Why Is the U.S. Government Working Frantically to Get Rid of GPS?

A new project out of Northrop Grumman and DARPA has the potential to make GPS obsolete.

Technically speaking, the Pentagon's top-secret weapons lab, "DARPA," stands for the Defense Advanced Research Projects Agency. You could just call it the Defense Department's office of "Wow!"

Since its inception in 1958, DARPA has played a role in the creation of such technological wonders as the Internet (once known as ARPAnet), humanoid and animal-form robots, unmanned aerial vehicles of all shapes and sizes, and even Global Positioning Satellites, or GPS. DARPA's latest project -- "C-SCAN" -- has the potential to improve and perhaps even replace GPS.

10 times more interesting than C-SPAN
Teaming up with Northrop Grumman (NYSE:NOC) as its primary contractor, DARPA is working today to integrate micro-electro-mechanical systems, called MEMS, and atomic inertial guidance technologies, forming a new "single inertial measurement unit" in a project designated the "Chip-Scale Combinatorial Atomic Navigator" -- C-SCAN.

Translated into plain English, what C-SCAN aims to accomplish is to create a chip that performs the functions today served by orbiting GPS satellites. The chip would constantly "know" where it is in space-time, and would have this knowledge without having to ping a satellite (and maintain line-of-sight communication with a satellite) to do it.

Why do it?
If you've ever tried to access the GPS system on your car while parked in a garage, and been unable to do so while the device is "searching for satellites," you'll understand the usefulness of a device that can perform like GPS, without need for actual GPS. Elimination of the need to rely on satellites to determine one's location would similarly enable the use of "GPS-like" technology for getting directions within buildings and underground -- for example, in subway systems.

So C-SCAN has obvious civilian applications. Of course, DARPA's primary aim is enhancing the functioning of the nation's military. And C-SCAN would be invaluable for that purpose.

Why we need to do it
One of the primary vulnerabilities in today's hi-tech, ultra-accurate weapons systems, you see, is their dependence upon GPS signals to guide them to their destinations. American "smart bombs" and guided missiles all depend greatly on GPS to know where they are, and to get where they're going. American dominance in drone technology, similarly, depends on GPS.

Problem is, while we know this is a problem, the "bad guys" know it, too -- and can sometimes hack GPS signals so as to confuse, and even hijack, American weapons systems. Case in point: in 2011, Iran boasted that it had commandeered and captured a Lockheed Martin (NYSE:LMT) RQ-170 Sentinel -- one of our most advanced "stealth" surveillance drones -- in flight over Iranian territory. The Iranians didn't have to shoot the drone down, either. Instead, they forced it to land in Iran, and captured it intact. According to Iranian engineers, this was accomplished by first jamming communications with the Sentinel's remote controllers, then "spoofing" GPS signals, tricking the drone into landing at what it thought was its home base in Afghanistan -- but what was actually an Iranian airfield.

Drones equipped with a future C-SCAN technology would be less likely to fall victim to such a trap. While their communications might be cut off, forcing them to default to autopilot and return to base, they'd at least return to the right base, because an internal chip would tell them how to get there.

The future is now
Current weapons systems often include internal gyroscopes, granted, that perform some of the functions that C-SCAN aims to perfect. But as DARPA observes, present-day gyroscopes are "bulky" equipment, "expensive," and don't perform with the kind of accuracy that DARPA wants to see.

The objective, therefore, is to explore cutting edge technologies to put gyroscope-like functionality on a chip, resulting in "small size, low power consumption, high resolution of motion detection and a fast start up time" -- all loaded onto one small microchip.

What it means to investors
If DARPA succeeds with C-SCAN, it will have obvious benefits for the nation's bombs, missiles, and drones -- but it would also benefit Northrop Grumman as DARPA's primary collaborator on the project. Last quarter, Northrop saw its revenues decline 4% as the U.S. government increasingly tightened its belt on defense spending. Market researcher IBISWorld recently released a report projecting that total U.S. government spending on defense would shrink 2% annually, year after year, over the next five years. But by helping the U.S. government solve one of its most vexing defense problems, Northrop could help secure as big a piece as available, of the shrinking defense pie.

Indeed, it might help to grow that pie. Microchip-based guidance could be the solution the military is seeking to an oft-discussed problem with the nation's newest generation of Mach 7 railguns, whose great range, speed, power -- and cheapness -- make them an attractive weapons system... if we can only figure a way to guide their projectiles accurately.

