Instrument Engineering integrates components into complex systems that accomplish tasks. For our customers, SSAI provides instrument engineering for systems critical to successful research in Earth and Space Science, such as sensors that must operate reliably in harsh environments. We support instrument and system design, define component specifications, and oversee the installation and calibration of these systems.

SSAI provided extensive instrument engineering for the Wilkinson Microwave Anisotropy Probe (WMAP), giving researchers unprecedented precision in describing the universe’s origin. SSAI instrument engineers analyzed all elements of sensor systems’ performance, including signal-to-noise analysis, thermal effects on radiometers, and effectiveness of varying antenna patterns. With this information, we helped to engineer WMAP’s systems, which are among the most accurate available.

NOAA's Deep Space Climate Observatory (DSCOVR) is designed to monitor solar activity, reporting on solar activity and warning of space weather activity that could affect Earth. SSAI Engineers have worked closely with the DSCOVR team, developing simulations that test the accuracy and reliability of the spacecraft and instruments. SSAI helped integrate the instruments with the spacecraft and test instrument electronics to ensure they function properly in the spacecraft’s orbit, a million miles away from Earth.
