Electrical checkout and testing is a critical part of the overall space integration and test flow. Verifying proper harness and connector signal interfaces is key to ensuring component health and overall system functionality. Break-out boxes (BOBs) are used to give test...

The innovation is a technique to overcome hardware limitations of common high-speed data acquisition systems in order to be able to measure electronic signals with high dynamic range, wide bandwidth, and high frequency.

Optical combs generated by a monolithic resonator with Kerr-medium can be used in a number of applications, including orbital clocks and frequency standards of extremely high accuracy, such as astronomy, molecular spectroscopy, and the like. The main difficulty of this approach...

A four-element array conformed to a singly curved conducting surface has been demonstrated to provide 2 dB axial ratio of 14 percent, while maintaining VSWR (voltage standing wave ratio) of 2:1 and gain of 13 dBiC. The array is digitally controlled and can be scanned with the LMS Adaptive Algorithm...

The R4SA GUI mentioned in the immediately preceding article is a user-friendly interface for controlling one or more robot(s). This GUI makes it possible to perform meaningful real-time field experiments and research in robotics at an unmatched level of fidelity, within minutes of setup. It provides such powerful...

Stroboscopic interferometry is a technique for measuring the modes of vibration of mirrors that are lightweight and, therefore, unavoidably flexible. The technique was conceived especially for modal characterization of lightweight focusing mirror segments to be deployed in outer space;...
