Navigation of aircraft using the crustal magnetic field variation of the earth is a novel and developing technique for use in GPS-denied environments. Location estimation is accomplished by matching the magnetic field measurements in flight to a specific track on a magnetic map of the globe. Atomic scalar magnetometers are ideally suited for use on aircraft because they are not sensitive to aircra ...

We propose a two year program to develop an atomic vector magnetometer to replace standard commercial fluxgate magnetometers in use by the US Navy. Thousands of fluxgate magnetometers are used to measure ship magnetic signatures and they are often limited by low frequency drift. An vector magnetometer based on atomic spin will have significantly improved drift. The alkali metal atomic vector magne ...

Growing amounts of text and visual files are being stored in document archives at organizations' servers, network attached storage devices and cloud storage services. These archives contain valuable information that is not cataloged in a data-driven manner conducive to discovery.  Under an SBIR Phase II effort, Semandex developed Discovery, a cloud-based application that uses Natural Language Pro ...

Under SciTec’s Atmospheric InfraRed Transmittance Calculator (AIRTraC) Small Business Innovative Research (SBIR) effort, we developed a software application to perform autonomous ingest and fusion of available atmospheric profile data with that collected by a ground-based meteorological station to improve the atmospheric correction process for remotely sensed data. SciTec extends this previous w ...

Stealth communications is difficult. RF, including spread spectrum, illuminates, and thus can be used to locate transmitters. Further, RF is blocked by buildings, heavy foliage, water and it can be jammed and/or spoofed. This Static Magnetic Communications (SMC) concept uses vector magnetometer technology to read the change in field strength of a spinning permanent magnet modulated by a mu-metal c ...

The cockpits of current day aircraft are filled with radio frequency (RF) signals and electromagnetic (EM) fields. However, tittle is known of the RF/EM field characteristics or potential impacts of these fields on aircrew physiology and cognitive performance. This study proposes to measure pilot cognition will in a simulated flight environment with EM/RF fields analogous to the cockpit of a milit ...

Non-compressible torso hemorrhage (NCTH) is the leading cause of death among survivable battlefield injuries. These types of hemorrhages result from bleeding that cannot be controlled with a tourniquet or application of direct pressure. Additionally, within the civilian US sectors, bleeding from trauma creates a significant death toll among survivable injuries.   With the advent of resuscitative ...

Military cockpits are flooded with multiple RF/EM signals and noise of varying frequencies and amplitudes.  Little is known, however, of the actual impacts of these fields on pilots, as no monitoring is currently performed. Consequently, no efforts have been made to shield pilots from these fields.  To address these unknown impacts on aircrew cognitive performance, Spotlight proposes to fully ch ...

MaXentric proposes the GAU2x2 wideband power amplifier system. The design combines MaXentric’s wideband RF PA technology with advanced digital signal processing in a single small footprint package. This tight integration is made possible through the extremely high efficiency and low power dissipation. Since very little power is dissipated as heat, the package and heat sink size can be minimized. ...
