So it should be celebrated that on December
8, 1993, the system became fully functional
and with it, changed the way the world
works. It opened up new frontiers in global
commerce and has become a lifesaver in
many situations that would have been
considered hopeless previously.

"Now is the proper moment to fully
appreciate what GPS provides and
acknowledge that even one day without
GPS is a scary prospect. The most obvious
downside is also one of the least important –
without reliable GPS it would be far easier
for drivers, walkers – anyone really – to get
lost. But this marvel of American ingenuity
and tenacity is much more. It is the
foundation of American commerce, safety and defense."

He explained that the timing data GPS
provides is the system’s most important
capability as it enables 14 of 16 of the US's
critical infrastructure sectors and this can be
extrapolated to a number of nations around
the world – and that if GPS suddenly ceased
to function the effects could be catastrophic.
Without the system shipping around the
planet would struggle and have to slow to a
near halt as "the choreography of ships and
trucks transporting imported goods is based
on an intricate GPS-derived schedule and
GPS-enabled tracking and co-ordination
software". There would be increased costs
for most goods and services and the world's
airlines would suffer. Even accessing bank
accounts, among many other functions of
daily life that are taken for granted, would become harder.

Lt Col Robert Wray continued: "The Space

Working 24/7, a team of Guardians,
supported by Air Force airmen and civilians, ensure GPS never fails.
"Indeed, in the history of this constellation,
GPS has never failed in its mission to
provide 100 percent global coverage, 100
percent of the time. There are limitations, of
course. GPS is not designed to go
underground or through steel buildings. That
is not a failure. wi-fi routers take the GPS
signal and rebroadcast the timing element of it to minimize disruption."

and that "one of the core missions of the
Space Force is to protect and defend
America’s space assets, like GPS". If the

that is why the Department of Defense are in charge of it.
He added: "It's no overstatement to suggest
