As the Army has grown increasingly reliant on GPS, that system has increasingly become the target of enemy intervention.<\/p>\n\n\n\n

GPS can fail due to turbulent weather, bad communications links or enemy attack. The Army is concerned about how troops on patrol can continue to function without GPS, and it is pursuing a range of initiatives to bolster wayfinding for those cut off from the usual means of guidance.<\/p>\n\n\n\n

One effort involves the development of vision-aided navigation technologies. \u201cWe are using camera technology and electro-optic imaging sensors and applying them from a navigational perspective,\u201d said Gary Katulka, a lead engineer for vision-aided tech in the Communications-Electronics Research, Development and Engineering Center\u2018s Command, Power and Integration Directorate\u2019s Positioning, Navigation and Timing Division, or CP&ID PNTD.<\/p>\n\n\n\n

The PNT team is working on systems that combine cameras with inertial measurement units, or IMU, which are made of sensors such as gyroscopes and accelerometers. By joining this sensor data to a camera\u2019s visual feedback, a soldier would be able to navigate effectively, even without GPS.<\/p>\n\n\n\t
