Modeling & Simulation

Modeling and simulation enables engineers to gain an in-depth level of understanding of how the parts in a system interact and the system as a whole. SDL’s engineers use cost-effective simulation tools to ensure all performance metrics are met and provide confident design solutions.


  • Sensor performance simulation tools for cost-effective development
  • Modal and dynamic response analysis
  • Structural and thermal analysis
  • Control system performance simulation
  • UV EO/IR sensor radiometric modeling and analysis
  • In situ environment and RF remote sensing payloads
  • Optical analysis



Real-time, Autonomous, Synthetic Aperture Radar

RASAR is a full-featured, flight-proven, 25-lb radar system with expandable capabilities that include dual-band operation, ground moving target indicator (GMTI), and comprehensive data processing and image formation capabilities.


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.


Wide-field Infrared Survey Explorer

The WISE cryogenically-cooled infrared telescope provided a complete stellar infrared map more than 1,000 times more detailed than previous surveys.


Geosynchronous Imaging Fourier Transform Spectrometer

GIFTS was successfully tested and calibrated as an engineering demonstration unit to ground-validate technologies critical to NOAA’s Hyperspectral Environmental Suite for the Geostationary Operational Environmental Satellite (GOES) system.


Aeronomy of Ice in the Mesosphere Solar Occultation for Ice Experiment

SOFIE is one of three instruments aboard the Aeronomy of Ice in the Mesosphere (AIM) satellite. AIM’s objective is to study polar mesospheric clouds and the environment in which they form.


Sounding of the Atmosphere using Broadband Emission Radiometry

SABER, a 10-channel infrared (1.27 to 16.9 µm) radiometer, is one of four instruments on NASA's TIMED mission, which is dedicated to study the dynamics of the Mesosphere and Lower Thermosphere (MLT) portion of the Earth's atmosphere.


Spatial Infrared Imaging Telescope

SPIRIT III was the infrared sensor aboard MDA’s Midcourse Space Experiment (MSX). This long-wave infrared instrumentation package consisted of a high spatial resolution radiometer, a high spectral resolution interferometer-spectrometer, and an extremely high-off-axis-rejection telescope.
