Comm Link Analysis
Spacecraft are getting smaller, making the job of maintaining data volume and integrity a challenge. SDL simulates the spacecraft environment to verify the design prior to testing and then uses the data to improve the overall system performance and minimize risk during assembly, test, and flight. This ensures that the high volume of valuable data collected on orbit is all transmitted to the ground successfully. These simulations identify how much data can be transmitted to the ground within each pass and determine ground contact frequency and duration for one or multiple ground sites.
- Orbital analysis of spacecraft to ground station overpass characteristics
- Link analysis of multiple spacecraft (constellations) and ground stations
- Analysis for range velocity, Doppler, path losses, and encoding schemes
- Modeling and simulation of ionospheric effects on communication signals
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.
Hyper-Angular Rainbow Polarimeter
The HARP instrument is a wide field-of-view hyper-angular imaging polarimeter designed to characterize aerosol and cloud properties.
