# OSK SIGMA
*analysis-service . products*

Commercial hyperspectral analytics platform operated by Orbital Sidekick (OSK), San Francisco. SIGMA (Spectral Intelligence Global Monitoring Application) delivers analyst access to the GHOSt (Global Hyperspectral Observation Satellite) constellation: tasked acquisition, archive search, automated change-detection alerts, and spectral analytics outputs. GHOSt covers 400-2500 nm VIS-SWIR in 512 contiguous bands (per eoPortal; Gunter Space Page hedges this as 400-plus) at approximately 8 m GSD from a 525 km sun-synchronous orbit. Primary customer verticals are mining and mineral exploration (SWIR alteration mineral mapping, target generation), energy infrastructure monitoring (pipeline corrosion, hydrocarbon seep detection, emissions), and defence and intelligence customers. In-Q-Tel backed. Founded 2016. Structurally comparable to a commercial analytics subscription service rather than an open-data portal: access requires a commercial contract covering tasking, archive, and processed output.
