Sigma's science personnel perform a broad spectrum of Space and Earth sciences research and analysis activities. We process and analyze data from numerous ground, aircraft, and satellite instruments in delivering high quality science results. We are a firm believer in partnerships with our customers and work collegially in support of:

• Concept Development and Literature Reviews
• Hypothesis Development and Verification
• Proposal Development and Support
• Research planning and execution
• Empirical and Theoretical Modeling
• Data processing, analysis, and visualization
• Algorithm development
• Remote sensing applications
• Publications, presentations, and peer reviews

Properly designed, built, and maintained instrumentation is critical to testing current theories and expanding scientific knowledge and security capabilities. Sigma's instrument engineers, scientists, and technicians deliver outstanding instrument engineering services including:

• Science Requirements Analysis
• Requirements Translation and Flowdown
• Instrument Design and Engineering
• Reference Calibration and Maintenance
• Mission Planning and Operations

Today's research and scientific discovery efforts increasingly require very consistent and detailed data from a given sensor over time and/or the merger/fusion of data from multiple instruments at multiple instances in time. Sigma's staff has the experience to perform:

• 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

Increases in computer technology and capabilities have enabled much more thorough, insightful, and expansive collection, access to, and analysis of data. Advances in the reliability of hardware and software have allowed 24 x 7 operations to occur with minimal human oversight. Our highly skilled personnel provide computer systems support in the areas of:

• Scientific Computing (Algorithm and Application development)
• Data Visualization
• Operational Computing (System Development and Operations)
• Data Archiving
• Configuration Management
• Database Design and Maintenance
