The main functionality included in this release is to ingest a simulated GRB data stream, recover Advanced Baseline Imager (ABI) Level 1 and Geostationary Lightning Mapper (GLM) Level 2 data payloads, reconstruct the datasets, and write output to mission-standard NetCDF files. Optionally, quicklook images can be generated from the ABI radiances. Later releases will add support for recovering data from the remaining GOES-R instruments: SUVI, EXIS, MAG and SEISS. This software is supported on 64-bit Centos6-compatible Linux platforms.

19. CGMS-43-NOAA-WP-10 Coordination Group for Meteorological Satellites - CGMS Details of the GRB Dual Polarized Signal Slide: 19 Reception of the GRB data requires a fixed dish antenna Dual feed horns connected to 2 Low Noise Amplifiers (LNAs) The LNA outputs are connected to RF/IF down-converters RF/IF down-converters connected to DVB-S2 capable receivers The GRB downlink center frequency of 1686.600 MHz requires an antenna G/T of 15.2 dB/K for worst-case locations. This equates to a 4.5 meter dish with a system noise temperature of 120K. Most CONUS locations are anticipated to have acceptable performance with a 3.8 meter dish. You will need a new receive system from antenna to computer.
