  • Out in Front: Tell the Truth, Now

    Here are a few things about your colleagues that perhaps you did not know: they are a quite colorful, varied, and shall we even say motley crew. Hidden backgrounds came to light during the magazine’s Leadership event in Nashville, during a game called “Guess Who’s Spoofing the Dinner?” One person at each table, secretly recruited in advance, lied freely in response to three questions, while everyone else was bound to tell the strict truth. The table then had to identify the spoofer in their midst.

    The truths turned out to be stranger than the fictions. As ever. This is what’s known, appropriately, as a truism.

    The questions posed:

    • What is the farthest from your birthplace that you have traveled?
    • What was the shortest time you ever held a job? What job?
    • Who is the most famous person you have met?

    One person had met Hillary Clinton, another the first lady of China, and two people had met the Queen.

    One met Janis Joplin (throwing that table into a total tizzy), another had an audience with two popes, Benedict and John Paul II (not simultaneously), while yet another had met John Paul II and Sophia Loren (again, presumably, not on the same occasion).

    But the most elevated encounter was described by a soft-spoken gentleman who taught the Dalai Lama to play frisbee. His Holiness had never done, and evinced some curiosity as to how it worked.

    Janis Joplin’s crony claimed his shortest employment was installing fire alarms at a Catholic home for girls in a delicate way in the early Sixties. His table declared him the spoofer. But they were wrong. They were wrong.

    The shortest employment for one engineer at the dinner was also his longest, not to mention his most current: 30 years. He has never held another job.

    One young researcher worked briefly as a shepherdess, until getting trampled by a flock of sheep. Imagine your lab-coated colleague in a long white frock, ruffled cap, and crook stick.

    In their travels, folks had reached Tierra del Fuego, Tasmania, Everest Base Camp, China (and conversely, Nashville from China by a select few), and Capetown, South Africa, but the furthest flung had landed on Antarctic ice in a Hercules C-130, on skis.

    Ironically, one travel tale was challenged not because of the furthest destination but the start point. A well known GNSS scientist vowed that he came from Texas, but a gentleman from the European Commission — the same who had met John Paul and Ms. Loren — doubted this severely, because the teller did not sport cowboy boots nor a big belt buckle. Worse, he could not recall what Sam Houston’s boys cried out as they went into the Battle of San Jacinto, winning glory and Texas independence.

    Italians, it seems, are quite well versed in Texan history.

    There is a lesson in this for all of us, though our scientist claims it’s all just an invention of  the movies.

    Remember the Alamo!

    Out in Front: Virtuosos

    Cover: Curiosity By Philip Ball
    Cover: Curiosity By Philip Ball

    An occasional reader of these pages forwarded a clipping from a summer Wall Street Journal, a book review of the new title, Curiosity: How Science Became Interested in Everything, by Philip Ball (University of Chicago Press, 465 pages, $35).

    The book covers scientific advances logged in the 1600s, a century that “began with an essentially medieval outlook and ended looking like the first draft of the modern age.” However, the book’s description by WSJ reviewer Timothy Ferris quickly called to my mind the current status of investigation — practiced with an overlay of capitalism and market advantage-seeking — by, guess who, the GNSS community.

    Not that I’m necessarily equating the scientists, engineers, and product managers who are responsible for most of the contents of this magazine with the “thousands of independent tinkerers, inventors, collectors and flat-out oddballs, the ‘virtuosos’ as they were called, [who] experimented with lenses, pumps, and biological specimens as much to satisfy their own inquisitiveness as to answer big questions.”

    Far from it. Perish the thought.

    And yet, and yet . . . .

    I sat in a Denver airport cafe on my way home from ION GNSS+, chatting with a couple of industry captains about the way forward. We joked about how our kids will look at us as old fogeys — heck, they already do — tentatively feeling our way to indoor navigation. This method, that method? This augmentation, that integration?

    The rising generations will simply take it for granted: indoor nav works everywhere, all the time, in the palm of your hand, or perhaps in the frame of your eyewear. How quaint were those early 21st-century inventors! Tinkering with different RF bands, trying to cobble together a solution.

    The smiles on the faces of these industry captains as they proudly showed each other their devices, running their latest prototypes, and curiously examined their competitors’ versions, betrayed an enthusiasm, not just for market share, but for intellectual stimulation, the thrill of the chase, the joy of solving a problem. In that way, they were not unlike the 16th century crew, an assemblage that included, among many minor and forgotten names, Galileo (!!!), Kepler, Newton, Descartes, and Leibniz.

