PRECISION CALIBRATION, ACCURATE DATA

• Verification and validation of science data systems and products
• Vicarious calibration and validation
• Instrument characterization and modeling
• Instrument algorithm and software development
• Laboratory and field support

Carefully calibrated instruments are crucial to mission success. To meet this need, Sigma Space offers its clients a diverse array of verification and validation services, such as

• Performing radiometric calibration of instruments and illumination sources
• Maintaining laboratory equipment to established NIST standards
• Providing vicarious instrument calibration through detailed modeling of spatial and radiometric instrument responses over time
• Collaborating with operational systems and science teams to develop calibration tools—and monitor and diagnose instrument performance while on orbit

These capabilities are exemplified in our many verification and validation activities, including

• Ongoing support and improvement of NASA GSFC calibration labs
• Prelaunch support of the NPP VIIRS and the LDCM OLI and TIRS instruments
• Support of operations for EO-1, Landsat, MODIS, and VIIRS

As demonstrated by Sigma Space’s success on current and past projects, our verification and validation staff have the expertise to ensure that customer data systems and instruments function optimally—returning reliable, high-quality data.
