As the Air Force moves toward the deployment of many smaller satellites, it would be useful to develop smaller versions of SSUSI and GUVI imagers to take advantage of these multiple platforms, so that global measurements could become an operational reality. The goal of the Phase I effort proposed… More

We propose to investigate under Phase-I of the STTR Program FY07 the development of space weather sensor networks including the next-generation of GPS space weather monitors, the network interfaces for internet and remote operation, and system-wide analysis algorithms to validate and calibrate the… More

Accurate real-time knowledge of the bottomside ionosphere is necessary for covert HF communications, near vertical incidence sounding, and geolocation of HF transmitters. Sky-wave TDOA geolocation is the "holy grail" of HF geolocation techniques due to its passive nature, low cost, and easy… More

As the Air Force moves toward the deployment of many smaller satellites, it would be useful to develop smaller versions of SSUSI and GUVI imagers to take advantage of these multiple platforms, so that global measurements could become an operational reality. The goal of Phase II shall be to develop… More

This Phase-II proposal addresses Air Force STTR Topic AF07-T031 (Robust, Autonomous, Inexpensive Space Weather Sensors), which was released with the objective to develop robust, autonomous, low-cost sensors to deliver near real-time, three-dimensional space environmental data. The Air Force requires… More

This Phase-I proposal applies Plug-and-Play concepts to the development of a radically new instrument, the so-called CubeSat-Tiny Ionospheric Photometer (CTIP) that will acquire 135.6 nm nightglow measurements with optical design, thermal management, and power control systems specifically… More

ABSTRACT: Satellite drag is the leading cause of orbit prediction error in low earth orbit. Modeling of this drag force and its variability is critical to accurate orbit determination and prediction. One of the leading contributing factors to error in drag prediction is thermospheric neutral… More

ABSTRACT: The Air Force and other DoD components require accurate knowledge of the ionospheric environment to understand and predict its impacts on vital radio-based systems, including communications, navigation, and surveillance systems. ASTRA proposes the"GAMMA"GPS autonomous… More

ABSTRACT: The Air Force and other DoD components require accurate knowledge of the ionospheric environment to understand and predict its impacts on vital radio-based systems, including communications, navigation, and surveillance systems. In response to the STTR Topic AF112-083 we propose to… More

ABSTRACT: Accurate specification of the ionospheric environment is critical to Air Force and DoD needs, because it impacts communications, navigation and surveillance systems. Most current ground-based ionospheric monitoring systems are expensive, large, and power-hungry providing poor coverage… More

ABSTRACT: The ionosphere and upper atmosphere play a major role in Air Force and DoD missions, including communications, navigation, surveillance, and satellite drag. Understanding how the ionosphere affects these DoD missions is tied in part to understanding its motion and variability.… More

ABSTRACT: As the Air Force moves toward the deployment of CubeSats and the need for responsive launches, operational Plug-and-Play instruments to monitor the space environment become necessary. The goal of Phase-II is to develop and deliver a prototype for a new UV remote sensing instrument for… More
