This paper examines a complete (on board, on ground) Low Earth Orbit system solution to allow Ka-Band propagation measurements and Variable Coding and Modulation (VCM) demonstration through multiple ground stations. It provides a step towards the adoption of the 25.5 to 27GHz band for Earth Observation (EO) downlink from LEO. This paper contains key(More)
It has long been believed that molecular fluorine, F 2 , would not react with or etch Si. To overcome this problem, scientists used a plasma environment. Because the plasma dissociates the molecular F 2 or other fluorine containing molecules into F atoms, it was believed that these species are responsible for reacting with the Si surface to form the(More)
