Sunlight polarization patterns may be an underwater substitute for GPS

While GPS can be used to determine one’s geographical coordinates on land, such is not the case underwater. Scientists have developed a possible alternative, however, in the form of a system that analyzes the manner in which sunlight is polarized by wa… Continue reading Sunlight polarization patterns may be an underwater substitute for GPS

Motion-powered GPS unit designed to track wild animals indefinitely

GPS-enabled tracking modules allow scientists to learn a great deal about wild animals, but the devices do have one major drawback – limited battery life. A new tracker gets around that limitation, as it’s continuously powered by the animal’s movements… Continue reading Motion-powered GPS unit designed to track wild animals indefinitely

GPS alternative taps cosmic rays for underground or underwater navigation

GPS is a powerful navigation technology, but it doesn’t work as well inside buildings, underground or underwater. Now engineers in Japan have developed and tested an alternative technology that uses cosmic rays to track movement beneath a building with… Continue reading GPS alternative taps cosmic rays for underground or underwater navigation

Adding Variometer Functionality to a GPS

Flying a glider, or similarly piloting a paraglider or hang glider, can all be pathways into aviation with a lower barrier of entry than powered flight. Sacrificing one’s engine does …read more Continue reading Adding Variometer Functionality to a GPS
