  • EAB Q&A: GPS use in US infrastructure, PNT services

    EAB Q&A: GPS use in US infrastructure, PNT services

    GPS vulnerabilities have been widely reported in the press. What steps have been taken to back up GPS use in U.S. critical infrastructure?


    Jules McNeff
    Jules McNeff

    “President Biden on April 30 issued a National Security Memorandum on Critical Infrastructure Security and Resilience. GPS plays a vital role in the operation of critical infrastructure, and some sectors are considering their own backups. Other than conducting studies and meetings to admire the problem, the federal government has done virtually nothing to provide a comprehensive answer. In fact, the government is now dismantling the Loran system, though enhanced Loran (eLoran) is a viable and affordable GPS backup, specifically recommended for use by prior U.S. Department of Defense and U.S. Department of Homeland Security Deputy Secretaries. Given the vital role PNT and GPS play, it’s a mystery why such a viable solution is simply ignored.”

    Will GPS remain the Gold Standard of space-based PNT services for the foreseeable future?


    “GPS led the emergence and growth of a global space-based PNT service enterprise and has been the Gold Standard since its inception. The U.S. Department of Defense and Air Force (now Space Force) have maintained that standard through stable, transparent, and consistent policies and continuous performance improvements for the services it provides to all users. Now, in the face of foreign competition, hostile threats, budgetary pressures, reorganizations and management fragmentation, dilution of corporate memory, and inconsistent leadership support, those policy and performance foundations are in danger of eroding. The outcome for GPS and its future in the global PNT Enterprise is purely in the hands of our federal leadership today.”

    GPS integrity module
    Seamlessly integrates with existing platforms

    The Shift5 GPS integrity module is a platform-agnostic solution for military, aviation, rail, maritime and space applications.
    With real-time access and analysis of onboard data, the module assesses changes in navigational position through multi-faceted anomaly detection methods, which alert operators to GPS spoofing attacks as they happen.

    Using data collected from onboard systems, the module uses algorithmic position analysis to identify significant position deviations and GPS data validation to verify GPS information accuracy. Discrepancies or deviations that indicate tampering trigger an immediate notification, allowing operators to initiate standard operating procedures (SOPs) rapidly and accurately.

    The module is designed for cross-platform deployment, across commercial and military planes, locomotives, vessels and aircraft, as well as on other critical systems such as radar, unmanned aircraft systems (UAS) and weapon guidance systems. It seamlessly integrates with existing platforms and can deploy directly to onboard hardware.

    It offers multi-faceted detection and alerts for GPS spoofing attempts, designed to improve the safety and reliability of navigation systems. It uses physics-based spoofing detection to determine whether reported changes in position are physically possible to provide an effective method for initial spoofing detection. The system analyzes data from all sources to detect subtle, sophisticated spoofing attempts, which is essential for identifying more complex spoofing strategies that may evade traditional spoofing detection techniques.

    Shift5 alerts can be integrated into existing SOPs to help preempt contamination of other positioning and navigation data, such as inertial navigation calibration against false GPS data. Metadata about the time, location, duration and estimated position of the attack can be passed for inclusion in threat mapping and other geospatial systems for future route avoidance.

  • First fix: Trouble in orbit

    First fix: Trouble in orbit

    The solar storm in May that produced a beautiful aurora borealis as far south as Mallorca, Spain, also stopped GNSS-based precision agriculture for a couple of days. The same month, articles in major U.S. newspapers detailed aspects of a growing confrontation between the United States, Russia and China —vying for dominance in near-Earth space, now part of the military fighting domain — that could lead to far greater disruption. Nearly all satellites are highly vulnerable to cyberattacks, ground- or space-based lasers, high-powered microwaves, the debris field from a destroyed satellite and the radiation produced by a nuclear explosion in space. The last one would disable by far the greatest number of satellites because of its range and because commercial satellites, which constitute more than 90 percent of all satellites in orbit, are not hardened against such radiation.

    Matteo Luccio
    Luccio

    A May 16 article in The Wall Street Journal titled “Russia Launched Research Spacecraft for Antisatellite Nuclear Weapon Two Years Ago, U.S. Officials Say,” reported that in February 2022, shortly before it invaded Ukraine, Russia launched Cosmos-2553, “designed to test components for a potential antisatellite weapon that would carry a nuclear device.” It linked the launch to a continuing Russian nuclear antisatellite program and said that, if deployed, the weapon “would give Moscow the ability to destroy hundreds of satellites in low-Earth orbit (LEO) with a nuclear blast.”

    “The Pentagon,” the article pointed out, “has become increasingly reliant on commercial satellites.” In LEO, it reported, there are almost 6,700 U.S. satellites, while China has 780 and Russia only 149. Therefore, the Russians would have a lot less to lose should they choose to explode a nuclear weapon in LEO.

