System Calibration Planning
Calibration planning should begin early during the instrument design phase to ensure the design can accommodate the measurement methods of an efficient calibration approach. SDL’s calibration planning includes gathering and filtering information, performing analyses and trade-off studies, and creating test plans that maximize the sensor performance information obtained within the budget and schedule constraints of the program.
- Pre- and post-launch calibration planning
- Optimum calibration approach determined by performing trade-off of cost, schedule, uncertainty, equipment, and risk
- Instrument requirements that are flowed to calibration requirements and then to calibration measurements
- Efficient and streamlined calibration test schedule and data collection
- Trade-offs between component vs. system-level testing
- Sensor performance/radiometric modeling
- Identification of calibration parameters and equations
- Environmental conditions for calibration testing
- Identification of calibration sources and other support equipment
- Comprehensive calibration plans and data collection procedures
- Data collection and data management systems planning
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.
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.
Far-Infrared Spectroscopy of the Troposphere
FIRST is a long–wave imaging spectrometer that measures between 10–100 µm, filling a gap in the existing systems that monitored the Earth’s climate.
Space Based Infrared System
SBIRS High is a two-tier remote sensing satellite system working with other US defense systems to provide global below- and above-the-horizon detection as well as tracking and discrimination of missiles in their boost, post-boost, midcourse and reentry phases of flight.
