Whereas serving on the Nationwide Safety Council employees within the Biden administration, I used to be tasked with strengthening the resilience of U.S. vital infrastructure, specifically its reliance on GPS for positioning, navigation, and timing (PNT) programs. With little funding or congressional help, I proposed integrating China’s BeiDou satellite tv for pc navigation system as a backup for civilian use to reinforce redundancy and interoperability throughout the non-public sector, together with in vital infrastructure. The proposal raised eyebrows. Over time, nonetheless, it gained traction with key stakeholders throughout the chief department, together with the Nationwide Safety Council, the Nationwide Area Council, the Cybersecurity and Infrastructure Safety Company, and the Division of Transportation. Sadly, the administration’s time in workplace ended earlier than I may carry the proposal to a broader group of businesses for assessment and approval. A brand new alternative might now be on the horizon.
The USA depends closely on GPS for PNT help. GPS permits numerous facets of our each day lives, from banking to air journey, to electrical energy. This dependence is a vulnerability, as GPS alerts are simply jammed or spoofed and could possibly be focused by adversaries. Whereas the first Trump administration did acknowledge the necessity to strengthen PNT resilience, it narrowly targeted on bolstering U.S. programs or utilizing pleasant options.
It’s time the US look past such typical measures.
Integrating China’s BeiDou system as a backup PNT system for civilian utility can increase resilience, interoperability, and deterrence. Regardless of the perceived threat to nationwide safety, bringing BeiDou into the fold is each sensible and possible.
Strengthening PNT Resilience: Standard Measures
The U.S. authorities and non-public corporations have pursued a spread of methods to bolster PNT resilience. In area, the US is modernizing GPS satellites with extra sturdy, jam-resistant alerts and higher cybersecurity protections. On the bottom, analysis is underway into terrestrial backup programs — from resurrecting low-frequency radio navigation to new land-based transmitters and fiber-optic timing networks. The Division of Homeland Safety, for its half, makes use of a “Defend, Toughen, and Increase” mannequin: shield GPS alerts, toughen receivers towards spoofing, and increase GPS with complementary sources. Notably, different main powers have already applied such multi-layered resilience. China and Russia have deployed terrestrial PNT programs to enrich their satellite tv for pc constellations, creating layered backups that the US presently lacks. This multi-layered strategy guards towards a single level of failure disrupting vital PNT companies.
Europe’s Galileo: Interoperability and Shared Dangers
The European Union has constructed Galileo, its personal world navigation satellite tv for pc system. In 2018, the U.S. Federal Communications Fee formally approved U.S. units, together with vital infrastructure sectors, to entry Galileo alerts alongside GPS. The rationale was clear: Combining GPS and Galileo improves positioning availability, reliability, and resilience for customers. Interoperability agreements guarantee Galileo’s alerts are largely suitable with GPS, enabling units to routinely and transparently choose the strongest satellite tv for pc sign with out the consumer even realizing.
Crucially, Galileo, like GPS, will be jammed or spoofed by malicious actors utilizing comparatively cheap tools, since each programs broadcast in identified frequency bands. Russian digital warfare has disrupted GPS alerts throughout Scandinavia. Such an assault would equally blind Galileo receivers in the identical bands. Whereas Galileo enhances civilian reliability, its shared vulnerabilities with GPS underscore the necessity for extra diversification.
GPS: The Spine of U.S. Essential Infrastructure
The GPS constellation comprising 31 operational satellites stays the inspiration of U.S. vital infrastructure. Its exact timing and ubiquitous positioning capabilities have been built-in into each vital infrastructure sector. Every day actions like withdrawing money, pumping gasoline, or routing an ambulance depend on the timing and site information that GPS gives. This reliance creates a vulnerability that may be exploited by a technologically savvy adversary. Thus, pressing motion is required to diversify PNT sources to safeguard U.S. nationwide safety.
Integrating China’s BeiDou into U.S. PNT Methods
The USA ought to diversify its PNT sources past GPS, regardless of considerations that counting on options like China’s BeiDou may expose the US to potential coercion or blackmail. The U.S. authorities, by way of the Nationwide Safety Council and the Cybersecurity and Infrastructure Safety Company, ought to authorize the non-public sector and direct vital infrastructure house owners to combine China’s BeiDou navigation satellite tv for pc system alerts into U.S. business and civilian PNT architectures. BeiDou is a completely operational world navigation constellation as of 2020, with 45 satellites in orbit. It affords positioning and timing accuracies akin to GPS, and China has invested closely in system redundancy and reliability. U.S. officers acknowledge that China’s PNT capabilities have grown impressively: Federal Communications Fee Commissioner Nathan Simington just lately cautioned that GPS vulnerabilities mixed with the rising energy of BeiDou is “turning into considered one of America’s greatest safety points.”
