The entire
globe can be provided with affordable high-speed Internet from satellites in
space. These newly developed mini-satellites in a low-earth orbit as well as
powerful antennas and signal processing chips make this possible.
The digital
revolution has radically changed the way we live and work. But more than three
billion people are still offline. As with any infrastructure, fast data
connections initially reach urban centers. People who live in rural areas, even
in rich industrialized countries, often have to get by without reduced
bandwidth. Now several consortia are competing to bridge this gap with the help
of hundreds of mini-satellites in low orbit.
The idea is
not entirely new: 25 years ago, others already failed because of their
over-ambitious plans and technical limitations. It is only now that high
numbers of satellites can be produced quickly and cheaply through automation
and mass production. In February 2019, the OneWeb consortium launched the first
six 150-kilogram satellites into a low-earth orbit.
On their way
to their final orbit at an altitude of 1,200 kilometers., the satellites must
pass through a dense array of GPS and Earth observation satellites as well as
the space debris of the past 60 years. Collisions are not exceptional. And
hundreds more mini-satellites in space will mean even more space debris in the
future.
Dozens of
ground stations are needed around the globe to supply the numerous satellites
with Internet data and receive data from space. This requires sophisticated antenna
technology, which is also as yet available on the necessary scale. Not to
mention the difficult regulatory challenges facing Internet providers in over
200 states and territories.
The original
release date of this documentary was 2019.
