SpaceX Starlink One Million Ground Stations

ARS Technica has the detail:

SpaceX is seeking US approval to deploy up to 1 million Earth stations to receive transmissions from its planned satellite broadband constellation.

[. . .]

A new application from SpaceX Services, a sister company, asks the FCC for “a blanket license authorizing operation of up to 1,000,000 Earth stations that end-user customers will utilize to communicate with SpaceX’s NGSO [non-geostationary orbit] constellation.”

FCC tells SpaceX it can deploy up to 11,943 broadband satellites
If each end-user Earth station provides Internet service to one building, SpaceX could eventually need authorization for more than 1 million stations in the US. SpaceX job listings describe the user terminal as “a high-volume manufactured product customers will have in their homes.”

“These user terminals employ advanced phased-array beam-forming and digital processing technologies to make highly efficient use of Ku-band spectrum resources by supporting highly directive, steered antenna beams that track the system’s low-Earth orbit satellites,” SpaceX’s new application says. “Consistent with SpaceX’s space station authorization, these Earth stations will transmit in the 14.0-14.5 GHz band and receive in the 10.7-12.7 GHz band… SpaceX Services seeks authority to deploy and operate these Earth stations throughout the contiguous United States, Alaska, Hawaii, Puerto Rico, and the US Virgin Islands.”

“The proposed user terminal is a flat phased array capable of steering its beams to track SpaceX’s NGSO satellites passing within its field of view,” the application also says. “As the terminal steers the transmitting beam, it also adjusts the power to maintain a constant level at the receiving antenna of its target satellite, compensating for variations in antenna gain and path loss associated with the steering angle.”

[. . .]

In addition to user terminals, SpaceX plans a smaller number of gateway Earth stations to “provide the necessary communications links back from the SpaceX satellites to the global Internet,” according to a previous SpaceX filing. SpaceX has estimated that it will deploy “several hundred” of these gateway stations across the US to be “co-located with or sited near major Internet peering points to provide the required Internet connectivity to the satellite constellation.” SpaceX also plans two tracking telemetry and control (TT&C) stations in the US, one on the East Coast and another on the West Coast.

Launches are scheduled for mid-2019 with service starting in 2020. I am looking forward to having a terminal on my roof. Stay Tuned for more details.
