Microwave Limb Sounder

A process for separating chemical compounds in fluids resulted from a Jet Propulsion Laboratory (JPL)/LAPD project. The technique involves pouring a blood or urine sample into an extraction tube where packing material contained in a disposable tube called an extraction column" absorbs water and...

This code is integral to generating products for the currently active UAVSAR sensor/program. Repeat pass radar interferometry is integral to current geophysical research as it provides the only technique possible of obtaining highly accurate (millimeter level) and spatially dense surface...

The PDG (Powered Descent Guidance) algorithm and software for computing Mars pinpoint or precision landing guidance was enhanced with options to constrain the maximum allowable speed and the allowable attitude profiles. The speed constraints were added as an option to ensure that velocity profiles...

A number of iRobot employees have drawn from their NASA experiences to help develop the PackBot Tactile Mobile Robot, used by U.S. troops in Iraq and Afghanistan to help clear caves and bunkers, search buildings, and cross live anti-personnel mine fields. The chief executive officer of iRobot...

Phase retrieval (PR) and Shack-Hartmann Sensor (SHS) are the two preferred methods of image-based wavefront sensing widely used in various optical testbeds, adaptive optical systems, as well as ground- and space-based telescopes. They are used to recover the phase information of an optical system...

The algorithm was developed to run in an FPGA at input data sampling rates of up to 1280 MHz. The current implementation takes a 1280 MHz real input and first breaks it up into seven 160 MHz complex channels each spaced 80 MHz apart. The eighth channel at baseband was not required for this...

BEEM (Ballistic Electron Emission Microscopy) was invented at Jet Propulsion Laboratory's Center for Microelectronics Technology. It is a significant research instrument for microelectronics research because it is able to image underlying layers or interfaces of surface structures. A tiny current...

A NASA-developed computer program has effected substantial savings in inclined orbit trackings for Research Concepts, Inc. Artificial Satellite Analysis Program (ASAP) allowed the company to avoid duplicating research and shortened the time needed to develop an R2000B antenna controller. The device...

SeaSpace Corporation, of Poway, California, worked with NASA's Jet Propulsion Laboratory under two SBIR contracts to reduce the cost of satellite ground tracking. The resulting hardware and software not only complement NASA's remote sensing capabilities but also benefit the greater research...

A mineral identification tool developed for NASA's Mars Rover Technology Development Program is now serving as a powerful tool for U.S. law enforcement agencies and military personnel to identify suspicious liquid and solid substances. The Jet Propulsion Laboratory awarded a Small Business...