    “The truth is that science works,” writes Philip Ball, “only because it can break its own rules, make mistakes, follow blind alleys, attempt too much — and because it draws upon the resources of the human mind, with its passions and foibles as well as its reason and invention.”

  • Out in Front: Geospatial on Everything

    GPS World Publisher Learns about GIS

    By Alan Cameron

    Everything has a geospatial aspect. Everything. Past, present, future.

    Over grits, coffee, and the airborne delicacy purveyed at the Flying Biscuit Cafe (right out of the oven, right into your mouth) in Sandy Springs, Georgia, I absorbed this high-tech homily.

    You’ve heard of the European financial crisis. Trace it back to geospatial, from the Greek banking collapse, which in turn had roots in the implosion of the Greek tax system, due to a plethora of gaps, inconsistencies, and exceptions filed in a largely uncontrolled property cadastre — the register of real property, including details of ownership, precise location (by GPS coordinates), and value of land parcels.

    Lose control of your cadastre (your GIS), lose the country. With global interconnections, soon the continent, if not perhaps the world economy.

    For want of a nail, the battle was lost.

    Jump forward, technologically, to flash lidar. Ball Aerospace created this ability to capture continuous rapid multiple laser interferometry detection and ranging (LiDAR) images/point clouds, merged with continuous high-resolution optical images, to create full-color 3D models in real time. Stitched together with GPS, this produces real-time full-motion video: interactive geo-referenced metric 3D models.

    In field application, this can yield time-critical 3D mapping for urgent missions, enhanced situational awareness, battlefield characterization, and tactical mission planning. It can help with disaster-response planning and event forensics. Real-time models could be communicated with the public through easily comprehended moving images via television or the Internet. of the actual progress of a fire or flood, together with evacuation routes.

    Jump again to fabfi. What’s a fabfi?

    FabFi is an open-source, lab-grown system out of MIT using common building materials and off-the-shelf electronics to transmit wireless Ethernet signals across distances up to several miles. Communities can build their own networks for high-speed Internet connectivity, and access to online educational, medical, and other resources.

    Simple, low-cost, and feasible in unstable environments: Afghanistan, Kenya, and any number of countries that leapfrogged telephone landlines to come quickly into the cellular era; now they can leapfrog Ethernet cable networks and even Wi-Fi for virtual connectivity. Implement with locally available materials. Print out a 2D design file and create the pieces out of wood, metal, acrylic, clay, stone, or ice, as long as you can attach a metallic RF reflective surface to the front.

    If you haven’t guessed the geospatial aspect of this, I assure you it’s there, but I’ve run out of room here.

    For these geospatial glimpses, I am indebted to contributing editor Art Kalinski. Read his monthly columns here.


    Alan Cameron is editor-in-chief and publisher of GPS World magazine, where he has worked since 2000. He also writes the monthly GNSS System Design e-mail newsletter and the Wide Awake blog.

  • Out in Front: A Star Is Born

    Welcome to the club, India, and happy Birth Day. With the July 1 launch of IRNSS-1A, India and the Indian Regional Navigation Satellite System have officially joined the GNSSS (Global Navigation Satellite Systems Society).

    With full membership, however, come some society duties and responsibilities. Chief and first among these is to provide all other society members and interested parties with an interface control document (ICD) defining the characteristics of the signal transmitted from one’s satellites to navigation receivers on the specified radio frequency(ies).

    IRNSS signal transmitters will operate in L5 band (1176.45 MHz) and S band (2492.028 MHz). The system targets provision of an absolute position accuracy of better than 10 meters throughout the Indian landmass and better than 20 meters in the Indian Ocean, as well as a region extending approximately 1,500 kilometers around India.

    Who needs an ICD now, you ask? Who wants to navigate the Straits of Hormuz or New Delhi’s traffic jams using one satellite? No one, of course.

    But nearly every GNSS product developer, designer, and manufacturer has a vested interest in quickly getting their hands on such a document, if they want to sell goods in India, a market of very significant size. Development, design, and manufacture cycles are long, especially when you begin with new and unknown quantities such as a new signal in space. IRNSS once posted a very aggressive schedule: beginning in 2011, it planned to launch two satellites per year, to achieve a full constellation of seven by the end of 2014. Of course, it has fallen a bit behind that curve with first launch in 2013. This would push its operational date to end of 2016. Not all that far out.

