The military relies heavily on the Global Positioning System (GPS) for positioning, navigation, and timing (PNT), but GPS access is easily blocked by methods such as jamming. In addition, many environments in which our military operates (inside buildings, in urban canyons, under dense foliage, underwater, and underground) have limited or no GPS access. To solve this challenge, Adaptable Navigation Systems (ANS) seeks to provide GPS-quality PNT to military users regardless of the operational environment.
Defense forces rely on electromagnetic dominance for command, control, intelligence, surveillance, reconnaissance, and related applications that use the electromagnetic spectrum. Similarly, spectrum use by our adversaries, coupled with extensive commercial use, yields an increasingly congested space, time and frequency environment.
The “Science of Atomic Vapors for New Technologies” (SAVaNT) program aims to significantly advance the performance of atomic vapors as a room-temperature (RT) platform for enabling new technologies in the areas of electric field sensing and imaging, magnetic field sensing, and quantum information science (QIS).
