The Automated Radiation Measurements for Aerospace Safety (ARMAS) program has been developed with NASA funding. It provides accurate, real-time radiation monitoring along with radiation and space weather awareness for the global airspace up to 100 km altitude. The ARMAS app is part of this program and does two tasks: - it pairs with and controls the 7th generation ARMAS Flight Module (FM7) and the 12th generation ARMAS Flight Module (FM12) radiation detector (purchased separately) to provide the highest quality, real-time dose and dose rates in aircraft and suborbital vehicles. It is sensitive to radiation from all sources including heavy ions, alphas, protons, neutrons, electrons, and gamma-rays. - it provides radiation awareness by hosting real-time space weather data coming from dozens of ground- and space-based systems that report all the information relevant to radiation processes without requiring a purchase of the FM7 or FM12. ARMAS is the 'gold-standard' in real-time radiation monitoring and awareness used by professional pilots, business travelers, and commercial space tourists. The ARMAS program is developed and operated by Space Environment Technologies, which specializes in space weather as an official NOAA "Weather Ready Nation" Ambassador.
