But
the new systems’ more advanced capabilities are hard to ignore. Future
makers of smartphones, vehicles and industrial equipment might decide to
stop using GPS by default and start relying on Chinese signals first,
for instance.
“There’s
some inertia in being able to modernize GPS,” Betz says. “It doesn’t
get to start with a blank sheet of paper.” The U.S. plans to keep using
GPS’s original radio frequency, for instance—even as it adds new
channels—to avoid making billions of dependent devices obsolete.
The
Space Force said in a statement that GPS continues to set the gold
standard in its field. “While other nations may report improvements in
accuracy and equivalent performance in availability, GPS is still the
clear leader in integrity and is the only system accepted for
international flight use,” a spokeswoman for the branch’s Space Systems
Command said.
U.S. plans
The
U.S. military has long planned to upgrade GPS with a fleet of modern
and upgradable satellites that provide more-precise coordinates subject
to less interference. The newer satellites broadcast data to civilian
users over a new frequency called L5.
The Space Force has 17 L5-equipped satellites in orbit after a spate of delays
but has yet to reach the 24 live satellites needed to run a reliable
system. Some already-built satellites sit in a Colorado warehouse
awaiting their turn for a funded launch.
A
Space Force spokesperson says the system with newer frequencies will
keep growing and will be fully operational by 2027. Another fleet of
satellites is slated to go live in the 2030s. A 2021 Government
Accountability Office report estimated the two core satellite upgrades together would cost more than $15 billion.
The
slow rollout worries Mark Montgomery, a retired Navy rear admiral who
leads the federally chartered U.S. Cyberspace Solarium Commission, a
group tasked with developing defenses against potential cyberattacks. He
cites the civilian industries that rely on GPS, from seaport cranes to
cellular networks, as a blind spot for American defense officials.
“Here’s
this system that is absolutely vital to our critical infrastructure and
we have almost no resiliency, and in fact the U.S. system is starting
to decay,” Montgomery says. He urged the Space Force to fast-track its
future launches.
Lockheed-Martin,
which built the four satellites in storage, says one is already slated
to launch in mid-2024. Program management director Juli Best says the
company built a suite of new features into the satellites and
streamlined its production processes “to help us enhance and deliver GPS
faster,” adding that the defense contractor “is prepared to support the
U.S. Space Force’s planned cadence of GPS launches.”
