[SatNews] 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.
Indoor tracking systems which process data from one or more sources of location information to estimate where a person or object is located are not new. But they often rely on RF signals from wi-fi access points or custom infrastructure, poor-quality GPS signals or expensive, high-quality sensors. The availability of low-cost smartphone components—including accelerometers, gyroscopes, magnetometers and pressure sensors—has enabled a new generation of location devices and applications, when combined with a tailored Bayesian algorithm to fuse the information. The new technology platform can be embedded in an existing design or operate as a stand-alone unit, with options to compute the location locally or transmit the information to a remote system which can process the data before visualizing it on a smartphone app.
Cambridge Consultants specializes in developing low-cost, low-power connected devices for clients—with a team of experts with sensing, wireless and software engineering expertise. The latest technology builds on the company’s tracking and location systems experience in a variety of market sectors ranging from defense and security to consumer, industrial, and oil and gas.
