The ASTL is located at the NASA Ames University-Affiliated Research
Center, and is run in collaboration with the University of California
at Santa Cruz. It is engaged in enabling and performing airborne
measurements for the NASA science community. It has functions
for technology development, science support, sensor operations
and calibration, and is actively developing standard interfaces
and protocols for the cross-platform portability of NASA airborne
instrumentation.
The ASTL also operates several facility assets for the SSP, including standalone precision navigation systems (Applanix POV-AV IMU/DGPS units), Cirrus/DCS digital tracking cameras, and telemetry and aircraft navigation data interface hardware. This utility hardware is available for use by authorized SMD investigators. The lab also operates the MODIS and ASTER Airborne Simulators (MAS and MASTER) for the EOS program, which are made available to other NASA scientists by prior arrangement.
The Data Processing team provides sensor data reduction, analysis and mission support.
- Post-Flight Data Evaluation
- Processing, Archive and Distribution of Facility Sensor Data
- Level 1-B Data Production for MODIS & ASTER Airborne Simulators
- Mission Documentation & EOS DAAC Interface (GSFC,EDC)
- Flight Planning, Mission Coordination, and Investigator Liaison
The Sensor Operations team provides support for airborne sensor operations and remote deployments.
- Provide Maintenance and Engineering Support
- Payload preparation and Pre-Flight Check-Out
- Provide Onboard Operators, as Required
- Support System/Platform Integrations
The ASTL Calibration Laboratory is a community resource that is co-funded by the Suborbital Science and EOS programs. It performs NIST-traceable spectral and radiometric characterizations of remote sensing instruments. New capabilities added this year included a transfer radiometer for calibrating radiometric sources, and a high-temperature cavity blackbody. The lab also provides portable radiance sources (integrating spheres) and an ASD spectrometer to support field experiments.
The Sensor Calibration Laboratory Is Responsible for the Characterization of Earth-Viewing Sensor Systems In Support of EOS Investigations.
- Spectral Response Measurements (350nm-15um range)
- Radiometric calibration (Visible to Thermal Infrared)
- Spatial Characterization
- Environmental Simulation
- NIST Traceability
- Oversight by the EOS Calibration Scientist
