ESA engineers are proposing a technique to enable a digital satellite radio service for European drivers – without the need to launch a single new satellite into orbit. Commercial digital satellite radio is already a reality in the United States, using a costly set of dedicated satellites. The rival American services allow subscribing drivers to choose between numerous near-CD quality radio channels without tune-out or static.
Two parallel ESA studies have examined a lower-cost method of providing in-car Europe-wide satellite radio. More here.
