Gyro noise and bias are often performance limitingfactors in space and terrestrial navigation systems, especiallyin cases where no aiding sensors are available. A gyro unitwith good performance in both noise and bias may be veryexpensive and with undesirable SWaP. In this paper,... |

Stewart Sherrit, 2024, "Characterization of surface parallel mirror actuation using preloaded commercial lead zirconate titanate (PZT) stacks", https://doi.org/10.48577/jpl.TWUFCE, SPIE Smart Structures and Nondestructive Evaluation 2024, JPL Open Repository
The next generation of space telescopes will require large, segmented apertures for observations in the near ultraviolet through mid- and far-infrared regions to enable new science ranging from exoplanet characterization to precision astronomical observations that refine astrophy... |

Stewart Sherrit, 2024, "A network model for piezoelectric flexure actuators", https://doi.org/10.48577/jpl.GWO9YG, SPIE Smart Structures and Nondestructive Evaluation 2024, JPL Open Repository
We investigate flexure piezoelectric stacks to produce large force and fine position control. The network model for the free ideal stack with many layers was first worked out by Martin [Martin 1963, 1964a, 1964b]. He noted that the stack impedance model in the limit of large laye... |

Spacecraft can carry microbial contaminants from spacecraft assembly facilities (SAFs) to the cold arid surface of Mars that may confound life detection missions or disrupt native ecosystems. Dry hygroscopic sulfate and (per)chlorate salts on Mars may absorb atmospheric humidity... |

Robert Hodyss, 2024, "Polar Opposites Attract on Saturn’s Moon Titan", https://doi.org/10.48577/jpl.OSFT1B, Science, JPL Open Repository
That polar and non-polar compounds do not spontaneously mix is a textbook rule of chemistry with few exceptions. Here we provide evidence for the intercalation of methane, ethane, and small hydrocarbons into the lattice structure of hydrogen cyanide (HCN), a highly polar molecule... |
