  • PNT Executive Order helpful, but delays market solutions

    PNT Executive Order helpful, but delays market solutions

    Headshot: Dana Goward
    Dana Goward, President, Resilient PNT Foundation

    On Feb. 12, the White House released an “Executive Order on Strengthening National Resilience through Responsible Use of Positioning, Navigation, and Timing Services.”

    It is gratifying to see White House attention to this issue. The increase in public awareness it brings will benefit individual users and the nation as a whole.

    The order also hints at market driven solutions that could quickly improve America’s PNT resilience.

    Needless delays

    Unfortunately, the order fails to direct immediate action on this critical national and economic security issue. Instead it needlessly pushes most action and responsibility off for a year or more to do “more study.”

    This is hard to understand as most of the “more study” has already been completed. For example, the order tells the Department of Commerce to take up to a year to examine PNT use in various sectors, and identify vulnerabilities and user needs. The Department of Homeland Security has already completed a National Risk Assessment and, according to congressional staff, has recently completed a report on user requirements mandated in 2017’s National Defense Authorization Act.

    The Office of Science and Technology Policy is given a year to develop a plan to test robust and resilient non-GNSS PNT services (but is not required to actually do any testing). Congress mandated such a test program in 2017 and funded it with $10 million in 2018. After much delay, the Department of Transportation will complete the testing in May of this year.

    The order gives the Department of Commerce six months to make available a time source to support critical infrastructure. For more than 60 years, the nation’s master clock has been available to users at the department’s NIST Laboratory in Boulder, Colorado.

    Note the challenge has not been the clock, but that the nation has no way — other than vulnerable GPS signals — to distribute time at the needed level of accuracy to millions of critical infrastructure nodes. Government studies in 2007 and 2014 determined that the best way to do this was with a ground-based system. The Department of Transportation’s ongoing testing program is examining this issue again.

    Market-driven solutions

    Aside from increasing public awareness, the best thing the Executive Order does is to point a way forward for market-driven resilient PNT solutions.

    The order calls for federal contracts to (in 21 months, if everyone does their jobs on time) require that vendors use existing and new resilient PNT sources.

    If this eventually happens, the government could leverage its enormous influence in the market and stimulate creation of one or more commercial distribution systems for resilient, non-GNSS PNT. This is a great concept, and very much in keeping with America’s tradition of letting market forces solve some of its biggest problems.

    But this solution will not spring into life on its own.

    No commercial entity will invest tens of millions of dollars, or more, in a PNT system without assurance in advance of an income stream. Especially since federal contracting officers can and will waive the requirement if offerors cannot reasonably meet it.

    If stimulating a market solution is the administration’s intent, it must stay actively involved and encourage the process for some time to come.

    This includes complying with the 2018 law that requires establishment of at least one wireless, terrestrial, difficult-to-disrupt source to back up the timing signals provided by GPS.

    Fortunately, this can be done by leveraging the free market at minimal cost and with little administrative effort.

    By contracting to subscribe to a commercial service that will provide resilient PNT signals, the government need only invest a relatively small yearly sum using a fairly simple contract vehicle. Such a contracting technique has been used before with great success.

    In 2007 the Federal Aviation Administration (FAA) did this as a way to establish its ADS-B aviation tracking and safety network. Once the subscription contract was let, the commercial provider was able to get financing and quickly build out the system.

    Today, the FAA gets the information it needs, doesn’t have the headache of owning and maintaining a large network, and even shares in the revenue the system owner earns from selling data to other companies.

    Additional leadership needed

    It is important to remember that, regardless of the issue, presidential pronouncements are not enough.

    In 2004, President G.W. Bush directed a number of actions to protect the nation’s critical PNT, including establishment of a GPS backup capability. While 16 years later his directive is still official executive branch policy, that mandate and many others from his order are still unexecuted.

    Real improvements to PNT resilience and our nation’s security depend not on one-time pronouncements, but continued leadership focus and engagement.

