Aerojet's current Advanced Microwave Sounding Unit (AMSU) orbits the earth, passively measuring the intensity of particular microwave frequencies for meteorological purposes. The team has explored and analyzed a number of new and innovative technologies in an effort to reduce the size and manufacturing cost of the AMSU receiver subsystem. Extensive research was done to determine the fundamental properties of the different technologies in order to pinpoint their limitations and foresee possible advances. The team has proposed feasible alternatives to the design of the current AMSU.
