Orbital Sidekick Global Hyperspectral Observation Satellite (GHOSt) payload: calibration and characterization
18 August 2024 • 4:20 PM - 4:40 PM PDT
Abstract
Hyperspectral imaging and its derived products are an in-demand, robust, and a highly informative source for a growing number of commercial and government applications. A higher quality and consistency of data products are essential to maximize the information delivered by applied analytics and machine learning techniques. A consistent data product also allows our GHOSt constellation to achieve signature stability over time and across different sensor payloads and sensitivities. This presentation provides an overview of Orbital Sidekick’s launched GHOSt constellation hyperspectral payload and of the calibration and characterization of these sensor(s) in orbit. These methodologies and results include discussion of RadCalNet spectral and radiometric calibration; as well as an overview of the GHOSt optical, image stability, and signal-to-noise characterizations.
