TuC2.1 - PNT OPEN ARCHITECTURES – THE PATHWAY TO PHOTONIC-BASED SENSOR INTEGRATION
Abstract
Abstract
This talk focuses on the DoD’s desire to develop and own a PNT Open System Architecture that incorporates the latest technology trends for navigating in difficult urban, indoor, and underground environments where typical Global Positioning System (GPS) receivers do not function. Photonic based sensors offer very promising capabilities, but the ability to quickly and reliably integrate these technologies in today’s closed systems in expensive and takes too long.TuC2.2 - COMPACT PASSIVE MILLIMETER WAVE IMAGER FOR DEGRADED VISUAL AND GPS-DENIED NAVIGATION

Abstract
Abstract
We present a passive millimeter wave imager for aerial vehicle navigation in degraded visual and GPS-denied environments. The sensor employs aperture synthesis imaging techniques with optical upconversion of millimeter wave signals and coherent reconstruction in the optical domain to enable a suitably small form factor.
TuC2.3 - ENABLING SIMULTANEOUS TRANSMIT AND RECEIVE WITH OPTICAL INTERFERENCE CANCELLATION
Abstract
Abstract
We demonstrate an optical filter to cancel 20 dB of various multipath self-interference components over a multioctave 600 MHz band centered around 400 MHz. This enables significant gains in transceiver effectiveness by enabling Simultaneous Transmit and Receive (STAR).
TuC2.4 - NAVIGATION IN GPS-DENIED ENVIRONMENTS VIA SKYLIGHT POLARIZATION PATTERNS
Abstract
Abstract
Low-power GPS signals are easily jammed, making it crucial to evaluate complementary technologies which can provide geolocation information in GPS-denied environments. We introduce the concept of skylight polarization-based navigation and evaluate the feasibility of this new technique.
