The Office of System Architecture and Advanced Planning (OSAAP), under National Environmental Satellite, Data, and Information Service (NESDIS) of National Oceanic and Atmospheric Administration (NOAA), conducted an architecture study working with MIT Lincoln Laboratory (MIT LL), the Aerospace Corporation, the Johns Hopkins University Applied Physics Laboratory (APL), the Goddard Space Flight Center (GSFC), and the Jet Propulsion Laboratory (JPL). Observations from NOAA’s operational environmental satellites provide critical inputs to weather and space weather forecasts on time scales spanning minutes to over a week. The goal of the study was to develop architectural constellations for all of NESDIS’s weather satellites in the 2030 timeframe, and then assess these architectural constellations for value and cost. High level instrument concepts were solicited from industry, as well as provided by JPL, MIT LL, and GSFC. An Environmental Value Model (EVM) of observational objectives, which contained observational parameter trade space values and satisfaction weighting defined by the Space Platform Requirements Working Group (SPRWG), was employed by MIT LL in systematically evaluating the value of the architectures. Inputs for architecture concepts and the methodology for evaluation of the approximately one hundred architectural constellations developed iteratively though the study will be discussed. The value versus costs curve, where architecture costs were supplied by APL, will be discussed for the architecture cycles. Error analysis associated with the evaluation process will be discussed as well.
