About cosine (Berlin Adlershof)

cosine is a space instrumentation company founded in 2001 and headquartered in Leiden, the Netherlands. The company designs, builds, and tests high-performance optical instruments and payloads for scientific and commercial satellite missions.

cosine specializes in hyperspectral imaging technology, developing compact optical payloads such as the HyperScout line of instruments used for Earth observation. These systems provide onboard hyperspectral image processing capabilities, enabling real-time data analysis directly on small satellites.

The company has supplied instruments and subsystems to ESA missions, national space agencies, and commercial small satellite operators. cosine's engineering team combines expertise in optics, mechanics, and electronics to deliver flight-qualified payloads for CubeSats and larger satellite platforms.

With a growing presence in the European New Space sector, cosine partners with satellite manufacturers and research institutions across Europe to advance the capabilities of miniaturized, high-performance Earth observation instruments.