Technical Feasibility
Incorporating BeiDou for U.S. civilian use is technically possible. Fashionable International Navigation Satellite tv for pc System machine chipsets are sometimes constructed to be multi-constellation — which means a single machine can obtain and course of alerts from GPS, Galileo, Russia’s GLONASS, or China’s BeiDou. Many U.S. smartphones already do that with out the consumer realizing it. Main handset producers together with Apple, Google, and Samsung have produced telephones that routinely use BeiDou and GLONASS along with GPS to enhance accuracy, though Federal Communications Fee guidelines solely explicitly enable GPS and Galileo alerts.
From a {hardware} standpoint, including BeiDou functionality to receivers in vital infrastructure (say, telecom networks or energy grid timing items) would contain upgrading firmware or swapping in available multi-International Navigation Satellite tv for pc System machine modules. The open civilian BeiDou alerts (generally known as B1 and B2 frequencies) are publicly documented and accessible with no proprietary expertise or secret key wanted to make use of them. Regulatory changes can be the primary hurdle — like how the Federal Communications Fee issued a waiver in 2018 to permit Galileo’s use for U.S. programs together with vital infrastructure. The Federal Communication Fee would want to explicitly allow BeiDou sign utilization by U.S. units. It is a coverage query, not a technical one. The course of for certifying Galileo concerned the European Fee requesting a waiver by way of the Nationwide Telecommunications and Data Administration in 2013, adopted by a public remark interval and Federal Communication Fee approval in 2018. Equally, the Chinese language authorities may request a waiver for BeiDou, or the U.S. authorities may unilaterally grant one, and, following established precedent, combine it with acceptable regulatory steps.
In reality, efficient authorities laws may deal with the inclusion of BeiDou by setting clear requirements for multi-International Navigation Satellite tv for pc System integration. For instance, underneath Nationwide Safety Memorandum 22, sector threat administration businesses are tasked with establishing minimal safety and resilience necessities for vital infrastructure, together with PNT programs. This gives flexibility for federal businesses and infrastructure house owners to handle resilience whereas making certain compliance with minimal requirements. With clear guidelines of use, the non-public sector may quickly combine BeiDou for personal use together with into vital infrastructure and industrial GPS receivers, successfully unlocking a complete second constellation for America’s PNT wants at minimal price.
Resilience and Redundancy Advantages
The first argument for embracing BeiDou is the numerous increase to redundancy. Merely put, extra satellites from an impartial system means extra possibilities that important PNT companies stay out there when GPS is degraded. If GPS had been to go offline unexpectedly — whether or not resulting from a cyber incident, satellite tv for pc malfunction, or hostile motion — a tool configured to make use of BeiDou may instantly fall again to the Chinese language alerts to keep up connectivity. This “sizzling backup” could possibly be the distinction between a nationwide outage versus a minor disruption in service. There’s already priority. When Galileo went out for six days in 2019, customers barely seen as a result of their units seamlessly reverted to GPS. In a potential future situation through which GPS turns into compromised, having BeiDou enabled would enable the reverse: U.S. programs may lean on the Chinese language constellation till GPS is restored.
Utilizing a number of constellations additionally improves machine efficiency. Units that mix GPS and BeiDou have entry to almost twice the variety of satellites in area, which yields extra sturdy protection in difficult environments reminiscent of city canyons. This improved sign range interprets to raised accuracy and reliability for all civilian functions — a direct public profit. It additionally gives a test towards sure types of assault: A complicated spoofing try (the place a malicious transmitter mimics GPS alerts to deceive receivers) must idiot a number of constellations concurrently if the machine is cross-checking GPS towards BeiDou. In follow, that’s far harder to perform. Nonetheless, anticipating particular person customers to manually deal with spoofing alerts is unrealistic. Luckily, fashionable world navigation receivers can make use of superior strategies like Kalman filtering to routinely detect and mitigate spoofing by cross-checking information from a number of constellations. This ensures that if one system is compromised, the machine can preserve accuracy utilizing one other system. This dual-constellation strategy strengthens PNT safety and reliability for all civilian functions together with vital infrastructure.
Strategic Rationale and Deterrence
Past the technical deserves, there’s a compelling strategic case for multi-constellation integration that includes an adversary’s system. At present, U.S. protection planners fear {that a} decided opponent like China may degrade American capabilities by focusing on GPS, its single level of failure, on the outset of a battle. This vulnerability creates a temptation for a Chinese language first strike towards GPS satellites or widespread jamming of GPS alerts. If, nonetheless, the US has included BeiDou into its PNT ecosystem, the calculus for an adversary may change. By entangling U.S. programs together with vital infrastructure with Chinese language owned navigation programs, it might introduce a type of mutual assured PNT stability. China would know that disrupting GPS alone may not be sufficient to noticeably have an effect on U.S. vital infrastructure: American programs may hold working on BeiDou alerts (or Galileo’s) for a while.
