SaraniaSat provides actionable remote-sensing data and information products primarily to agricultural customers. Remote-sensing data is acquired through customized and proprietary drone/aircraft/satellite platforms and processed using SaraniaSat's high-performance algorithms. The resulting actionable information has high spatial, spectral and temporal resolution.
Atmospheric Optical Turbulence Monitoring and Prediction
Guidestar’s atmospheric optical turbulence sensing technology remotely measures atmospheric turbulence strength. Guidestar uses these measurements in combination with a proprietary model to estimate a number of localized weather parameters to support operational decision making. In addition, Guidestar’s model can use weather forecast data to predict atmospheric optical turbulence.
Pulse tube refrigerator with tunable inertance tube
AFRL has developed an inertance tube for a pulse tube refrigerator which can be tuned to optimize performance. Apertures in the inertance tube fluidly communicate the inertance tube with a fluid reservoir.
Seeded Raman amplifier in linear configuration for laser applications in the 1100-1500 nm spectral range
AFRL has developed a Raman amplifier having a novel design enabling high Raman conversion efficiencies and output powers in addition to linewidths, which can be controllable by a seed source. In this technology, a rare-earth-doped Raman amplifier can be spliced directly onto a Raman resonator system. To increase the efficiency of the system, a highly reflective Bragg grating centered at the pump wavelength can be included downstream from the Raman fiber to enable reflection of any unused pump light back through the Raman fiber. This offset can be accomplished in various ways to include temperature, bending, stretching, etc.
Pseudomorphic glass for space solar cells
AFRL has developed a flexible hybrid cover glass for spacecraft solar panels comprised of small beads of either fused silica or ceria-doped borosilicate glass embedded in a matrix of conventional cover glass adhesives. These beads may also be used in a matrix of Kapton as the solar panel's substrate which may be combined with flexible solar cells to form flexible solar panels.
Deployable space boom using bi-stable tape spring mechanism
AFRL has developed a spacecraft deployment mechanism employing a pair of bi-stable tape springs attached to a cylinder such that rotation of the cylinder extends or retracts the tape springs in opposite directions
Sensor assemblies using redundant two-dimensional detector arrays
AFRL has developed a sensor assembly that replaces a single focal plane array detector with two focal plane array detectors orientated with respect to each other such that a power splitter divides an incoming light source equally between each detector.
Lightweight acoustic damping treatment
AFRL has developed a flexible membrane attached to an internal wall of the fairing of a flight vehicle. The membrane is inflated with gas to achieve a shape that couples with and thereby attenuates the first acoustic resonance occurring within the volume enclosed by the fairing. Based on the sensed ambient atmospheric pressure, this system adjusts the membrane's gauge pressure throughout the flight trajectory to maintain the desired coupling gauge pressure.
