In the quest to provide positioning, navigation and timing to troops deprived of GPS, Army planners are developing an open-architecture system of plug-and-play sensors that could deliver such a capability.<\/p>\n\n\n\n

GPS has become an integral part of how the Army operates. But it is increasingly the target of adversaries seeking to deny navigational capabilities.<\/p>\n\n\n\n

The potential PNT solution would use modular hardware and software on a tactical computer.

\u201cIt will be a sensor fusion filter that will allow us to hook up any sensor to the filter, and the filter will understand what the sensor is, what the data is and how to integrate that into a single PNT solution,\u201d said Adam Schofield, the chief at the Emerging Technologies Branch of the Communications-Electronics Research, Development and Engineering Center, or CERDEC.<\/p>\n\n\n\n

In initial tests, the Army is looking for an open framework within which it could combine GPS and inertial measurement units, or IMU, which are made up of sensors such as gyroscopes and accelerometers. In the future, the system would incorporate cameras for visual-aided navigation, as well as other sensors to help determine location and direction.<\/p>\n\n\n\t
