US Federal Communications Commission (FCC) gives SpaceX permission to reduce the number of satellites in its home broadband connection the constellation from 4,425 to 4,409, just as it allowed to work at lower orbital altitudes than previously allowed.
While originally planned to operate at an altitude of 1,150 km, 1,584 Elon Musk's SpaceX satellites will now operate at 550 km, with related changes in their operations also granted.
In addition, SpaceX was authorized to use Ku-band gateway ground stations for less than 75 low-altitude (NGSO) non-geostationary satellites.
"After reviewing the record, we conclude that granting a SpaceX change request will serve the public interest," the FCC said. [PDF].
"Giving this change will enable SpaceX to use its valuable resources more efficiently, faster and more cost-effectively by initiating a new generation of broadband services that are available to customers around the world, including those areas that were previously under-served or even totally unsecured." . "
After SpaceX filed a request in November 2018, competing providers OneWeb and Kepler petitioned him against him, citing a greater opportunity for intervention. However, the FCC pointed out that there will be a decline in the number of SpaceX satellites.
"Therefore, we conclude that the number of spatial configurations that have the potential to generate interference between SpaceX and any other NGSS FSS system in the same processing wheel is expected to remain approximately unchanged," the commission said.
“We consider this to be an essential element in assessing whether serious interference problems would occur.
Gates that now use the 14-14.5 GHz band will also use larger narrower antennas, which the FCC has pointed out will be "more capable of preventing satellite interference".
He also describes with SpaceX how to avoid potential collisions – through the propulsion system to maneuver satellites to avoid collisions – in addition, the FCC has found that this risk is zero or zero.
The launch of global home broadband satellites was originally announced in November 2016, with SpaceX saying each unit will weigh 386 kg and measure 4×1.8 x 1.2 m.
"The system is designed to provide a broad range of broadband and communications services for residential, commercial, institutional, government and professional users around the world," SpaceX said at that time.

However, the company experienced difficulties; back in February, the Pentagon said it plans to investigate the certification that was granted to SpaceX's Falcon missile family to see if the US Air Force has followed the guidelines.
In 2015, SpaceX received the certification needed to launch military satellites.
"Our goal is to find out if the American Air Force has complied with the New Entrant Launch Services Certification Guide for the launch system design for the SpaceX Falcon 9 and Falcon Heavy launch vehicles for the Evolve Expandable Launch Vehicle," said Deputy Inspector General for News and Intelligence. A special program review by Michael Roark said.
In addition, in January, SpaceX announced what it calls "a necessary constraint" while removing 10% of its workforce to face "extremely difficult challenges in the future".
As reported by CNET's nurse, SpaceX and NASA are currently also investigating the cause of the Crew Dragon capsule engine failure.
