Environmental Modeling & Instrument Response

To correctly design and operate space-based instrumentation, a clear understanding of the expected environment and the instrument response to the environment must be obtained. SDL provides modeling of RF signal propagation and phased arrays through the ionosphere RF signal processing for remote sensors for ionospheric structures.


  • Specification of expected environment using climatological, empirical, and physics-based models
  • Probe interactions with the local environment
  • Environmental interactions and interference with RF and optical remote signals
  • Antenna and phased array antenna systems



Dynamic Ionosphere Cubesat Experiment

Twin CubeSats mapped the geomagnetic Storm Enhanced Density (SED) plasma bulge and plume formations in Earth’s ionosphere.


Auroral Spatial Structures Probe

ASSP was designed to measure the spatial and temporal variation of the energy flow in the upper atmosphere in and around the aurora to better understand global temperature changes in the thermosphere.


Floating Potential Measurement Unit

The FPMU is an important diagnostic tool that helps enable NASA to monitor and control surface charging on the International Space Station, reducing risks to astronauts during extra-vehicular activity.


Oxygen Photometry of the Atmospheric Limb

The OPAL 3U CubeSat mission is designed to provide accurate and reliable space environment specifications to assist in the effort to mitigate the adverse effects of space weather.
