Both China and Russia also recognize GPS’ and PNT’s role in “hard power.”

Signal jamming

China has regularly jammed GPS signals in the South China Sea as part of its illegal extraterritorial claims around the Spratly Islands. And it has regularly spoofed, or sent false GPS signals, to conceal the real locations of ships. This was most likely in an effort to avoid sanctions for importing Iranian oil.

Russian forces in Ukraine regularly jam GPS signals to degrade the effectiveness of US-provided precision weapons and defeat drone attacks. And just before the war began Russia destroyed a retired satellite boasting it could “shoot down all 32 GPS satellites and blind NATO.” A threat taken seriously by the White House, according to a National Security Council official who described GPS as “a single point of failure” for the nation.

Observers have questioned what impact this threat has had on America’s response to the invasion and on-going conflict.

China’s and Russia’s threats to GPS are particularly of concern because both those nations have national terrestrial alternatives to GPS and GPS-like systems while the U.S. does not. Thus, if either nation were to seriously disrupt GPS, the U.S. would not be able to achieve the same impact by responding in kind. This disparity between capabilities is seen by some analysts as ripe for exploitation, something that could lead to an escalating series of responses and a shooting war.

To address these challenges the Advisory Board recommends the administration “…convene a White House summit celebrating U.S. achievements with GPS and launch new era of innovation and prosperity.” The event should have three goals, it says.

Critical infrastructure

First, to raise public “…awareness of GPS’ contributions and importance to America and the world.” While most people understand that GPS is based on satellites and helps them navigate, few, including policy makers, understand the key role it plays in supporting virtually all technologies and critical infrastructures.

The summit should also lead to improvements in the way GPS and PNT efforts are led within the government with appointment of “…a senior responsible official.” Leadership is currently vested in a very senior cross-department committee that advises the Executive Office of the President. The committee rarely meets, and its senior co-chairs have not participated in decades. Observers have often commented that a critical national capability like GPS and PNT must have focused, day-to-day senior leadership.

Finally, the board says, the summit should “Lead to implementation of a systems approach to a resilient national PNT architecture to underpin national security and economic prosperity.”

This, experts say, would involve establishment of services that worked with GPS and provided similar information, but from different sources and by different methods. Time signals from the National Institute of Standards and Technology could be delivered by fiber and terrestrial broadcast, for example. Navigation information to complement GPS could be provided by terrestrial broadcasts. Satellites orbiting closer to the earth and less susceptible to interference than GPS could also be part of the solution.

None of these technologies are new, and all are relatively inexpensive. The only thing needed, according to many experts, is government focus and leadership.

The alternative is for the U.S. to continue falling behind China and others in area in which it has led the world for over fifty years. This would also perpetuate significant risks to national and economic security.

The administration has not yet responded to the Advisory Board’s January recommendation, nor its May white paper. Sources say a response is being coordinated and should be available before the board meets again in December.
