GOES-17 Advanced Baseline Imager (ABI) Performance Comparison to GOES-16

The 17^th Geostationary Operational Environmental Satellite (GOES-17) was launched March 1, 2018. The Advanced Baseline Imager (ABI) is the primary instrument on the GOES-R series for weather and environmental monitoring. With three times the spectral bands, four times the spatial resolution, and five times the image collection rate, ABI significantly improves the quality and frequency of existing data products and provides many new weather and environmental products.

The GOES-16 ABI (flight model 1), currently active as GOES-East, has already demonstrated these improvements during on-orbit operations. This presentation provides preliminary post-launch test results for the GOES-17 ABI (flight model 2), compares GOES-17 ABI performance with the operational performance of GOES-16 ABI, and demonstrates the build-to-build consistency of the ABI. Quantitative performance results for SNR and NEdT, line-of-sight stability, navigation, registration, and calibration stability will be presented. Any significant differences will be discussed.
