GPS System That Works Indoors

GPS Trackers Could Get Even More Accurate

GPS fleet management systems and personal tracking devices are some of the most accurate monitoring solutions on the market. When used in ideal conditions these GPS devices can routinely pinpoint the location of a person or object within roughly 2.5 meters. In fact, personal GPS devices can determine the exact house a person is in and vehicle tracking devices can show what parking space a car is occupying! There is no denying satellite technology has revolutionized the way many businesses operate and how families enhance personal safety measures, but GPS still has many limitations. For example, concrete and metal block low level GPS signals which makes it impossible to determine where a person is located inside of buildings and other infrastructure. However, that may all change if a company called InvenSense finalizes development of a GPS solution that utilizes barometric chips in their tracker devices.

GPS tracker devices are highly accurate in outdoor environments where wide streets are present and urban canyons are not causing interference. The problem is that in major metropolitan areas, such as those commonly found in places such as New York, GPS can be substantially inaccurate. This accuracy only gets worse if the user is inside of a building. Even with the limitations of GPS always being a hurdle, InvenSense plans on developing chips that will allow smart phones to navigate their users regardless of environment and conditions that cause GPS not to work. What the technology company gave a sneak peek of at the 2013 Consumer Electronics Show is a new form of monitoring solution that utilizes electronic barometers capable of detecting changes in altitude. In fact, these barometers will be so sensitive that the company stated they will be able to notice changes as small as a person standing up from a chair! But the most impressive thing is that trackers will be able to detect these minor movements in subway stations, inside buildings and more. Through the combination of  barometric chips capable of detecting the slightest changes in altitude with sensors that can monitor motion, the potential for this new technology is limitless. What is even more impressive is that developers believe that in time the technology will be accurate to the sub-meter and potentially be able to determine if a person is sitting or standing up! Only time will tell if InvenSense will be able to follow through with their intriguing claims, but one thing is certain and that is if they are successful that the entire playing field for location based services will have changed. Smart phones capable of guiding users through locations where GPS signals falter could open the door to a number of new applications and new level of oversight. News Source: Reuters
