ABSTRACT:The Common Embedded Vehicle Network Diagnostics Interface Hardware (CEVNDIH) program defines and implements an AS5643 optimized IEEE-1394-2008 implementation that includes changes, additions and diagnostic features. Designed with the objective of improving reliability, mission availability and improved affordability of the vehicle it is deployed in, the CEVNDIH removes unused IEEE-1394-20 ...

ABSTRACT:Crossfield proposes to develop a modular rotating data acquisition and signal conditioning device with simultaneous sampling on all channels, up to a 150 kHz flat bandwidth, a 400 kHz sample rate, a 21-bit ADC resolution, noise less than +/- 0.5 percent of full scale, programmable gain from 1 to 10,000, a programmable anti-alias cutoff frequency, scalable to as many as 256 channels, that ...

ABSTRACT:JST proposes a Phase I effort to investigate how the cruise missile air vehicle physical envelope can be repurposed for more flexible missions by incorporating different systems, materials, planforms and operating envelopes. The following key technical issues will be addressed in the Phase I study: 1. Development of a dielectric airframe that will have the structural capability and durabi ...

ABSTRACT:Software Defined Radios rely on digital FPGAs and/or high performance general purpose processors to realize flexible transmitter/receiver solutions that can adapt to various modulation schemes, waveforms, and even mission functions. However, achieving similar flexibility in the complementary RF Front End (RF-FE) poses a much bigger challenge. RF solutions are often designed to specific fr ...

ABSTRACT:Positioning, navigation and timing (PNT) has been a central technology to the armed forces and the Air Force since their inception, and PNTs importance only stands to grow as we forge ahead in the 21st century. Just as todays state of the art PNT harness the quantum states of light in laser based sensors, the next levels of fidelity in both timing and inertial measurement units (IMUs) wil ...

ABSTRACT:Overhead Persistent Infrared (OPIR) sensors are a key part of a developing mission area supported by the Air Force and the Intelligence Community to provide worldwide, persistent surveillance of missile launches and other operations. These sensors operate in the SWIR and MWIR spectral regions. While this spectral range has been valuable for decades to the meteorological community, it is a ...

ABSTRACT:There is a critical need to research and develop new ways to better determine what satellite orbital events are most critical to monitor and how such methods can be made scalable to serve the future needs of the operational system with a growing catalog of up to 500,000 objects. To support this endeavor, Numerica proposes the development of a new software suite for space object conjunctio ...

ABSTRACT:State of art Li ion batteries are not able to meet the energy density and charge-discharge cycling stability requirements for the satellite applications for DoD. The primary problems are the structural instability and the low electronic conductivity of the Li rich transition metal oxide based cathode materials during the charge-discharge cycling operation. Specifically, during the charge- ...

ABSTRACT:As the demand for on-board power and total energy-storage capacity in U.S. Air Force satellites has continued to increase, there has been an increasing trend towards the use of battery technologies with higher energy density potential. To this end, Li-ion batteries are now becoming the new industry standard for use as rechargeable secondary batteries in space vehicles. However, cycle-life ...

ABSTRACT:To meet the current and future power needs of Air Force spacecraft, efficient energy storage systems are necessary to extend mission time, reduce weight, and increase capabilities. Ultracapacitors (also known as supercapacitors or electrochemical capacitors) are paramount in spacecraft applications where pulsed power profiles are expected. Current ultracapacitors have very long cycle life ...