    This is always a challenge for initiatives driven by the White House. It will be doubly so in this case as there is no clear department leader for civil PNT issues the administration can rely on while it attends to the next issue of the day.

  • Executive Order requires resilience of critical PNT infrastructure

    Executive Order requires resilience of critical PNT infrastructure

    On Feb. 12, President Donald Trump signed an Executive Order establishing a comprehensive national policy to promote the responsible use of positioning, navigation and timing (PNT) services by the federal government.

    The order directs federal agencies to take steps to reduce disruption of critical infrastructure that relies on PNT, including GPS. It also directs critical infrastructure owners and operators to strengthen their systems’ resilience.

    Markets affected include including the electrical power grid, communications infrastructure and mobile devices, all modes of transportation, precision agriculture, weather forecasting and emergency response.

    The federal government will engage both the public and private sectors to identify and promote responsible use of PNT services, with the goal of ensuring that “critical infrastructure can withstand disruption or manipulation of PNT services.”

    “Because of the widespread adoption of PNT services, the disruption or manipulation of these services has the potential to adversely affect the national and economic security of the United States,” the order states. “To strengthen national resilience, the Federal Government must foster the responsible use of PNT services by critical infrastructure owners and operators,” the order reads.

    PNT Profiles

    The Commerce Department is tasked with developing PNT profiles, due a year from today, for PNT-dependent  systems, networks and assets. The profiles will be developed through consultation with the private sector.

    The profiles will also:

    • identify appropriate PNT services;
    • detect the disruption and manipulation of PNT services; and
    • manage the associated risks to the systems, networks and assets dependent on PNT services.

    The profiles will be reviewed and updated every two years.

    Reaction to the Order

    Reacting to the Executive Order on PNT,  J. David Grossman, executive director of the GPS Innovation Alliance (GPSIA), stated:

    “The GPS Innovation Alliance (GPSIA) welcomes today’s Executive Order recognizing the critical economic and societal benefits of GPS and other Global Navigation Satellite Systems (GNSS). Resiliency is among the core attributes that have made GPS the gold standard for delivering positioning, navigation, and timing (PNT) functions to our military as well as a wide range of other sectors, including transportation, agriculture, electricity, and finance. Today’s Executive Order represents a crucial next step in ongoing efforts to maintain the security, robustness, and redundancy of PNT capabilities, including GPS, that millions of Americans rely on every day. GPSIA looks forward to working with key government stakeholders to support the implementation of this effort.”

    The Department of Transportation stated,

    “Our challenge is to enable increased resilience across our transportation systems and ensure the traveling public and freight transporters experience an increased level of safety and efficiency without the possibility of interference caused by loss or manipulation of PNT.

    Department of Homeland Security Acting Secretary Chad F. Wolf said,

    “From mobile phone applications to automobile navigation, our digital, interconnected society is dependent every day on PNT services.That is why it’s critically important that PNT services remain properly functioning as a major component of the nation’s critical infrastructure. By adopting responsible use of PNT services, the federal government and owners and operators of critical infrastructure can contribute meaningfully to national resilience and ensure the continuous, uninterrupted delivery of services to the nation.”

  • Working together for a more navigable world

    Working together for a more navigable world

    “Diverse teams bring diverse ideas to the table, and that’s the best way to progress.”

    So said Professor Sheila Rowan, the UK government’s chief scientific advisor to Scotland, opening the Royal Institute of Navigation’s 2019 International Navigation Conference. Professor Rowan’s comments set the scene perfectly. Success in navigation is no longer about just getting a fix, or even an accurate fix. To succeed as a system or application provider, diversity and collaboration are key, whether it be multiple disciplines and the skills that go with them, or a mix of ages, beliefs and backgrounds. So, what were some key messages to emerge from four days of working together?

    More practical help for non-experts wanting to improve resilience in positioning, navigation and timing (PNT) is needed. The top request from delegates at the pre-conference short course was for more detailed and specific information on threats to PNT. Of particular interest were how to measure the impacts and test the merits of various mitigation approaches. In other words: how to assess risk? How to decide what steps to take?