    As our OEM editor Tony Murfin wrote last year in a BeiDou context, developers are building digital signal processing application-specific integrated circuits with so-called generic reconfigurable channels to accommodate future add-ons — but RF front-end hardware and signal processing software still require lengthy research and development. Generic DSP channels and associated software decoding algorithms may not be generic enough for all the things that  might await in new modulation schemes yet to come online.

    So it’s not just rabid intellectuals like the Noble New Brunswegian, my friend, colleague, and GNSS mentor and our intrepid Innovation columnist, who prodded me up on this bully pulpit  to ask: O India, where is thy ICD?

    The world’s breadth and depth of GNSS wants to know.

  • Out in Front: Uh-oh for Information

    Back around 1992, in the early days of the World Wide Web, a starry-eyed pundit trumpeted “The Internet will do for information what TV did for entertainment!”

    “Uh-oh for information,” riposted an editorial cartoonist at the time.

    To be sure, television since the 1950s has brought a few new high points of entertainment into homes around the world, as well as faster and farther-reaching news coverage. It has also brought widespread new lows, entire days’ and evenings’ worth of dumb-down, and news that is broad but shallow. In the process television birthed the terms “a vast wasteland” and “sound bite.”

    The Internet followed a similar path. As a consequence, more information is far more widely available. But is it any better, more reliable, more accurate, or conducive to better decisions? A strong argument can be made for the position that it is not; that, on the contrary, it is actually worse, or at the very least, less robust.
    At the same time that the Web began climbing into society’s lap, nevermore to budge, the cellular telephone attached

    itself to the human ear, not merely in the accustomed indoor stationary position but on the street, in the supermarket aisle, at the restaurant, behind the wheel. Now the smartphone has taken over that role and staked its ownership to the field of view as well, if not to total sensory consciousness.

    And what do you know? Along came GPS in the technological bargain. All apps, if not all things, become possible when you combine: Internet, mobile phone, and satellite-based positioning.

    From the interbreeding of these three springs the latest guest to the party: Big Data.

    What the heck is big data?

    “Data sets . . .  gathered by ubiquitous information-sensing mobile devices, aerial sensory technologies (remote sensing), software logs, cameras, microphones, radio-frequency identification readers, and wireless sensor networks. The world’s technological per-capita capacity to store information has roughly doubled every 40 months since the 1980s; as of 2012, every day 2.5 quintillion (2.5×1018) bytes of data were created.”

    I had to check Wikipedia (I know, I know, the prophet hoisted by his own petard) because I had only a vague sense of it myself.

    According to Adam Jacobs, writing in the ACMQueue of the Association for Computing Machinery, big data is so hefty that “[its] analysis requires massively parallel software running on tens, hundreds, or even thousands of servers.”

    Sounds like a job for Biggest Brother.

    Indeed, the government has stepped forward to shoulder the burden; we have only just learned that it did so some time ago. Now not only our phone calls but our locations, our travels, our appointments, can be well known to anyone behind the giant curtain who has a curiosity. If they feel bothered enough to get a warrant, warrants can be got. Cases on record show that the government has opened personal cell-phone records both with and without warrants.

    To rehearse the evident, those records now contain our location data. Breadcrumbs. The granularity, the precision, and the hertz-rate of that location data will only increase over time.

    This time around, the “uh oh” comes from the information.

    Uh oh for us.

  • Out in Front: Ruminations Upon a Technical Program

    The Institute of Navigation’s (ION’s) advance program for the 2013 GNSS+ conference in September arrived in the mail the other day, and was avidly consumed. The technical sessions of this gathering are prime hunting ground for presentations that later become articles in this magazine, as are, to lesser extent, those of the European Navigation Conference, the Joint Navigation Conference, CTIA, ITS World Congress, and others.

    Something struck me as I scanned the 280-odd presentations listed under 36 session tracks: the frequency with which the word BeiDou appeared. To determine if there were any substance to this fleeting impression, I essayed a quantitative analysis. Naturally, GPS and the generic GNSS occurred times beyond measure, but this is how the others fared.

    IRNSS: 1
    QZSS: 3
    GLONASS: 10
    Galileo: 13
    BeiDou: 19.

