Space Environment Technologies

Space Environment Technologies (SET), founded in 2004 and headquartered in Pacific Palisades, California, is a commercial space weather services company providing real-time radiation environment measurements, space weather data products, and cloud-based analytics — specializing in the atmospheric radiation environment that affects aircraft crews, passengers, and avionics, and the near-Earth radiation environment affecting satellite operations.

SET's flagship program is ARMAS (Automated Radiation Measurements for Aerospace Safety) — an aviation radiation monitoring network that has accumulated over 1,100 commercial aviation flights equipped with compact radiation measurement instruments providing real-time dose rate data at flight altitudes. These instruments measure the galactic cosmic ray and solar energetic particle radiation field that penetrates aircraft fuselages, accumulating dose in human tissue and in avionics components.

ARMAS data enables quantification of crew and frequent-flyer radiation doses, supports ICAO (International Civil Aviation Organization) compliance with occupational dose limits for aircrew, and provides real-time input to radiation alert systems during solar energetic particle events that can suddenly elevate polar aviation doses to concerning levels.

SET acquired the SpaceWx trademark from Northrop Grumman, establishing the company's brand identity in the commercial space weather intelligence market. The company provides cloud-based data applications that ingest SET's own sensor data alongside public space weather data sources (NOAA, NASA, ESA SWARM) to deliver customized space weather intelligence products for aviation customers, satellite operators, power grid operators, and military space situational awareness programs.

SET competes with Metatech, Atmospheric and Environmental Research (AER), and SpaceWeather.com in the commercial space weather market, differentiating through the ARMAS real-time airborne measurement network that provides atmospheric radiation truth data unavailable from satellite-based or ground-based space weather monitoring networks alone.