    User acceptance and regulatory/legal structures for driverless vehicles are greater challenges than the positioning and communications technology. In the UK and across Europe, projects are under way to evaluate good practices for so-called “beyond line of sight” drone flights. For driverless cars, while huge strides have been taken to enable secure and resilient absolute and relative positioning, much remains to be done. Practical issues were highlighted, such as over-cautious vehicles and a tendency for driverless cars to make occupants feel more travel sick. So work needs to be done to avoid a stressfully slow and sickly experience.

    Skills and knowledge are changing — and education/training needs to, too. A major developed-world problem is that the experts with experience who have seen generation after generation of technology evolution are now in their later careers or retired. Because of the wealth of knowledge vested in these individuals — we can all think of some, I’m sure — organizations have tended to over-rely on them. A key theme of the conference closing plenary was that the community wants to do more to collaborate — that word again — to define training needs and figure out how to deliver the skills that are needed today and tomorrow.

    The next couple of years bring fewer, bigger navigation conferences in Europe. The European Navigation Conference (ENC) 2020 takes place in Dresden, May 11–14, organized by the German Institute of Navigation, DGON. ENC2021 will be combined with the triennial global congress of the International Association of Institutes of Navigation (IAIN), Nov. 15–18, 2021, in Edinburgh, organized by the Royal Institute of Navigation.

    Please save the dates — joining these events is rewarding and stimulating as we work together toward a more navigable world.

  • Staying ahead of NAVWAR and resilient PNT in 2020

    Staying ahead of NAVWAR and resilient PNT in 2020

    Image: Orolia

    Year-End Message from Orolia

    In 2019, military forces witnessed the global threat of GPS/GNSS interference grow, with more sophisticated threats and increasing military demand for assured operations in Navigation Warfare (NAVWAR) and GPS-denied environments.

    Enemy forces are deploying more advanced jamming and spoofing technologies worldwide, jeopardizing the security and reliability of positioning, navigation and timing (PNT) data that feeds into GPS receivers, downstream networks and subsystems.

    Military forces must vigilantly protect their information advantage from malicious attacks by delivering situational awareness, mission planning and warfighter solutions.

    For these priorities, proven and efficient signal integrity solutions will be even more critical in 2020.

    Requirements to Ensure Signal Integrity in 2020

    Any critical system that relies on PNT data should go into the field with two known states:

    • First, it should withstand a GPS outage during testing and simulation — including rigorous jamming and spoofing simulation to predict how the system will react under various conditions. Simulation scenarios can vary in complexity, and newer software-defined simulators provide flexibility to meet current requirements while future-proofing investments in test equipment.
    • Second, the system should have a signal threat detection and alert mechanism. Critical systems also need backup layers such as anti-jam antennas, threat mitigation technology and alternative encrypted signals to ensure continuous operations, even in compromised environments.

    Going into 2020, GNSS simulation and interference detection and mitigation (IDM) will continue to adapt to emerging threats and provide the essential foundation for Assured PNT.

  • What resilient means for defense applications

    Virtually all defense and security applications of GPS/GNSS require additional technology to protect assets and missions against signal interference, whether jamming or spoofing. The upcoming free webinar, Resilient PNT for Military Applications, gives a primer on several of these technology options. Mitigation in this context means that after isolating the unwanted signal, quickly rejecting and replacing it, causing minimal system degradation. In essence, this involves the use of augmentation technologies and diversification strategies to supplement GPS/GNSS, thus reducing the dependence on it.

    Applications relevant to this approach include:
    Airborne: Observation payload (radar, optronics, electronic warfare), flying test bench, flight analysis, tactical UAV navigation;

    Ground: Blue Force tracking, vehicle navigation, satcom on the move (SOTM), Anti IED jamming systems, mobile radios and C4ISR, robotics;

    Marine/Naval: Sensor support (radars, sonars, optronics, electronic warfare), communication networks, offshore/DSO platform.

    Possible sources of such additional technology include those shown in the accompanying figure:

    Click to enlarge.