    What does this signify? Little enough, possibly. Still, something. A satellite navigation system bursts seemingly out of nowhere and within a few short years virtually laps the field, putting 20 (14 usable) transmitters into space and establishing a regional operating capability, soon to be global. That sort of thing tends to get noticed.

    The titles of BeiDou-focused papers on tap this fall in Nashville — not all of them springing from the laptops of Chinese engineers, not by a long shot — add substance to this passing fancy.
    ◾    BeiDou Consumer Receiver Chips at Last.
    ◾    A Combined GPS/BeiDou Vector Tracking Algorithm for Ultra-tightly Coupled Navigation Systems.
    ◾    Towards the Inclusion of Galileo and BeiDou/Compass Satellites in Trimble CenterPoint RTX.
    ◾    New Assisted BeiDou Products from JPL’s Global Differential GPS System.
    ◾    BeiDou Integration in Cell Phones and Tablets.
    ◾    BeiDou — A System That is Now Ready for Applications.
    ◾    Augmenting GPS RTK with Regional BeiDou in North America.
    ◾    New Systems, New Signals, New Positions — Providing BeiDou Integration.

    The affiliations of some of the authors of the above read like a top-level directory of North American and European GNSS manufacturers. Clearly, the ground has been plowed and the fields lie ready — if they are not already planted. Unless that’s too mixed a metaphor for satellite radionavigation signals.

    The recent acquisition of one Western GNSS manufacturer by a major Chinese business concern has not gone unnoticed, either.
    For more intelligence, I consulted the newest member of this magazine’s Editorial Advisory Board. He replied to my emailed penny for his thoughts.

    “I would be happy to contribute a column for the July issue based on my observations here at the China Satellite Navigation Conference in Wuhan. The article would be titled: Little Tigers versus Wolves.”

    Wow. Now I wonder, who’s who?

  • Out in Front: The System, Simulated

    Wealth, breadth, and depth. That’s what this issue brings you, in signal simulation- and testing-related content. Unfortunately, the wealth on offer has to large extent elbowed out our two news sections, The Business and The System. The former is given short shrift in this issue and the latter even shorter herewith, in pithy precis with website shortcuts. And our apologies.

    Let’s all remember, brevity is the soul of wit.

    GPS III Flexible Signal Generator. With completion of the Delta Preliminary Design Review for the GPS III satellites, Lockheed Martin and the U.S. Air Force announced that “an innovative new waveform generator permits the addition of new navigation signals after launch to upgrade the constellation without the need to launch new satellites.”

    IGS Real-Time Service. The International GNSS Service, a worldwide federation of agencies involved in high-­precision GNSS applications, announced the launch of its Real-­Time Service (RTS). The RTS is a global-scale GNSS orbit and clock correction service that enables real-time precise point positioning and related applications requiring access to IGS low-latency products. The RTS is offered in beta as a GPS-­only service for the development and testing of applications.

    QZSS Will Grow to Four. The Japanese government has ordered three navigation satellites from Mitsubishi Electric Corp. to expand the Quasi-Zenith Satellite System, currently orbiting the sole Michibiki. QZSS augments GPS navigation signals for users in the Asia-Pacific region. NEC Corporation has been awarded a contract for the QZSS ground control segment.

    Real-Time PPP with Galileo. Fugro Seastar AS achieved this task within a week of all four Galileo satellites being activated. Fugro is now generating Galileo orbit and clock corrections, which can be used in conjunction with the Fugro G2 decimeter-level corrections associated with its GPS/GLONASS PPP service.

    BeiDou Ground System Approved. The BeiDou Ground-Based Enhancement System (BGBES), a network of 30 ground stations, an operating system, and a precision positioning system, was approved by a Chinese government evaluation committee. The system is expected to improve BDS positioning accuracy to 2 centimeters horizontal and 5 centimeters vertical via tri-band real-time precision positioning technology, and to 1.5 meters with single-frequency differential navigation technology.

    CNAV Test on GPS L2C and L5. The U.S. Air Force Space Command announced that CNAV capabilities on the GPS L2C and L5 signals will be tested in June. The civilian navigation message to be carried by modernized GPS will have similar data to the existing NAV message, but its structure will be different, with increased message bandwidth for greater information density. L2C and L5 users and receiver manufacturers are encouraged to review the test plan, provide comments, and participate in the evaluation process.

