Rescuing crew that have fallen overboard in bad weather is fraught with difficulty. Handling the boat and returning to a position close enough to the person is not always easy, especially when operating under stressful conditions. A new system proposes to use satellite navigation to locate the precise position of casualties, and ultimately save lives. Peter Hall and Christine Edwards, both of British start-up company Sci-Tech Systems, have come up with a scheme to help save lives using the...

Just like flat-screen televisions, cell phones and computers, global positioning system (GPS) technology is becoming something people can't imagine living without. So if such a ubiquitous system were to come under attack, would we be ready? It's an uncomfortable question, but one that a group of Cornell researchers have considered with their research into "spoofing" GPS receivers. GPS is a U.S. navigation system of more than 30 satellites circling Earth twice a day in specific orbits,...

LONDON, Ohio -- Aided by a computer and a Global Positioning System - a constellation of Earth-orbiting satellites - a farmer's tractor can now drive itself. The use of such technology has increased in the past few years as farmers try to cut costs to stay profitable as crop prices remain relatively stagnant. Infrared sensors control how much fertilizer is applied. Retinal imaging tracks cattle. On the horizon, perhaps, are tomato-picking robots. Experts estimate that up to 15 percent of...
