For 22 years (from ATS-1 to GOES-H) a single technology has dominated imaging from geosynchronous altitudes. In 1990, with the scheduled launch of GOES-I, a major change will occur which will in turn open the way for the Geostationary Platform. The need for improved observations of severe storms has led NOAA to a decision to replace spinning geostationary spacecraft with a three-axis-stabilized type (non-spinning) vehicle already common among communications spacecraft and demonstrated by INSAT. Also, the current spin-scan imager with sounder channels will be replaced by separate instruments capable of independent aiming. The advantages and challenges of the changes are discussed.
