We develop Flight Deck (FD) and Airline Operational Control (AOC) Decision Support Tools (DSTs) for strategic guidance to pilots for mitigating encounters with en route weather hazards. Implemented on either Commercial Off-The-Shelf (COTS) Electronic Flight Bags (EFBs) or Personal Electronic Devices (PEDs), the system is designed to increase the likelihood of Air Traffic Control (ATC) approval of ...

We build a software system that executes a virtual marketplace for urban air mobility (UAM). The virtual marketplace will serve the traveling public with an on-demand system that connects multi-modal modes of transportation in a competitive marketplace environment utilizing forward auctions and reverse auctions to provide cost effective transportation of people and goods. The virtual marketplace ...

The current generation of spacecraft and terrestrial water recovery technologies are often prone to failures caused by biofouling and mineral scaling, which can clog mechanical systems and degrade the performance of capillary-based technologies. These failures require expensive and time-consuming maintenance and resupply, and the technologies are therefore limited to environments where these resou ...

Nearly all fluid systems aboard spacecraft are, or become, multiphase fluid systems, whether by design or default. Unfortunately, we still do not possess ample understanding of low-g fluid phenomena to assure performance and avoid system failure. Though inadequate fluid system design can lead to disastrous consequences, for the most part, and for life support systems in general, precious crew time ...

To address NASA’s need for next-generation spaceborne lidar systems for aerosol, cloud, and ocean profiling, Voxtel is developing a low-noise high-efficiency high-dynamic-range photon-counting (HiP) sensor. The HiP sensor is based on silicon single-photon avalanche diode (SPAD) technology and is capable of both atmospheric and ocean profiling, essentially enabling the first-ever ocean-profiling ...

Seven miniature cathodes are offered in unique support and discharge structures with heaters and in keeper assemblies for use in thrusters for small satellites and CubeSats. Cathode candidates include LaB6, hafrium carbide, scandate, barium oxide coated tungsten, thoriated tungsten, tantalum and yttria-coated iridium. Each cathode will be constructed, tested, and evaluated in a xenon and iodine di ...

A receiver system for use in LIDAR consisting of an optical filter and optical spectrometer based upon two-photon absorption is proposed. The filter and spectrometer both use dispersion from excited state transitions of atomic rubidium to create a birefringent medium. The birefringent medium of the optical filter rotates the polarization of light so that it is transmitted through crossed polariz ...

A hollow reservoir cathode for use in ion and Hall thrusters which uses iodine as propellant. Reservoir cathodes have unique features not found in conventional impregnated cathodes. The critical barium reduction process occurs in the reservoir, not in the matrix, and this isolates that process from iodine poisoning. Also, the barium supply is 100 times greater than is available in conventional cat ...

For the purposes of supporting planned and future NASA missions and addressing an unmet NASA need for high-quality visible through shortwave-infrared telescope phase-correction optics manufactured and delivered quickly and inexpensively, Voxtel proposes a Phase II effort to develop a new class of three-dimensional freeform optics and to demonstrate the optical precision and size reduction possible ...

This SBIR system is a machine learning system that uses a very large database of airside and landside data to predict pushback and takeoff times of aircraft at a given airport. Airside data sources describe the state of the system after TSA security screening is complete, and includes information about the crew and passengers arriving at the departure gate, turnaround and pushback preparation, ra ...