Whereas integrating Galileo as a backup creates redundancy, integrating BeiDou additionally yields a robust deterrent impact because it entails a possible adversary’s system. Against this, since Galileo is operated by U.S. allies, it’d enchantment as a goal in a possible United States-China battle, whereas integrating BeiDou implies that disrupting GPS wouldn’t absolutely obtain an adversary’s objectives, as U.S. programs may nonetheless perform utilizing BeiDou. Furthermore, any try by China to disable BeiDou alerts over the US (as an illustration, by geo-fencing, which creates digital boundaries to limit or management satellite tv for pc sign entry in particular areas, or degrading service in a disaster) would undercut its personal system’s reliability and will invite retaliation. In impact, incorporating BeiDou alerts would function a type of deterrence by denial: It denies an adversary the fast, decisive impression it seeks by attacking GPS, thereby discouraging such an assault within the first place.
Addressing Nationwide Safety Issues
Integrating a competitor’s expertise right into a U.S. system understandably raises eyebrows. Some might fear that counting on BeiDou may expose the US to hidden dangers. May China manipulate the alerts to mislead the U.S. authorities or spy on People? The quick reply is “no.” Like GPS, the civilian BeiDou alerts are one-way radio broadcasts of time and satellite tv for pc place. They don’t carry command hyperlinks into U.S. receivers and utilizing them doesn’t transmit information again to China. In different phrases, utilizing BeiDou doesn’t enable China to “spy” on a U.S. machine — the movement of knowledge is just from the satellite tv for pc to the end-user.
The first concern with respect to U.S. nationwide safety and BeiDou can be sign authenticity: May China transmit false information or stop transmission in a disaster? These eventualities, whereas believable, will be mitigated. Multi-constellation receivers can validate one constellation towards one other, so any evident inconsistency — for instance, if BeiDou instantly began giving time or location information that diverged wildly from GPS or Galileo — can be flagged. Methods could possibly be coded with directions that if BeiDou information appears maliciously corrupted, they will merely dismiss it and use different sources as a substitute. If China selected to show off BeiDou totally for strategic causes, reminiscent of to realize a navy benefit or geopolitical leverage, it might deny U.S. customers entry to its satellite tv for pc navigation alerts. This loss would solely scale back the improved positioning and timing accuracy that U.S. customers acquire when combining BeiDou with GPS. Thus, utilizing BeiDou’s open sign carries little draw back past what U.S. customers already face with GPS. Furthermore, there’s precedent for balancing nationwide safety and enhanced entry: A Federal Communications Fee’s inquiry highlighted that many U.S.-based telephones have accessed BeiDou/GLONASS, and it sought enter on potential vulnerabilities. By approaching integration intentionally — by way of certifying units that use international alerts solely in tandem with trusted ones and with sturdy interference detection — the US can decrease threat whereas reaping the resilience advantages.
Lastly, incorporating BeiDou for civilian resilience needn’t weaken the U.S. dedication to making sure GPS stays the world’s predominant supply of PNT companies. The U.S. navy will proceed to view GPS because the gold normal for assured PNT in battle, and growing purely U.S. backups — like superior terrestrial programs or small satellite tv for pc constellations — stays necessary. Incorporating BeiDou into U.S. units gives a strategic buffer and added resilience as the US strengthens its personal programs. Many U.S. allies and companions already use multi-International Navigation Satellite tv for pc System units: Industrial airways and container ships routinely use GPS, Galileo, and BeiDou collectively for finest efficiency. By becoming a member of different nations that already do that, the US would improve worldwide interoperability. In a catastrophe response situation, for instance, U.S. and Chinese language civilian groups may function on frequent navigation references if each are utilizing each programs. This interoperability enhances world coordination in civilian functions, enabling nearer multi-International Navigation Satellite tv for pc System cooperation with companions just like the European Union, Japan, and Australia.
Pragmatism Over Worry
As the US grapples with how one can enhance PNT resilience, pragmatism ought to prevail over apprehension and worry. GPS will stay very important for nationwide safety and financial exercise, which underscores the necessity for the US to diversify its resilience. Utilizing China’s BeiDou alerts in U.S. civilian PNT programs is a sensible step — it makes use of current infrastructure to reinforce safety and stability. Integrating BeiDou may incentivize a type of PNT détente between the US and China, the place either side is aware of the opposite has options, lowering the temptation for reckless interference. Moreover, Nationwide Safety Memorandum 22 underscores the significance of resilience in vital infrastructure. It duties sector threat administration businesses with establishing minimal safety and resilience necessities for his or her respective sectors. For sectors reliant on PNT, reminiscent of transportation and communications, integrating a number of programs, together with BeiDou, could possibly be a sensible technique to meet these resilience mandates whereas leveraging current world infrastructure.
Resilience in vital infrastructure typically comes from redundancy and variety. Simply because the U.S. electrical grid advantages from a number of energy sources, U.S. digital infrastructure ought to draw from a number of navigation constellations. By rigorously integrating BeiDou for civilian and business use, alongside GPS and Galileo, the US would take an enormous, daring step towards future-proofing its PNT companies. This transfer would increase alerts resilience and flexibility, making certain sturdy PNT companies even underneath disrupted or degraded circumstances. Such a technique embodies an authoritative but accessible reality for nationwide safety planners — redundancy is a energy, and typically which means embracing an surprising companion to safe the nation’s very important pursuits.