    A May 17 article in The New York Times was titled “New Star Wars Plan: Pentagon Rushes to Counter Threats in Orbit.” The subhead read: “Citing rapid advances by China and Russia, the United States is building an extensive capacity to fight battles in space.” It said that, in a major shift in military operations, the Defense Department “is looking to acquire a new generation of ground- and space-based tools that will allow it to defend its satellite network from attack and, if necessary, to disrupt or disable enemy spacecraft in orbit.” Meanwhile, “both Russia and China have already tested or deployed systems such as ground-based high-energy lasers, antisatellite missiles or maneuverable satellites that could be used to disrupt [U.S.] space assets.”

    The decision to strengthen U.S. warfighting capacity in space, it said, is driven mostly by China’s expanding fleet of military tools in space, which threatens to prevent U.S. Navy operations in the Western Pacific. “The Pentagon is separately working to launch a new generation of military satellites that can maneuver, be refueled while in space or have robotic arms that could reach out and grab — and potentially disrupt — an enemy satellite.”

    These are all reasons to quickly develop and deploy a wide mix of complementary PNT solutions that would lessen reliance on GNSS satellites and, therefore, make them less of a target.

    Every Monday and Wednesday, the team at Ernst Conservation Seeds gathers around maps to discuss which fields to harvest, which fields need treatments, and where to plant new crops.

    On this 10,000-acre farm near the small town of Meadville, Pennsylvania, the company pioneered the propagation of 180 species of native wildflowers, grasses, and wetland plants to revive degraded land and provide wildlife habitat.

    Now, the plants Ernst Seeds propagates are in high demand. Pollinator planting has become a trend worldwide, with the growing realization that flying bugs and birds are key to the survival of three-quarters of the world’s plants, including many we eat. Native plants are also being valued for nature-based solutions to protect soils from erosion and filter pollutants from stormwater.

    Across its operation, Ernst Seeds embraces the science of agronomy and the use of geographic information system (GIS) technology to understand native plant species and grow them better, faster, and less expensively.

    There’s a lot of experimentation that goes into growing native seeds and designing the right mix for each restoration project. “What we’re doing is going out and looking at existing plant communities to see what species grow together and how they’re doing it,” said Andy Ernst, vice president of Ernst Seeds. “Then there are lessons from our farming failures and successes. We make a lot of discoveries in our fields when we map yield data and the treatments we applied.”

    Improving plant propagation

    Typically, large farms focus on commodity crops like corn, soybeans, wheat, or cotton. At Ernst Seeds, the growing cycles of 180 species are tracked across 1,300 fields and 15 square miles.

    “I realized a long time ago that with the complexity of our farm, we needed software to track it,” Ernst said. His early forays into traditional farm management software products were frustrating as most could not support so many crops. The software lacked the data management and analysis capabilities needed to discern best practices for seed crops no one else was growing.

    Then in 2015, Ernst Seeds started using GIS. For operations, the ability to see fertilizer and spray assignments on smart maps helped the company identify places that required more or less treatment.

    “There are a lot of accidental experiments when a row is skipped, there’s overlap, or a different chemistry is used,” Ernst said. “When we go out in the field, we can see areas that thrive and other areas that do poorly. With GIS, we can answer why.”

    Katy Flaherty, an agronomy expert and the GIS manager at Ernst Seeds, developed a GIS-powered work order management system that guides each phase of production, from planting and fertilizing to applying pesticides and harvesting. The system uses a combination of ArcGIS Survey123ArcGIS Field Maps, and ArcGIS Dashboards to record data and visualize trends. Flaherty also uses ArcGIS Pro to analyze data from the field, layering it with historical crop records and real-time soil and weather data to uncover correlations.

    “When we plan our fields across four counties, there are significant differences in what crops do well from north to south,” Flaherty said. “It’s very spatial aware farming, and that knowledge transfers to recommendations for customers.”

    In one instance, this detailed level of monitoring led to a decision to stop using a product that harmed some plants. In another case, improvements in propagation for a species proved so fruitful that smaller plots would meet the demand.

    Smart maps guide the company’s planting locations, irrigation system maintenance, and harvesting schedule. Staff use smart maps to track plant maturity and time seed harvests. Unlike corn and soybeans, which can sit in fields for months, some native seeds have only three days of viable harvest. Knowing when and where to harvest is crucial. Ernst Seeds sells 70% of the seeds it harvests every year, putting the rest in the ground for the next crop cycle.

    Filling gaps and expanding geographic reach

    Calvin Ernst, Andy’s father, started the thriving conservation seeds business in 1964 with a Pennsylvania Department of Transportation contract to supply seeds to revegetate highway rights-of-way. Over the next 50 years, the company made wild seed collecting forays across the US to add plants to its offerings. As species count and seed supply grew, so did work with a broader list of customers, including state and federal agencies.

    The company has developed seed mixes tailored to specific regions, such as Maryland, northern Virginia, and coastal North Carolina. These seeds are adapted to thrive in the local weather and soil. By choosing native seeds, restoration project managers ensure plants are well-suited to the ecosystem and more resilient to changing climate conditions.