Miniaturized, GPS-like guidance systems-without-satellites would be even more crucial for introducing this technology into civilian applications. While you could probably attach a gyroscope to your smartphone, you might have trouble getting it to fit in your pocket. But put the gyroscope on a chip?

Voila! Instant GPS functionality, indoors and out.

That's a future worth buying into, for defense investors, and tech investors alike.

Leaked: Apple's next smart device (warning, it may shock you)
When it comes to investing in hi-tech, Northrop's certainly one choice -- but Apple is usually the more obvious choice. Apple recently recruited a secret-development "dream team" to guarantee its newest smart device stayed hidden from the public for as long as possible. But the secret is out, and some early viewers are claiming its everyday impact could trump the iPod, iPhone, and the iPad. In fact, ABI Research predicts 485 million of this type of device will be sold per year. But one small company makes Apple's gadget possible. And its stock price has nearly unlimited room to run for early in-the-know investors. To be one of them, and see Apple's newest smart gizmo, just click here!

1 Key Step to Get Rich

Our mission at The Motley Fool is to help the world invest better. Whether that’s helping people overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we can help.

To be perfectly clear, this is not a get-rich action that my Foolish colleagues and I came up with. But we wouldn't argue with the approach.

A 2015 Business Insider article titled, "11 websites to bookmark if you want to get rich" rated The Motley Fool as the #1 place online to get smarter about investing.

"The Motley Fool aims to build a strong investment community, which it does by providing a variety of resources: the website, books, a newspaper column, a radio [show], and [newsletters]," wrote (the clearly insightful and talented) money reporter Kathleen Elkins. "This site has something for every type of investor, from basic lessons for beginners to investing commentary on mutual funds, stock sectors, and value for the more advanced."

Our mission at The Motley Fool is to help the world invest better, so it's nice to receive that kind of recognition. It lets us know we're doing our job.

Whether that's helping the entirely uninitiated overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we want to provide our readers with a boost to the next step on their journey to financial independence.

Articles and beyond

As Business Insider wrote, there are a number of resources available from the Fool for investors of all levels and styles.

In addition to the dozens of free articles we publish every day on our website, I want to highlight two must-see spots in your tour of fool.com.

For the beginning investor

Investing can seem like a Big Deal to those who have yet to buy their first stock. Many investment professionals try to infuse the conversation with jargon in order to deter individual investors from tackling it on their own (and to justify their often sky-high fees).

But the individual investor can beat the market. The real secret to investing is that it doesn't take tons of money, endless hours, or super-secret formulas that only experts possess.

That's why we created a best-selling guide that walks investors-to-be through everything they need to know to get started. And because we're so dedicated to our mission, we've made that available for free.

If you're just starting out (or want to help out someone who is), go to www.fool.com/beginners, drop in your email address, and you'll be able to instantly access the quick-read guide ... for free.

For the listener

Whether it's on the stationary exercise bike or during my daily commute, I spend a lot of time going nowhere. But I've found a way to make that time benefit me.

The Motley Fool offers five podcasts that I refer to as "binge-worthy financial information."

Motley Fool Money features a team of our analysts discussing the week's top business and investing stories, interviews, and an inside look at the stocks on our radar. It's also featured on several dozen radio stations across the country.

The hosts of Motley Fool Answers challenge the conventional wisdom on life's biggest financial issues to reveal what you really need to know to make smart money moves.

David Gardner, co-founder of The Motley Fool, is among the most respected and trusted sources on investing. And he's the host of Rule Breaker Investing, in which he shares his insights into today's most innovative and disruptive companies ... and how to profit from them.

Market Foolery is our daily look at stocks in the news, as well as the top business and investing stories.

And Industry Focus offers a deeper dive into a specific industry and the stories making headlines. Healthcare, technology, energy, consumer goods, and other industries take turns in the spotlight.

They're all informative, entertaining, and eminently listenable ... and I don't say that simply because the hosts all sit within a Nerf-gun shot of my desk. Rule Breaker Investing and Answers contain timeless advice, so you might want to go back to the beginning with those. The other three take their cues from the market, so you'll want to listen to the most recent first. All are available at www.fool.com/podcasts.

But wait, there's more

The book and the podcasts – both free ... both awesome – also come with an ongoing benefit. If you download the book, or if you enter your email address in the magical box at the podcasts page, you'll get ongoing market coverage sent straight to your inbox.

Investor Insights is valuable and enjoyable coverage of everything from macroeconomic events to investing strategies to our analyst's travels around the world to find the next big thing. Also free.
