U.S. Navy Brings Back Navigation By The Stars For Officers

"Raise your hand if you have ever determined your location on the planet using the stars," Lt. Daniel Stayton tells his class at the U.S. Naval Academy.

A young officer halfheartedly puts up her hand. Another wavers. The rest of the class of 20 midshipmen sits stone-faced.

This is the challenge facing the U.S. Navy as it tries to bring back celestial navigation. The Navy stopped training its service members to navigate by the stars about a decade ago, focusing instead on electronic navigational systems. But fears about the security of the Global Positioning System and a desire to return to the basics of naval training are pushing the fleet back toward this ancient method of finding a course across open water.

Navigation by the stars dates back millennia. The ancient Polynesians used stars and constellations to help guide their outrigger canoes across thousands of miles of the Pacific Ocean. And right up until the mid-20th century, navigation on the sea was usually done by looking at the heavens.

That changed in the late 1970s, when the military began launching GPS satellites. The satellite system provided a far more accurate fix than the stars could. In 2000, the U.S. Navy began phasing out sextants and charts in favor of computers.

Rear Adm. Michael White, who heads the Navy's training, says the change in curriculum was driven by the need to bring young officers up to speed on the Navy's equivalent of Googlemaps, called the Voyage Management System. It uses GPS, radar and other tools to precisely track a ship's position and course across the ocean. The system is complex and, "we don't have infinite training time available," White says.

So, why return now to the old ways? The Navy and other branches of the U.S. military are becoming increasingly concerned, in part, that they may be overly reliant on GPS. "We use it to synchronize all military operations, we use it to navigate everywhere — it's just something the U.S. military can't live without," says Brian Weeden, a former Air Force officer now with the Secure World Foundation, a nonprofit that studies security issues in outer space. In a big war, the GPS satellites could be shot down. Or, more likely, their signal could be jammed or hacked.

Already, jamming has become more common, Weeden says. "You can buy a lot of GPS jammers off the Internet," he says. "A lot of those are made by Russia."

He thinks the Russians probably have systems to jam the special signals the military uses as well. And China may be developing similar capabilities.

White, who heads the Navy's training, says there is also a desire to get back to basics. Over the past decade, electronic navigation systems on ships have become easier to use, so less training is required. He says the Navy is bringing back celestial navigation to make sure its officers understand the fundamentals.

"You know, I would equate it to blindly following the navigation system in your car: If you don't have an understanding of north/south/east/west, or perhaps where you're going, it takes you to places you didn't intend to go," he says.

In fact, there has been at least one incident in the past decade when a Navy ship ran aground partly because of problems with the electronic navigation system, investigators say.

Back in the classroom at the Naval Academy, the midshipmen finishing up their first course seem a little bewildered. Until now, says 20-year-old Audrey Channell, celestial navigation wasn't on her radar.

"I mean, obviously I heard about using stars to navigate in the old days," she says, "but I never thought I'd be using it."

Like many of the others in the class, she uses GPS to navigate her daily life.

Her instructor, Daniel Stayton, says that's OK. Nobody expects these young officers to become Magellans overnight.

STEVE INSKEEP, HOST:

You know, many of us rely on our smartphones to get from point A to point B. You know, you fire up your maps application.

AUTOMATED VOICE: Head west on Patterson Street northeast...

INSKEEP: You know, that's directions on Google Maps there that would get me home. The U.S. Navy does pretty much the same thing. GPS and digital charts have become the norm aboard many of its vessels, but the Navy is worried about electronic warfare. So as NPR's Geoff Brumfiel reports, it's returning to an ancient technique - navigating by the stars.

GEOFF BRUMFIEL, BYLINE: It's a Monday at the U.S. Naval Academy in Annapolis, Md., and the midshipmen are getting ready for their first lecture on celestial navigation.

DANIEL STAYTON: So raise your hand if you have ever determined your location on the planet using the stars.

BRUMFIEL: Lt. Daniel Stayton is leading the class. A midshipmen halfheartedly put ups her hand.

STAYTON: So at least one. All right, so I've got to stick to the truth then. I can't just make stuff up.

BRUMFIEL: Right up until the mid-20th century, navigation on the sea was done by looking at the heavens above. But starting in the late 1970s, the military began launching GPS satellites and everything changed. In 2000, the U.S. Navy began phasing out sextants and charts in favor of computers. Rear Adm. Michael White is in charge of the Navy's training.

MICHAEL WHITE: We do periodic reviews of our curriculum to make sure we're teaching the most appropriate material in the time allotted. We don't have infinite training time available.

BRUMFIEL: Training became focused on the Navy's equivalent of Google Maps, something called the Voyage Management System. It uses GPS, radar and other tools to precisely track a ship's position and course across the ocean. But after a decade of focusing on electronic training, the Navy is reversing course, and there are a couple of reasons why. First, the U.S. military is increasingly worried it's overly reliant on GPS.

BRIAN WEEDEN: We use it to synchronize all the military operations. We use it to navigate everywhere. It's - you know, it's just something that the U.S. military really can't live without.

BRUMFIEL: Brian Weeden is with the Secure World Foundation, a nonprofit that studies security issues in outer space, where GPS satellites orbit. In a big war, the satellites could be shot down or, more likely, the GPS signal could be jammed or hacked. Already, jamming is becoming more common, Weeden says.

WEEDEN: You can buy all kinds of GPS jammers off the Internet. Well, a lot of those are made by Russia.

BRUMFIEL: He thinks the Russians probably have systems to jam the special signals the military uses as well. And China may be developing similar capabilities. Adm. White, who heads the Navy's training, says there's also a desire to get back to basics. Over the past decade, navigation systems on ships have gotten easier to use, so less training is required. He says the Navy is bringing back celestial navigation to make sure its officers understand the fundamentals.

WHITE: You know, I would equate it to, like, blindly following the navigation system in your car. If you don't kind of have an understanding of north, south, you know, east, west or perhaps where you're going, it takes you to places you didn't intend to go.

BRUMFIEL: In fact, there's been at least one incident in the past decade where a Navy ship ran aground in part, investigators say, because of problems with the electronic navigation system. Back in the classroom, the midshipmen are finishing up their first course. And frankly, they seem a little bewildered. Twenty-year-old Audrey Channell says until now, celestial navigation wasn't on her radar.

AUDREY CHANNELL: I mean, obviously I've heard of, you know, in the old days using stars to navigate. But I never thought I'd actually be using it.

BRUMFIEL: Like many of the other midshipmen in this class, she uses GPS in her daily life. Her instructor says, that's OK. No one is expecting these future officers to become Magellans overnight. Geoff Brumfiel, NPR News. Transcript provided by NPR, Copyright NPR.