    “A simple philosophy is to avoid plants in your seed mixes that would be planted at the southern edge of their historical range,” Ernst said, speaking to the growing need for heat-adapted plants.

    This commitment to innovation comes at a cost—it takes time to establish every new species. But insights from GIS can accelerate that timeline.

    “It can take seven to 10 years to figure out how to grow something,” Ernst said. “If our observations cut that time down to five years, that’s a major win for us.”

    Building native seeds capacity

    One of the main challenges with native seed farming, according to Ernst agronomists, is the lack of knowledge of native seed production when compared to conventional row crops.

    While the company has typically filled knowledge gaps itself, there have been times when an academic partnership has proved beneficial. For example, Ernst Seeds collaborated with researchers at the Center for Pollinator Research at Pennsylvania State University to identify the mix of flowering plants that could maximize pollinator food and breeding opportunities. The seed mixes developed through this partnership are now used across solar energy farms for revegetation.

    The work on developing the right seed mix for solar farms made Ernst Seeds an ideal partner for the Virginia Solar Pollinator Program. Originally, Ernst Seeds was employed on the project by the Virginia Department of Conservation and Recreation to guide a mix of native seeds for Virginia, but that work expanded.

    Ernst Seeds experts then worked alongside the Clifton Institute to gather seeds across Virginia, from the Coastal Plain to beyond the Blue Ridge Mountains. They recorded the location and conditions of their findings using a GIS-powered mobile app on their phones. This knowledge will help in planting along corridor projects, such as land beneath the electric transmission lines that will deliver energy from solar farms in rural areas to businesses and households in urban centers.

    From its start with solar projects, the program evolved into the Virginia Native Seed Pilot Project to launch a native seed industry in Virginia. The program identifies local growers who can produce native seeds at a commercial scale and shows them how data from GIS helps guide best practices.

    “Creating a GIS-centric culture at Ernst has changed how managers and operators work the fields,” Flaherty said. “We aren’t only looking at maps and numbers, we’re utilizing and making the data work for us every day.”

    A data-driven approach to farming can be tough to instill in farmers working the same fields with the same approach for decades.

    “Early on, we had pushback about the need to collect different information,” Ernst said. “Then in one meeting, we had a big lights-come-on moment when the answers we needed came from the data they’d been collecting. The guys were saying, ‘I know what we did there,’ but when we looked at the records their memory wasn’t as good as they thought it was.”

    In a recently released paper, the respected analytics firm London Economics determined that the presence of backup systems at the Denver and Dallas Fort Worth airports prevented any noticeable impacts on air travel despite each having experienced a disruption of GPS signals for 24 hours or more. By contrast, recent GPS interference at an airport without a backup system caused scheduled air service to be canceled until an alternative to GPS was established.

    Also important to the lack of impact at Denver and Dallas was that the signals interfering with GPS, with a few minor exceptions, only impacted aircraft in the air.

    GPS is essential for the safe and efficient movement of aircraft and support vehicles on the ground at airports, as well as the transport of crews, passengers, supplies, and cargo to and from airports, communication systems, and numerous other services.

    Backups needed for both air and ground

    Previous work by London Economics has shown that disruption of GPS for these ground functions would likely cause numerous flight delays and cancellations. Delays in the arrival of flight crews, passengers and supplies, for example, would quickly upset flight schedules. If this happened at a major airport, such as Denver or Dallas Fort Worth, disruptions could ripple through the entire air transport system. Wide-spread delays, cancellations and schedule adjustments would bog down air travel across the nation, if not the world.

    The incident in Denver was caused by an accidental transmission from a government installation on Jan. 21. 2022. It impacted aircraft within approximately 50 nautical miles of the airport and lasted 33 hours before the source was identified and turned off.

    The Dallas incident began on Oct. 17, 2022, and affected aircraft within about 110 nautical miles. It continued for 24 hours before ending on its own. The source has never been identified.

    Reducing aviation backups may be a bad idea

    In addition to recognizing the value of terrestrial navigation systems for aviation, the London Economics paper cautions about moves in the United States and Europe to “rationalize” these systems by reducing their number. In the event of longer or widespread GPS disruptions, the impact of an insufficient number of terrestrial systems could be significant. The cancellation of air service to an airport in Estonia because of chronic GPS jamming is used in the paper as a cautionary tale.

    Instead of reducing the number of old backup systems, London Economics suggests policymakers consider establishing more widely available sources of terrestrial PNT. Taking a fresh look might identify alternative PNT sources for aviation that could also be used by other critical infrastructures. Perhaps even in consumer applications as well.

    U.S. government representatives were approached for consultation and comment for this paper and expressed their willingness to participate. Unfortunately, they were unable to obtain permission to do so.

    London Economics’ work on this effort was commissioned by the Resilient Navigation and Timing Foundation.
