Amazon's Kuiper System satellites will have a design life seven years — less than half that of a traditional geostationary communications satellite — and will be launched in five waves, according to a July 4 filing with the U.S. Federal Communications Commission. 

The first wave consists of 578 satellites that would provide internet service in two horizontal coverage bands, one between 39 degrees north and 56 degrees north (roughly from Philadelphia north to Moscow) and another from 39 degrees south down to 56 degrees south (roughly from Hastings, New Zealand, to the top of Great Britain's South Sandwich Islands in the Atlantic Ocean). The subsequent four waves would fill in coverage to the equator.