    GPS at the Smithsonian. Brad Parkinson’s presentation, “GPS for Humanity — The Stealth Utility,” is now available as video on UStream.The talk helped introduce the new Smithsonian National Air and Space Museum exhibit, “Time and Navigation: The Untold Story of Getting from Here to There,” which is now open and free to the public in Washington, D.C.

    Out in Front: Galileo’s World

    GWpigeonIt’s been a long time coming. With the capability to make a position fix from four signal-broadcasting satellites, we can now say that Galileo has truly arrived. Of course, this is only one of many milestones (excuse me, kilometer markers) along the way, a trajectory that could be bounded at 23 years and counting, or possibly longer. Let’s not forget, GPS had an extended gestation period of its own, as did GLONASS; BeiDou appears to be maturing a bit faster.

    My acquaintance with the system began in July 2000, when I joined the staff of GPS World and received my first assignment, editing an article about GPS-bearing carrier pigeons in the sister publication Galileo’s World, from founding editor Glen Gibbons. We published Galileo’s World quarterly from 2000 to 2002, chronicling the ups and downs, forward steps and back, of the European GNSS. GWgreeceUnless you counted EGNOS — really telecom satellites with a piggyback SBAS payload — Galileo had no space vehicles as yet, but did encompass plenty of political and financial maneuvering, rhetoric, market projections, international negotiations, and technical blueprints. In short, the stuff of news. For application stories in the magazine, we filled with European uses of GPS, all of which would eventually integrate Galileo as well.

    In 2002, a UK-based travel agency of the same name began to assert its legal possession of the name Galileo, and sent a cease-and-desist shot across the bows to the corporate ownership of the two magazines, and to the European Union. The EU felt it had sufficient legal clout or standing of some kind, for it neither desisted nor renamed its space program. But our counsel at the time instructed us to quietly fold up our tent and steal away. The impending battle wasn’t worth our stake.
    GWferry

    And so Galileo’s World sadly ceased publication. Not for lack of interest, or support, or commitment. But because of someone else’s greed or turf belligerence in a completely unrelated market. Such is the way of the global economy.

    We have covered every step of Galileo’s way, technically, economically, and politically, in the pages of GPS World. Occasionally we ponder calling ourselves GNSS World, or even PNT World. But the brand, like the satnav system it is named after, is just so strong, it would be foolhardy to walk away from it, at this point in time at least.

    GPSgalsisWe continue to support European satnav progress at each successive stage. And so we say yet again: Welcome, Galileo!

  • Out in Front: The Semi-Private Life of Waldorf Twitty

    We’re going through!” The Captain’s voice was like thin slate breaking. He wore combat fatigues with a dusty beret.

    “We can’t make it, sir. They’re laying down fire too heavy, if you ask me.”

    “I’m not asking you, lieutenant,” said the Captain. “Go to overdrive!”

    The throb of the diesel Stryker increased: cha-rugga-rugga-rugga. He surveyed the rocky defile ahead. “Throw back the shield!” he shouted. “Swing out the M240!”

    The crew, bending to tasks in the rocking transport, grinned. “The Old Man’ll bring us through,” they said. “The Old Man ain’t afraid of hell!” . . .

    “Get a free muffin with your next mocha latte!” Waldorf Twitty’s phone on the passenger seat squawked.

    “Hmm?” said Twitty. He regarded the smartphone in mild astonishment. “You’re within 15 meters of Studbricks. Bring your e-coupon now!” Waldorf Twitty drove on in silence, the fire of the worst ambush in years of guerilla warfare fading in the airways of his mind. “Recalculating!” yapped the phone urgently. “Head for Studbricks!”

    Waldorf Twitty proceeded to a parking lot at town’s edge. He hefted his laptop, pocketed his phone, and crossed the green expanse of industrial campus toward a distant office block, passing a clinic that ministered to employees.

    . . . “It’s the billionaire investor, Boren Wellfleet,” said the pretty nurse.

    Waldorf Twitty put down his external hard drive, repository of his own medical research. “Who has the case?”

    “Dr. Debakow, and a specialist, Dr. Farnyard, has flown in.”

    A door opened and Farnyard emerged, distraught. “It looks bad for Wellfleet. Obstreosis of the ductal tract. Tertiary. Wish you’d take a look.”

    “Glad to,” said Twitty.

