Harnessing Terrestrial and Space-Based mmWave Signals for Resilient and Accurate Positioning, Naviga
Abstract
0000,Harnessing Terrestrial and Space-Based mmWave Signals for Resilient and Accurate Positioning, Navigation, and Timing (PNT)We propose, to acquire state-of-the-art equipment and instrumentation to harness terrestrial and space-based millimeter-wave (mmWave) signals f,or resilient and accurate positioning, navigation, and timing (PNT). Future DoD operations will increasingly take place in environme,nts where GPS signals are denied or challenged. To enable resilient and accurate PNT in these environments, the PI pioneered a trans, the environment, performing multi-radio simultaneous localization, timing extraction, and signal landscape mapping. In this framewo,rk, a radio eavesdrops on unknown ambient radio frequency (RF) signals of opportunity (SOPs), such as cellular, television, and sate,lly fused to (1) build a spatiotemporal signal landscape map of the RF environment within which the radios simul- taneously localize, themselves in space and time and (2) aid the inertial navigation system (INS) in a tightly-coupled fashion. The drawn information i,s also shared among multiple radios over communication networks when available.The current PNT paradigm will not meet the demands of, future manned and unmanned intelli- gence, surveillance, and reconnaissance and weapon systems to operate in highly-contested elec-, tromagnetic environments. The current PNT paradigm is non-networked, signal-similar, inflexible, and is ultimately traced to weak G,PS signals from a single satellite constellation. GPS has become a single point of failure in the current PNT paradigm. Our COpNav f,ramework addresses the limitations of the current PNT paradigm. COpNav will make PNT systems of future manned and unmanned air, surf,ace, and ground platforms and forces robust and accurate when GPS signals become compromised. COpNav has been demonstrated to achiev,e meter- and submeter-level ac- curate navigation on ground and aerial vehicles, respectively, by exploiting ambient terrestrial and, low Earth orbit (LEO) satellite signals. In fact, our achieved navigation results are the most ac- curate among all published liter,ature, by an order of magnitude. However, to date, the signals we have exploited have been in the very high frequency (VHF) and ultr,a high frequency (UHF) bands. Future terrestrial (e.g., fifth-generation (5G) cellular) and space-based (e.g., upcoming LEO con- ste,llations) communication systems are tapping into the extremely high frequency (EHF) bands, i.e., mmWave. The proposed mmWave opportu,nistic navigation system (mONS) testbed will be the first-of-its-kind in research aimed at harnessing terrestrial and space-based mm, be deployed in multiple configurations: (1) as a stationary ground station, (2) on a ground vehicle, (3) on manned and unmanned aer,ial vehicles, (4) on a marine vehicle, or (5) a combination thereof.The proposed mONS testbed will have immediate and profound impac,ts on ongoing DoD- funded research programs and collaborations with nearby Naval and Air Force bases: Naval Sur- face Warfare Center, Corona (NSWC-Corona), Naval Information Warfare Center Pacific (NIWC- Pacific), Edwards Air Force Base, and Marine Corps Base Camp,Pendleton. In addition, with the mass deployment of 5G technology worldwide and the new space race to launch thousands of LEO satell,ites, the mONS testbed is timely and would enable revolutionary future research opportunities in mmWave technology. What is more, th,e mONS testbed will have major educational impacts, which will create a knowledgeable workforce by training undergraduate and gradua,te students as well as engineers from
