A Collaborative Opportunistic Framework for Resilient and Accurate Navigation in GPS-Challenged Environments
Abstract
Approach:The performer will conduct research to enable resilient and accurate positioning, navigation, and timing (PNT) in environments where Global Positioning System (GPS) signals are denied or challenged. This research will develop a coherent analytical foundation, a suite of algorithms and tools, and software and hardware prototypes for an innovative PNT framework in which a radio draws opportunistically from ambient radio frequency (RF) signals of opportunity (SOPs) relevantpositioning and timing information. The drawn information is synergistically fused in a tightly coupled manner to build a global signal landscape map of the environment within which the radio simultaneously localizes itself in space and time. The drawn information is also shared among multiple radios over communication networks when available. Collectively, we refer to the proposedapproach as Collaborative Opportunistic Navigation (COpNav).Objective:The proposed research addresses the Navy~s high-priority objective of reliable and accurate non-GPS navigation. Our proposed research aims to (1) establish foundational theory and abstraction methods for COpNav, (2) synthesize optimal collaborative navigation filtering architectures, (3) develop a suite of algorithms and tools to characterize the achieved PNT performance in various practical situations, (4) develop practical and powerful detection tests to determine the integrity ofreceived SOPs, (5) optimize the PNT performance via multi-radio collaboration and motion planning, and (6) develop a testbed for experimental verification of our COpNav framework.Naval Relevance:The proposed research addresses the Navy~s high-priority objective of reliable and accurate non-GPS navigation. The proposed research will make PNT systems of future unmanned and manned Naval air, surface, and ground platforms and forces more resilient and accurate in situations where GPS signals get compromised.