    In the operating room Dr. Debakow whispered, “I’ve read your blog on streptothricosis — brilliant.” At this moment a machine with many displays began to go rugga-rugga-rugga.

    “The new anaesthetizer is giving way!” cried an intern. “No one knows how to fix it!”

    Twitty glided to the machine, now going rugga-rugga-queep-rugga-rugga-queep. “Give me a USB drive!” he snapped. He inserted the device in his own hard drive, then into a port on the trembling, moaning anaesthetizer. “That will hold for ten minutes,” he said. “Get on with the operation.”

    “Coreopsis has set in,” said Farnyard nervously. “Would you take over, Twitty?”

    “If you wish.” . . .

    “I see you! You’re in the geofence!” his boss’s voice barked. Waldorf Twitty halted and looked around; people passed tranquilly to and fro. “I’m tracking your phone now — why aren’t you here yet? Where’s the Veeblefreetzer design!?! Why weren’t you in at 6 this morning?”

    Twitty groaned. He had never figured out how to disable the location transmit function on his phone. Every app he downloaded — and he had many — claimed location-sharing could be turned off, but they buried the settings so deep. He turned back to the parking lot. He would call in sick. Or something.

    . . .The dark-haired beauty took his hand. “You’ll lead us out of here?” she quavered. He nodded grimly. . .

    “Say, bud, looks like you’re under-insured!” a friendly voice boomed from his pocket. “Bill Lacky with Consolidated Coverage, friend of your friend’s friend on Facebook, and a 3rd removed on LinkedIn. I’m just a few blocks away. I bet I can get an introduction from someone by the time I’m there. Heading your way!”

    At a corner he leaned against a wall in the shade. “This is the police, Mr. Twitty. We are authorized to make an employer’s arrest. Hold your phone and stand perfectly still. An officer has your coordinates and will arrive shortly.”

    . . . He put his shoulders back and his heels together. “To hell with the blindfold,” said Waldorf Twitty. Then, with that faint, fleeting smile on his lips, he faced the firing squad: erect, motionless, proud and disdainful. Waldorf Twitty, inscrutable to the last.

  • Out in Front: Stand By to Capsize

    We have reached our tipping point, say the seven U.S. military Joint Chiefs of Staff in a January 14 letter to Senator Carl Levin, chairman of the U.S. Senate Committee on Armed Services.

    “We are on the brink of creating a hollow force,” they continue. By this they mean that the military of the size that they are required to maintain may be incapable of performing the duties for which it is relied upon.

    This sounds a great deal like the scenario forecast in Don Jewell’s “2C or Not 2C” column in this magazine. Five GPS satellites currently on orbit have the capability of broadcasting new signals essential to security and economic growth. But that capability is hollow because of a lack of — what? money? resolve? back-up? — to turn it on and use it. Those satellites could actually die in a couple of decades without ever performing the function for which they were designed.

    The hollow-force concept as applied to the GPS constellation reverberates eerily through John Lavrakas’ “BeiDou, How Things Have Changed” piece in this issue. If GNSS matters continue developing along the same paths they follow now, the hierarchy of satnav systems, by user numbers, market share, health, robustness, economic viability, yea even unto military prowess, may well shift.

    The uncertain fiscal year 2013 funding caused by the combined effects of a possible year-long Continuing Resolution in the U.S. Congress and radical budget surgery known as sequestration currently has military chiefs directing severe reductions to operation and maintenance spending.
    Operations and maintenance keep satellites flying.

    “Our proposed near-term actions,” write the civilian Secretary of the Air Force and the U.S.A.F. General Chief of Staff, “include . . . defer[ring] non-emergency Facilities Sustainment, Restoration, and Modernization  (FSRM) projects, resulting in a reduction of roughly 50 percent in FSRM spending; where practical, de-obligat[ing]/incrementally fund[ing] contracts to encompass only FY13.”

    Modernization will (or would) keep GPS apace with user requirements, growing security needs, and an increasingly digital world. Incremental funding has delayed new signals and new capabilities time and again; sounds like it’s set to do more.

    “For now, and to the extent possible, any actions taken must be reversible at a later date in the event that Congress acts to remove the risks I have described,” writes Ashton Carter, Deputy Secretary of Defense, to nearly every one under the sun connected with the military and money.

    When is decay reversible? The notion of a tipping point is that, once passed, it cannot be re-crossed again in the opposite direction. Neither the status quo nor stability can be restored.

