Abstract

During 1997-98, the NASA-NOAA Advanced Geosynchronous Studies (AGS) program sponsored work to explore the possibility of designing a high-quality imaging radiometer for the future GOES platforms. The AGS Imager (AGSI) design calls for the acquisition of 12-bit digital images every few minutes in 18 spectral bands with horizontal resolutions ranging from 0.3 to 1.5 km on a full-earth disk. The resulting raw sensor data stream is approximately 300 Mbits/sec, uncompressed. The AGSI ground system must convert the sensor data into calibrated, earth-located 'Level 1b' images and deliver them to NOAA and to the science community within minutes of reception. To accomplish this high-speed digital-image delivery, the AGSI downlink design calls for lossless compression to 150 Mbits/sec, packetized using CCSDS standards with error-correction, and broadcast in Ka- band to a low-precipitation site like White Sands, NM.
