Datum Systems designs, manufactures, and sells satellite and troposcatter modems through an OEM model, serving customers in more than 120 countries since 1986. Its devices are designed to be compact, efficient, and feature-rich, suitable as standalone ground stations or easily integrated into mobile ground, aero, man-pack, or maritime terminals, with a focus on SWaP. The satellite modems cover GEO, MEO, LEO, and HTS scenarios, delivering high efficiency and throughput in a small footprint, while troposcatter models are intended for outdoor terminals and radios with robust diversity for reliable links. Datum provides a broad set of interfaces and APIs to support integration into larger ecosystems and enable end-to-end customer solutions. The company is based in Mesa, Arizona, and operates as a small to mid-sized firm with a global reach. A notable recent development is a December 2025 partnership with Globecomm Systems.
