Laser-Guide-Star Satellite for Ground-Based Adaptive Optics Imaging of Geosynchronous Satellites
Marlow, Weston; Carlton, Ashley; Hyosang, Yoon; Clark, James; Haughwout, Christian; e.a. (Journal of Spacecraft & Rockets, 2017-05)In this study, the feasibility and utility of using a maneuverable nanosatellite laser guide star from a geostationary equatorial orbit have been assessed to enable ground-based, adaptive optics imaging of geosynchronous ... -
Response of geostationary communications satellite solid-state power amplifiers to high-energy electron fluence
Lohmeyer, Whitney; Carlton, Ashley; Wong, Frankie; Bodeau, Michael; Kennedy, Andrew; e.a. (AGU Space Weather, 2015-05-25)The key components in communications satellite payloads are the high-power amplifiers that amplify the received signal so that it can be accurately transmitted to the intended end user. In this study, we examine 26 amplifier ... -

Telemetry Fault-Detection Algorithms: Applications for Spacecraft Monitoring and Space Environment Sensing
Carlton, Ashley; Morgan, Rachel; Lohmeyer, Whitney; Cahoy, Kerri (2018-05-19)Algorithms have been developed that identify unusual behavior in satellite health telemetry. Telemetry from solid-state power amplifiers and amplifier thermistors from 32 geostationary Earth orbit communications satellites ... -
Using the Galileo Solid-State Imaging Instrument as a Sensor of Jovian Energetic Electrons
Carlton, Ashley; de Soria-Santacruz Pich, Maria; Kim, Wousik; Jun, Insoo; Cahoy, Kerri (2018-04-16)We quantitatively describe the Jovian energetic electron environment using the Solid State Imager (SSI) on the Galileo spacecraft. We post-process raw SSI images by removing the target object and dark current to obtain ...
