Laser-Guide-Star Satellite for Ground-Based Adaptive Optics Imaging of Geosynchronous Satellites
(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 ...
Using the Galileo Solid-State Imaging Instrument as a Sensor of Jovian Energetic Electrons
(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 ...
Telemetry Fault-Detection Algorithms: Applications for Spacecraft Monitoring and Space Environment Sensing
(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 ...
Response of geostationary communications satellite solid-state power amplifiers to high-energy electron fluence.
(American Geophysical Union, 2015-05)
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 ...