    The webinar is targeted upon the needs of systems engineers, system integrators, communication engineers, information system security engineers, validation engineers, test engineers, defense engineers, contractors and consultants, application engineers, systems and requirements analysts and system administrators who wish to firm up their understanding of resilient PNT and expand upon the alternatives available to them. Speakers on the webinar will cover the topic from a range of perspectives.

    Mike Jones has worked on a variety of UK and US military airborne platforms around the world. He specializes in the simulation, modeling and hardware implementation of advanced signal processing algorithms, and has led a number of FPGA and ASIC designs for radar, GPS and communications systems.

    Mikel Miller began his career as a satellite systems engineer with the U.S. Air Force, holding numerous test, research and development, and program management positions. He retired with a Ph.D. and rank of lieutenant colonel. He worked until recently as chief scientist for PNT Technologies for the Air Force Research Lab Sensors Directorate, and is now a vice president at Integrated Solutions for Systems (IS4S).

    Miller will broaden the discussion to encompass all three technologies that evolved military applications and platforms now require for synchronized, precision operations: resilient PNT, resilient communications, and resilient cyber. A system-of-systems architecture that integrates and optimizes these three technologies is required to provide trusted and resilient PNT information in GNSS denied/degraded environments.

    Randy Villahermosa, executive director, iLAB, The Aerospace Corporation, will speak on research concepts in complementary PNT, including open-source frameworks and the potential role of signals-of-opportunity navigation. The iLab is a venue for “exploring, prototyping, and collaborating.”

    Lisa Perdue, an expert in testing critical GPS and GNSS systems,  has trained hundreds of engineers and technicians who are responsible for high-reliability positioning, navigation and timing (PNT) applications. Perdue is Spectracom product manager at Orolia, where she directs the organization’s GNSS simulation activities and contributes to its entire portfolio of resilient PNT solutions. She has more than 15 years of navigation and RF systems experience, including 10 years of service with the U.S. Navy, where she was a certified master training specialist.

    Spectracom’s perspective on secure military systems is concisely set out in a whitepaper, “Making Military PNT Systems Resilient Against Threats: Recent Advances.”  After an overview of the field in which many terms and concepts are carefully and helpfully defined, the whitepaper explains the advantages of the new Satellite Time and Location (STL) service. This is a paid option available on the company’s VersaPNT hardware unit, combining a GNSS receiver, inertial measurement technology and high-performance timing oscillators to provide assured PNT in GNSS-degraded and denied environments.

    STL is a new technology available today to harden GNSS-based timing and frequency systems, and in some cases even to replace the GNSS reference; the adaptation of this technology to positioning and navigation applications on slow-moving mobile platforms is currently under development. The STL signal is broadcast by the Iridium constellation of satellites in low-Earth orbit.

    VersaPNT reduces size, weight and power (SWaP) by combining the the PNT functions of multiple independent subsystems  in one portable unit with a modular architecture. For improved resiliency, optional interference detection and mitigation (IDM) software can be added, as well as other services such as STL and BroadShield.

  • Resilient PNT for defense highlighted in Nov. 16 webinar

    As a U.S. military system, GPS provides all the PNT capabilities they need for defense — until it doesn’t.

    Though the accuracies are great and the encrypted signal is resistant to spoofing, its weak signal is very susceptible to jamming. GPS World will host a webinar Nov. 16 to examine ways to augment GPS/GNSS to add resiliency so critical military systems have assured PNT. Registration is free.

    Speaker Mikel Miller — Air Force officer (ret.), chief scientist for PNT and instructor — said, “As military operations have evolved over time, three critical technologies have become foundational in synchronized, precision military operations: resilient PNT, resilient communications and resilient cyber. A system-of-systems architecture that integrates and optimizes these three technologies is required to provide trusted and resilient PNT information in GNSS denied/degraded environments.”

    Sponsored by precision time company Spectracom, the webinar takes place Nov. 16 at 1 p.m. EST / 10 a.m. PST / 7 p.m. (1900h) Central European Time.
