Abstract

Infrared satellite links are examined to measure earth surface temperatures. The low earth orbits would offer low cost and Brandon orbits would offer the convenience of stationary ground antennas. A square array of ground stations is considered (‘Quad Diversity’) to relieve laser attenuation, and higher order diversity is considered. Jalali’s ten micron silicon laser links are studied for high reliability, terrestrial temperature measurements, and low cloud attenuation for clean terrestrial power. Even lower attenuation is found for satellite-aircraft links.
