New technology from innovative product development firm Cambridge Consultants can accurately detect someone’s location indoors when GPS drops out. A number of sensors and a custom algorithm determine the location, with an accuracy of within approximately 1 percent of the distance travelled. Yet the technology uses low-power, low-cost sensors and the device concept is small enough to clip on a belt. It also doesn’t need any existing internal infrastructure.
