SpaceX’s satellite is so powerful that it has the potential to reach hundreds of millions of customers. It’s the largest and most complex satellite ever built.

The Inmarsat-5 F4 will deliver mobile broadband for a third of the world’s population at 50 MB per second. By the end of 2018 those data rates will go up to over 300 MB per second.

The satellite will form part of the company’s Global Xpress network which has been supplying seamless, high speed broadband service around the world since December 2015.

The new satellite will join 3 others already in orbit.

Inmarsat has invested approximately US$1.6 billion in the Global Xpress constellation to establish the first ever global Ka-band service from a single network operator.

 

Inmarsat 5 F4 counts as the sixth SpaceX launch of 2017.

And SpaceX is on an absolutely torrid launch pace. Monday’s liftoff comes just 2 weeks after the last successful SpaceX Falcon 9 liftoff on May 1 of the super secret NROL-76 payload for the National Reconnaissance Office, or NRO
