Adaptable Navigation Systems (ANS)
Abstract
The Adaptable Navigation Systems (ANS) program provided the U.S. warfighter with the ability to effectively navigate challenging environments including when Global Positioning System (GPS) is unavailable due to hostile action (jamming) or blockage by structures, foliage, or other environmental obstacles. The ANS approach relied on three major technology innovations. The first was the development of a new type of inertial measurement unit (IMU) that required fewer GPS position fixes. Using cold atom technology, this IMU exceeds the performance of strategic-grade IMUs, with comparable size, weight, and power (SWaP). The second innovation used Signals of Opportunity (SoOp) from a variety of ground-, air-, and space-based sources, as well as natural SoOps to reduce dependency on GPS position fixes. The third technology innovation allowed SoOp-based position information to be combined with inertial and other sensors to enable flexible navigation systems that can be reconfigured in the field to support any platform or environment. This capability enhanced new advanced component technology for positioning, navigation, and timing (PNT) emerging from other programs in the form of Micro Electro-Mechanical System devices, clocks, and new aiding sensors. Recent advances in mathematics, data abstraction, and network architectures built upon these capabilities by enabling "plug-and-play" integration of both existing and future navigation components and processing to allow real-time reconfiguration of navigation systems. Major improvements in navigation accuracy and system cost were also realized. Potential transition partners include all Services, with emphasis on platforms and users that must operate in multiple environments, such as Naval forces.
