Thermal Modeling & Analysis

Thermal modeling and analysis simulations provide analytical verification of thermal designs prior to article fabrication and test, as well as model correlation to thermal test results for predictions in non-tested thermal conditions. SDL has decades of experience and expertise in thermal modeling and analysis ranging from cryogenic to ambient temperature regimes and terrestrial to on-orbit environmental conditions.

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.


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.


Ionospheric Connection Explorer

NASA’s Ionospheric Connection Explorer (ICON) mission will explore how both terrestrial and space weather affect conditions in the ionosphere.


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.


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.


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.