    Many of us in the private sector have gone through successive rounds of cutbacks and lay-offs. Such measures first trim away the fat. This can be healthy, to some extent, although fat stores energy for later use. Then they start slicing into muscle. This reduces the ability to function. Finally, in many cases, they take a hacksaw to the bones. This not only cripples the organism, it effectively destroys it.

  • Out in Front: Let the Chips Fall

    We either continue to totter at the brink of a global financial precipice, or we sit crumpled on the canyon floor far below, peering skyward, wondering what might have been, and resolving to pick up what pieces we can and carry on.

    It is impossible to tell as this magazine goes to press in December just where we may find ourselves, and in what shape, come the early days of January 2013. Those elected parties with responsibility for the state of our fiscal affairs, who in the best of all possible worlds would  possess some sort of vision for the future, continue to posture, prevaricate, pander, and generally excuse themselves from worrying about what may happen to the rest of us. After all, they will still be in office and drawing good salaries come the New Year, come what may.

    The GNSS industry has pulled through the last half-decade of worldwide recession as well as most, better than many. There have been some casualties along the way, and almost universal belt-tightening. But we keep moving onward and upward, blessed with a technology that continues to find new and profit-bearing applications, and encouraged by researchers further out in front of us, who discover and develop yet newer possibilities at an astonishing rate.

    Now we face new uncertainty. The domino-paths of the global economy wend this way and that, curving, intertwining, doubling back, snaking everywhere. A toppled piece here can lead to a cascaded pile-up way over on the other side of the board, and vice versa.

    It all comes down to end-user ability to buy, to upgrade, to invest in the future — as opposed to holding tight to whatever can be preserved in the present.
    If characterizing GNSS end-users could be done by naming off surveyors, farmers, fishermen, and other outdoor enthusiasts, then determining the economic outlook for this industry would be easier to do, though the picture might not necessarily be any more optimistic. But the GNSS end-user community has swelled almost immeasurably to include the automotive industry, the telecommunications industry (in both its infrastructure and its own end-user equipment), utilities, airlines and the aircraft industry, militaries around the world, and even governments themselves — municipal, state, and national. Every one of these entities has a budget and acutely feels the chills — and in more delayed fashion, the warnings — of national and global economies.

    Should the United States Congress, in full possession of all its political wisdom, drive the country over the fiscal precipice, reverberations of the crash in the chasm below will propagate far and wide — and into the very marrow of our bones.

    We have overcome before. With science and technology as our co-pilots (or are they our engines?), we shall overcome again. We may and should speak out, attempting to influence the political process, but we cannot control its outcomes.

  • Letter to the Editor: Our First Mistake

    Our first mistake is to presume an environment of perfection and security. Nothing is foolproof and spoof-free. Every product or service is an envelope of packaging that can be opened, peeled back, reversed engineered, and replicated. I have seen “ultimate security” defeated repeatedly.

    GPS is no exception, of course. We put our signatures and seals on these things; enterprising competitors, adversaries, and curious people find a way to steam open our envelopes, create seals indistinguishable from the original, or simply use products in ways unexpected.

    We exist in a world headed pell-mell toward the product consumerization, as GPS World tells us, as if this is new. We BYOD [bring your own device, a business policy of employees bringing personally owned mobile devices to their place of work and using those devices to access privileged company resources such as email, file servers, and databases, as well as their personal applications and data.  — Ed.] to work with its purchase by credit card and reimbursement by petty cash. This is nothing new than a newer terminology for mass-merchandizing.

    Wars will be fought that way too, as if they always weren’t. Soldiers built their own grenades, brought their own weapons, horses, uniforms, and food to the contested game … always. Patton had his own pair of pearl-handled Colt sidearms.

    The pressure for encrypted GPS and inconvenient milspec devices misses this reality. Our every weapon will fail unintentionally, get repurposed by knowledgeable adversaries, and be turned intentionally against us. We cannot engineer away these consequences. We can only be better readers. We must be flexible competitors. We have to be open to the reality that everything fails in ways we will not anticipate but should expect.

    War is not fought in rows with toy soldiers equal and alike arrayed with fair rules. Fourth generation warfare is here. War is an expediency when diplomacy, economics, and reason fail with adversaries and friends alike. It is fought with a dangerous expediency.
