Corning Incorporated has leveraged its industry leading space based hyperspectral technology to create an advanced Low Earth Orbit (LEO) Satellite Payload. We outline the specifications, performance, and capabilities of this new standard in LEO Hyperspectral Imaging (HSI). Corning’s new product platform is capable of ⪅8m GSD imaging across the 400nm-2500nm spectral band with high dispersion. It has onboard computing, storage, and processing capabilities which enhance its exceptional optical and sensor performance. Corning’s design exceeds the launch stress requirements of standard LEO Transporter vehicles, such as the SpaceX Falcon-9, and has been proven on multiple successful LEO missions. The product platform contains a flexible electro-mechanical interface design suitable for a variety of host bus platforms and functions.
Commercial Hyperspectral Imaging (HSI) systems capable of both fine spatial ground resolution and high signal to noise ratio pose challenges to the integration and testing process. The following will describe methods developed for a Low Earth Orbit (LEO) system having an effective focal length of approximately one meter and a ~f/2 optical speed. Internal subsystem testing is outlined as it relates to full-system performance. A sub-aperture testing routine is described to establish baseline performance estimates for spatial and spectral characteristics at a system level. Analysis and testing results are presented as measured during the integration process.
