Study multi-frequency radio wave interference produced by the atmosphere at sunset near the equator.
Study the multi-frequency radio wave interference produced by the atmosphere at sunset near the equator. The spacecraft will receive multiple broadcast digital television channels to probe the ionospheric irregularities. Exploring the 3D structure of scintillation-scale irregularities of DTV signals in the ionosphere associated with Equatorial Spread F. The experiment will compare ground-to-space UHF scintillation measurements taken at multiple points along a flux tube. The payload on ISX is developed by SRI. There are 27 viable passes over a year. Passes will last no longer than 2.5 minutes.
|Failure cause||In depth failure mode analysis performed, but failure cause not identified.|
