackSky said it will fill “upcoming gaps in the market as legacy large area collection satellites age out of service over the next few years,” with “disruptive speed and more favorable economics.” 

“As legacy satellites approach end-of-life, we see a critical opportunity to address market needs — not just in performance and agility — but also in affordability and AI-readiness. As confirmed through active customer and partner engagement, BlackSky is meeting the modern demands of governments and commercial users who need persistent visibility over very large areas, fast,” said Brian O’Toole, BlackSky CEO.
