  • Advanced Mico-Gn&C Technology for Low-Cost Planetary 
    Mettler, E.; Chiang, R.; Waddell, P.; Litty, E.; Chang, D.; Bartman, R.; Udomkesmalee, S. (1994--Apri)
    The new NASA paradigm calls for more frequent, low-cost, small spacecraft missions capable of returning high-value planetary science. This challenge also extends to the rapid insertion of advanced technologies across all ...
  • Application of New Technology to Future Celestial Trackers 
    Clark, C.; Eisenman, A.; Udomkesmalee, S.; Tubbs, E. (1995-05)
    New developments in image sensors and optical materials have opened the door to dramatic mass and power reductions in celestial tracker designs. The rapid development of active pixel sensors (APS) has provided a new ...
  • Creating Autonomous Spacecraft with AFAST 
    Udomkesmalee, S. (1995-04)
    Autonomous Feature And Start Tracking (AFAST), essential technology for building autonomous
  • Detection of Planetary Terrain Features 
    Udomkesmalee, S. (1995-04)
    A particular aspect of autonomous target tracking for planetary bodies, detection of "distinct"
  • Image Processing for Planetary Limb/Terminator Extraction 
    Udomkesmalee, S.; Zhu, D.Q.; Chu, C.-C. (1995)
    A novel image segmentation technique for extracting limb and terminator of planetary bodies is proposed. Conventional edge- based histogramming approaches are used to trace object boundaries. The limb and terminator ...
  • Realization of Autonomous Image-Based Spacecraft Pointing Systems: Planetary Flyby Example 
    Chu, C.-C.; Zhu, D.Q.; Udomkesmalee, S.; Pomerantz, M.I. (1995-04)
    The paper summarizes efforts at JPL to develop an intelligent autonomous tracking and pointing system for space applications. A powerful 3D graphic software testbed has also been developed to simulate a likely scenario ...
  • TERA-OPS Processing for ATR 
    Udomkesmalee, S.; Padgett, C.; Zhu, D.; Lung, G.; Howard, A.; Ludwig, D.; Moretti, G. (2000-07-17)
    A three-dimensional microelectronic device (3DANN-R) capable of performing general image convolution at the speed of 10***sup12*** operations/second (ops) in a volume of less than 1.5 cubic centimeter has been successfully ...
