Scientific paper

The emergence of reliable, miniaturized spacecraft technology has enabled the use of constellations of small spacecraft to achieve global observations of the atmosphere and geospace environment. The need for the spacecraft to be spread globally can be met even with a single launch vehicle by deploying the spacecraft in orbits with slightly different precession rates. Within one year, the spacecraft can be in orbits spread uniformly around the Earth. As many as ten to one hundred satellites can be launched from a single, commonly used launch vehicle, depending on their mass and volume. In this talk we describe the concepts behind achieving global coverage through a constellation of small spacecraft. We describe a small rugged solar occultation instrument that is well suited to this approach and is capable of obtaining high vertical resolution observations of a variety of species important to atmospheric and geospace research. Specific applications regarding stratosphere troposphere exchange are also discussed.
