Abstract

Instruments on the next generation operational GOES will generate an expected 50 times greater amount of data than their predecessors on today’s GOES. Part of this increase is due to the high-spectral resolution data from the Hyperspectral Environmental Suite (HES). The data increase led to the need to research the impact to the GOES satellite’s end-to-end communication system, and research compression of hyper-spectral sounder sensor data. The compression research, in mathematics includes, but is not limited to, wavelets, principal components, adaptive clustering, empirical mode decomposition. The high data rates require additional RF spectrum, in the congested 8025-8400 MHz band X-band. Congestion in the geo orbit X and L-bands mandate extensive efforts to control out-of-band RF emissions. The need for communication signal data quality with few errors (low BER) is essential for NOAA science use. Limited bandwidth and the need to be efficient in bandwidth use, force the consideration of bandwidth efficient modulations. These communication issues force the use of the latest technologies. The research has shown that GOES will be able to downlink all of the future sensor data, and could continue to be used as a communication satellite to distribute large volumes of its sensor information to U.S. and foreign users.
