5 Satellites launched for AST direct-to-smartphone broadband constellation

SpaceNews reports that AST have launched the first 5 satellites for their SpaceMobile constellation, which will provide satellite broadband direct to mobile phones.

They will need to launch around 45-60 satellites to provide continuous service in the US.  These first 5 satellites will only be able to provide intermittent service - in total less than 1 hour per day in the US.  They initially expect this to be used for services such as remote monitoring devices or emergency backups. 

“It is too early to give a specific date on when this service will become available,” he added, “but the Sept. 12 satellite launch is a major milestone toward making this vision a reality.”
