What is Satellite Sensor Calibration?
Satellite Sensor Calibration ensures the accuracy of satellite imaging sensors through on-orbit adjustments using vicarious methods, star observations, and permanent radiometric sites to preserve geometric and radiometric fidelity.
This subtopic covers pre-launch spectral characterization and on-orbit validation for sensors like Landsat-8 OLI and ALOS PRISM (Barsi et al., 2014; Tadono et al., 2014). Researchers model temporal degradation and develop cross-calibration protocols for multi-sensor data consistency. Over 20 key papers from 2013-2022 address these techniques, with Tadono et al. (2014) cited 640 times.
Why It Matters
Precise calibration maintains data quality for multi-decadal environmental monitoring, enabling quantitative analysis in climate studies and land cover mapping (Barsi et al., 2014). It supports global DEM generation from ALOS PRISM, aiding geospatial applications like disaster response (Tadono et al., 2014). Accurate radiometric fidelity from OLI spectral response calibration ensures reliable vegetation indices and surface reflectance products (Barsi et al., 2014).
Key Research Challenges
On-Orbit Degradation Modeling
Sensors degrade over time due to radiation exposure, requiring models to track radiometric changes. Vicarious calibration using ground sites addresses this but faces atmospheric variability (Barsi et al., 2014). Tadono et al. (2014) highlight maintaining PRISM accuracy across global datasets.
Cross-Sensor Calibration Protocols
Aligning spectral responses across missions like Landsat-8 and ALOS PRISM demands standardized protocols. Inter-sensor misregistration impacts multi-temporal analysis (Scheffler et al., 2017). Barsi et al. (2014) relate pre-launch data to on-orbit artifacts.
Geometric Fidelity Maintenance
Stereo mapping sensors like PRISM require precise calibration for DEM accuracy. Orbital dynamics and attitude errors complicate on-orbit adjustments (Takaku et al., 2014). Tadono et al. (2016) discuss 30m global DSM generation challenges.
