Default U.S. sends drones to Libya as battle rages for Misrata

Reuters - Found 2 hours ago
MISRATA, Libya - The United States has started using armed drones against Muammar Gaddafi's troops, who battled rebels at close quarters on the streets of Misrata, despite Western threats to step up a month-old air war. Rebels welcomed the deployment of U.S. unmanned aircraft and said they ...

New kinda drone...

Japanese inventor develops sphere drone
Sat, Aug 06, 2011 - A Japanese defense researcher has invented a spherical observation drone that can fly down narrow alleys, hover on the spot, take off vertically and bounce along the ground.
Quote:
About the size of a beachball and jet black, the remote--controlled Spherical Air Vehicle resembles a tiny Death Star from the Star Wars movies, but has a more benign purpose — to transmit live images from a video camera. It is powered by a propeller protected by a spherical shield with large openings for airflow, meaning a knock into a wall or a tumble to the ground will not damage it. Research to improve the device is continuing, but its designer says that in the future it could be used as a formidable pursuit vehicle that can travel above traffic or spy on a target through a window.


Advanced Defense Technology Center Engineer Fumiyuki Sato displays his spherical observation drone in Tokyo on July 22.

Its inventor in pacifist Japan hopes it could also help with non-aggressive operations, such as search and rescue in disaster zones, where it could fly through buildings and even up and down stairways. “This is the world’s first spherical air vehicle,” said its developer, Fumiyuki Sato, a research engineer at the Japanese Defense Ministry’s Technical Research and Development Institute in Tokyo. The latest model, the seventh prototype, is equipped with a single propeller that is shielded by the shell, with flaps and wings to -control its flight, and can zip through the air at speeds of up to 60kph.

Sato said all its components can be found in shops in Tokyo’s electronic tech-geek heaven of Akihabara, at 100 stores where every item sells for about US$1, or on the Internet. The motor at the core is contained by a modified plastic -bottle, and the total cost for the parts come to ¥110,000 (US$1,400) for the latest model, which weighs just 350g and has a diameter of 42cm. Sato says that many hurdles remain before the flying sphere can be put to practical use, including adding an autopilot function and finding ways to cope with turbulence and poor weather conditions.

Drones vulnerable to terrorist hijacking, researchers say
June 25, 2012 - A small surveillance drone flies over an Austin stadium, diligently following a series of GPS waypoints that have been programmed into its flight computer. By all appearances, the mission is routine.
Quote:
Suddenly, the drone veers dramatically off course, careering eastward from its intended flight path. A few moments later, it is clear something is seriously wrong as the drone makes a hard right turn, streaking toward the south. Then, as if some phantom has given the drone a self-destruct order, it hurtles toward the ground. Just a few feet from certain catastrophe, a safety pilot with a radio control saves the drone from crashing into the field. From the sidelines, there are smiles all around over this near-disaster. Professor Todd Humphreys and his team at the University of Texas at Austin's Radionavigation Laboratory have just completed a successful experiment: illuminating a gaping hole in the government’s plan to open US airspace to thousands of drones.

They could be turned into weapons. “Spoofing a GPS receiver on a UAV is just another way of hijacking a plane,” Humphreys told Fox News. In other words, with the right equipment, anyone can take control of a GPS-guided drone and make it do anything they want it to. “Spoofing” is a relatively new concern in the world of GPS navigation. Until now, the main problem has been GPS jammers, readily available over the Internet, which people use to, for example, hide illicit use of a GPS-tracked company van. It’s also believed Iran brought down that U.S. spy drone last December by jamming its GPS, forcing it into an automatic landing mode after it lost its bearings.

While jammers can cause problems by muddling GPS signals, spoofers are a giant leap forward in technology; they can actually manipulate navigation computers with false information that looks real. With his device -- what Humphreys calls the most advanced spoofer ever built (at a cost of just $1,000) -- he infiltrates the GPS system of the drone with a signal more powerful than the one coming down from the satellites orbiting high above the earth. Initially, his signal matches that of the GPS system so the drone thinks nothing is amiss. That’s when he attacks -- sending his own commands to the onboard computer, putting the drone at his beck and call.

Humphreys says the implications are very serious. “In 5 or 10 years you have 30,000 drones in the airspace,” he told Fox News. “Each one of these could be a potential missile used against us.” Drones have been in widespread use in places like Iraq, Afghanistan and Yemen, but so far, GPS-guided unmanned aerial vehicles have been limited to the battlefield or southern border patrols and not allowed to fly broadly in U.S. airspace.
