Earth Observing System (EOS) Advanced Microwave Sounding Unit-A (AMSU-A) Spares Program Plan

This plan specifies the spare components to be provided for the EOS/AMSU-A instrument and the general spares philosophy for their procurement. It also address key components not recommended for spares, as well as the schedule and method for obtaining the spares. The selected spares list was generated based on component criticality, reliability, repairability, and availability. An alternative spares list is also proposed based on more stringent fiscal constraints.

Earth Observing System (EOS)/Advanced Microwave Sounding Unit-A (AMSU-A) worst-case analysis: Antenna beam pointing

This report presents a worst-case analysis of the EOS/AMSU-A (Earth Observing System/Advanced Microwave Sounding Unit-A) Antenna beam-pointing accuracy. There are three sources of beam pointing error. These are mechanical tolerances in the manufacture and assembly of the parts, allowable axial displacement of the reflector relative to the motor shaft, and on-orbit thermal distortions. For the worst-case analysis, each will be assumed to act independently and thus each contribution is additive.
