Musk: SpaceX's Starlink internet service will work in high-speed trains

SpaceX’s satellite internet network, Starlink, may deliver broadband to people’s homes and their cars, according to CEO Elon Musk. 

On Tuesday, Twitter user Anton Kanerva asked Musk whether Starlink’s satellite dishes will work over “high-speed moving objects like trains.” He added: “It would be incredible if trains moving through the middle of nowhere finally could have stable high-speed internet connections!”

In response, Musk tweeted back: “Yes. Everything is slow to a phased array antenna.” 

The comment references how Starlink operates over hundreds of satellites orbiting above the Earth at around 350 miles. At this range, even a fast moving train would appear relatively slow to a Starlink satellite as it beams the internet data toward Earth. Read more...
