This is the second in a two-part series () of works-in-progress articles taken from a special session, which was part of the Cluster Computing and Grid 2005 conference (http://www.cs.cf.ac.uk/ccgrid2005), held in Cardiff, UK. The session was organized by Mark Baker (University of Portsmouth, UK) and Daniel S. Katz (Jet Propulsion Laboratory, US). For more information, you can contact the sessio...

The Advanced Communications Technology Satellite (ACTS) Mobile Terminal (AMT) is a proof-of-concept K/Ka-band mobile satellite communications terminal under development by NASA at the Jet Propulsion Laborato~. Currently the AMT is undergoing system integration and test in preparation for a July 1993 ACTS launch and the subsequent commencement of mobile cxpcrimcnts in the fall of 1993. The AMT o...

A series of four test flights of the SPHERES formation flying testbed was conducted aboard NASA’s KC-135 micro-gravity airplane in November 2003. These tests were sponsored by the Jet Propulsion Laboratory in Pasadena, CA, through the Terrestrial Planet Finder program, with the goal of advancing the progress of the SPHERES-TPF project prior to launch of the testbed to the International Space St...

NASA Tech Briefs, November 2010 yield this behavior. Previous work on mean-square error characterization for ML estimators has predominantly focused on additive Gaussian noise. This work demonstrates that the discrete nature of the Poisson noise process leads to a distinctly different error behavior. This work was done by Baris I. Erkmen and Bruce E. Moision of Caltech for NASA’s Jet Propulsion...
