On-Orbit Performance Monitoring of Satellite Sensors
Research Guide
What is On-Orbit Performance Monitoring of Satellite Sensors?
On-Orbit Performance Monitoring of Satellite Sensors tracks sensor degradation and calibration using onboard lamps, solar diffusers, and pseudoinvariant sites for instruments like VIIRS, OLI, and MODIS.
Researchers analyze detector response changes over time for sensors on satellites such as Suomi NPP and Landsat-8. Methods include vicarious calibration and spectral response monitoring post-launch. Over 10 key papers document performance of VIIRS (Cao et al., 2013, 510 citations), TIRS (Barsi et al., 2014, 423 citations), and OLI (Barsi et al., 2014, 375 citations).
Why It Matters
On-orbit monitoring ensures long-term data accuracy for climate records from MODIS (Levy et al., 2013, 2341 citations) and VIIRS (Cao et al., 2013). Vicarious calibration of Landsat-8 TIRS maintains thermal imaging continuity (Barsi et al., 2014). RXTE PCA performance tracking enabled X-ray timing studies over decades (Jahoda et al., 1996). Degradation modeling predicts end-of-life sensor accuracy for missions like Herschel PACS (Poglitsch et al., 2010).
Key Research Challenges
Sensor Degradation Modeling
Modeling non-linear detector response changes from radiation and thermal effects challenges accuracy predictions. VIIRS early performance showed scan-to-scan variations (Cao et al., 2013). MODIS collections required updated algorithms for aerosol retrieval stability (Levy et al., 2013).
Onboard Calibrator Stability
Onboard lamps and solar diffusers degrade, complicating reference measurements. Landsat-8 TIRS vicarious calibration addressed stray light issues (Barsi et al., 2014). PACS photoconductor arrays needed stressed/unstressed monitoring (Poglitsch et al., 2010).
Pseudoinvariant Site Variability
Atmospheric and surface changes at calibration sites introduce noise in trend analysis. MODIS dark-target products evaluated land site consistency (Levy et al., 2010). OLI spectral response calibration used pre- and post-launch site data (Barsi et al., 2014).
