cosine Research BV
Dutch optical instrumentation company (founded 1998, Sassenheim NL). Manufactures compact hyperspectral and X-ray optical systems for space and industrial applications. EO product line: HyperScout family (HS1/HS2/M/S), TScout, Valk. Three legal entities: cosine Research BV (NL parent), cosine GmbH (DE), cosine Remote Sensing SRL (IT).
cosine Research BV is a Dutch optical instrumentation company founded in 1998 and headquartered in Sassenheim, the Netherlands.[^cosine-news-ams] (Some secondary sources give the headquarters as Leiden or Warmond; the cosine.eu contact page lists postal address 2171 AH, which is Sassenheim municipality.[^cosine-contact]) The company develops mission-specific measurement systems across three domains: Remote Sensing, High-Energy Optics, and Inspection Systems. It sells payloads and systems to space agencies, satellite operators, and industrial customers, operating as a B2B instrument manufacturer rather than a satellite operator.[^cosine-contact]
The company's EO instrument heritage centres on the HyperScout family: compact hyperspectral imagers designed for CubeSat and small satellite integration. HyperScout 1, developed under ESA GSTP with a consortium including VITO, S&T, TU Delft, and VDL, flew on ESA's GomX-4B in 2018 at 500 km altitude, delivering 45-band VNIR imagery at 70 m GSD with real-time onboard processing.[^eoportal-gomx4] HyperScout 2, a dual-channel VNIR+TIR successor, flew on PhiSat-1 in 2020, adding a thermal infrared channel (8-14 um, 4 bands) and an AI inference capability for onboard cloud detection.[^eoportal-phisat1] eoPortal reports HyperScout 2 VNIR spectral resolution as 12 nm; academic literature gives 16 nm, and both figures remain in circulation with the discrepancy unresolved.[^eoportal-phisat1] Secondary sources claim ESA cross-calibration certification with Sentinel-2 for HyperScout 2; eoPortal and reachable ESA sources describe a planned cross-calibration strategy rather than completed certification, and the relevant ESA Phi-Lab page was unavailable as of 2026-05-23.[^eoportal-phisat1] A modified HyperScout 2 variant was also integrated into the Kanyini satellite for South Australia's space programme. HyperScout M, the most compact variant, launched in March 2024 as part of Thales Alenia Space IMAGIN-e external ISS payload and became operational in February 2026, producing Analysis Ready Data in orbit.[^cosine-news-imagin]
cosine High-Energy Optics division manufactures Silicon Pore Optics mirror modules for ESA NewAthena X-ray telescope, produced at a dedicated ISO Class 6 cleanroom at the BESSY II synchrotron facility in Berlin.[^cosine-news-berlin] A newer product, Valk, is a Very High Resolution EO sensor in development for Dutch Defence PANI-1 satellite, targeting ISR applications.[^cosine-news-4s]
The company operates through three legal entities: cosine Research BV (Dutch parent, Sassenheim), cosine GmbH (Berlin), and cosine Remote Sensing SRL (Benevento, Italy).[^cosine-contact]
