Domestic Drones on Patrol

Drones: A Booming Business?: Unmanned aerial vehicles, also known as drones, may soon become commercialized. In Grand Forks, N.D., people are preparing for a coming boom in drones-related business.


GRAND FORKS, N.D. — On the pilot’s computer screen, planted at ground level a few yards

from the airport runway here, the data streaming across the display tracked an airplane at 1,300 feet above a small city on the coast, making perfect circles at 150 miles per hour.
To the pilot’s right, a sensor operator was aiming a camera on the plane to pan, tilt and zoom in a search among the houses on the ground for people who had been reported missing.
On his screen, cartoonlike human figures appeared in a gathering around a camp fire between the houses.
“There they are,” Andrew Regenhard, the pilot and a student, said in a flat tone that seemed out of place with a successful rescue mission.

In fact, no one was missing; the entire exercise used imaginary props and locales. Mr. Regenhard was taking part in a training session at the University of North Dakota. The first to offer a degree program in unmanned aviation, the university is one of many academic settings, along with companies and individuals, preparing for a brave new world in which cheap remote-controlled airplanes will be ubiquitous in civilian air space, searching for everything from the most wanted of criminal suspects to a swarm of grasshoppers devouring a crop.
“The sky’s going to be dark with these things,” said Chris Anderson, the former editor of Wired, who started the hobbyist Web site DIY Drones and now runs a company, 3D Robotics, that sells unmanned aerial vehicles and equipment. He says it is selling about as many drones every calendar quarter — about 7,500 — as the United States military flies in total. ...

The rapidly expanding market has not gone unnoticed by lawmakers and privacy watchdogs. On Wednesday, the Senate Judiciary Committee will hold a hearing on the privacy implications of drones like the ones being developed at Grand Forks.

Senator Patrick Leahy, the Vermont Democrat who is chairman of the committee, said this year: “This fast-emerging technology is cheap and could pose a significant threat to the privacy and civil liberties of millions of Americans. It is another example of a fast-changing policy area on which we need to focus to make sure that modern technology is not used to erode Americans’ right to privacy.”
Some fans of the technology wince at the word “drone,” which implies that there is no pilot. And they have grown resentful about the alarms raised over privacy issues, noting that a few city and state governments have begun banning drones even where they do not yet operate.

Tom K. Kenville, chairman of the North Dakota chapter of the trade association, Unmanned Applications Institute, International, said such bans would discourage technological progress. “I don’t think we had rules for the road before we had roads,” he said.
Back in the university lab, Rico Becker, a software developer with Corsair Engineering, which had written a program for the students, emphasized that the “missing persons” exercise was just one of many hypothetical missions that students would fly, and was purely theoretical. “We’re not training pilots to spot people camping in their backyards,” he said. ...
Volunteer fire departments in places like Grand Forks, Mr. Kenville said, would provide a clear market. An unmanned vehicle, he said, was “going to beat all the cars there,” to determine the scope of a problem.
“If it’s a chemical fire, it will tell us to stay away, or it’s just some hay bales, drive slower,” he said. ...

“This is money,” said Matthew L. Opsahl, in another part of the University of North Dakota simulation lab, at a work station where an operator could coordinate the activities of several remotely operated planes. One person could handle six cargo planes at a time, he said, or direct ground-based crews of several remotely operated planes that were scanning a large-scale event, like a spreading forest fire. The operator could compare the aerial images with those from Google maps, identifying street names and addresses to forward to a 911 call center.
Mr. Opsahl, a former pilot on a regional jet, is now an instructor in the North Dakota program, where Mr. Regenhard, 21, a junior from Prescott, Wis., has a double major in commercial aviation and in unmanned aerial systems. Mr. Regenhard is also building a six-rotor helicopter that will beam pictures back to the ground, one that might inspect rooftop air-conditioners or offer a bird’s-eye view of a crime scene. ...
The unresolved question is how to avoid midair collisions, because the operator on the ground cannot see other traffic in the air. The F.A.A. plans to have a system ready by 2015 called “sense and avoid” in which each plane in the sky, manned or unmanned, uses GPS equipment to locate itself, and sends that information to a computer on the ground that draws a map showing all targets. The computer then rebroadcasts that map to every pilot in the air — or at a computer workstation on the ground, as the case may be.
The progress of electronics seems relentless. Mr. Anderson, of 3D Robotics, said that all the components in a drone — a fast processor, a good battery, a GPS receiver and microelectromechancial sensors — were present in an iPhone. ...
The field is embryonic. “We’re in the Wilbur Wright years of the U.A.S. industry,” said Bruce Gjovig, director of the Center for Innovation, a business incubator, at the University of North Dakota.
Benjamin M. Trapnell, an associate professor and a mainstay of the unmanned aircraft systems program here, ... said the trick was not just in learning to fly such vehicles, but also in designing them, including the cameras or other sensors they could carry, and the ground stations from which they can be controlled.
The technology seems so flexible and promising that even some companies involved in conventional aviation are interested. For example, at Applebee Aviation, which flies 11 helicopters out of Banks, Ore., mostly to spray crops, Warren Howe, the sales manager, said a remotely piloted vehicle might never replace a conventional one for that purpose. In a drone, he said, “you’re limited to looking with a camera; you wouldn’t be able to see necessarily the wind changes that control drift, or a spotted owl or something, or beehives in a neighboring yard.”
“You may not see that kid coming down the street to take a look because he thinks a helicopter is really cool,” Mr. Howe said.
But at the same time, he said, his light helicopters cost $1,100 an hour to charter, and a lot of survey work could be done with a drone instead, mapping out what a manned helicopter would be needed for.
Mr. Anderson, in contrast, said that later this year, his company would introduce a helicopter for agricultural surveillance that would sell for less than $1,000. “That’s not per hour, that’s for the helicopter,” he said.
