Goddard Space Flight Center GOES-R FLIGHT PROJECT OFFICE Terminology • Prototype Model (PTM) – – Not a flight instrument Pathfinder to demonstrate ABI design and test program Qualification model for ABI design and test program Built, integrated, and in the midst of instrument-level testing • Protoflight Model (PFM) – First flight instrument – Will be tested at protoflight levels – Many components and some assemblies are in production • Ground Processing Development System (GPDS) – Implementation of all ABI ground processing algorithms on real hardware run in real time proving latency requirements are met – Same software used to process PTM data 2 NASA and NOAA Internal Use Only 12/1/2020 2

Goddard Space Flight Center GOES-R FLIGHT PROJECT OFFICE Executive Summary: ABI Meeting Mission Requirements • ABI is a significant advancement over current Imager • System design proven robust – System architecture has not changed since PDR – Completed PTM subsystem testing – Bench test ongoing • PTM (pathfinder) is doing its job – Risks mitigated early to ensure successful flight program 3 NASA and NOAA Internal Use Only 12/1/2020 3

Goddard Space Flight Center GOES-R FLIGHT PROJECT OFFICE ABI vs. GOES-N Imager: 48 x Increase in Information Plus Operational Flexibility • Temporal: 6 x – Full Earth disk: 5 minute vs. 30 minutes – 15 minutes: 1 full Earth disk + 3 CONUS + 30 mesoscales • Spectral: 3 x – 16 channels (0. 47 -13. 3 µm) vs. 5 channels (0. 64 - 13. 3 µm) • Spatial: 2 x – 0. 64 µm channel = 14 µrad (0. 5 km) vs. 28 µrad (1 km) – 0. 47, 0. 86, and 1. 61 µm channels = 28 µrad (1 km) – Other channels = 56 µrad (2 km) vs. 116 µrad (4 km) • 24/7 Operations – Operation through eclipse and within 3° of sun • Data rate: 26 x – < 66. 6 Mbps compressed vs. 2. 6 Mbps uncompressed 5 5 NASA and NOAA Internal Use Only 12/1/2020 5

Goddard Space Flight Center GOES-R FLIGHT PROJECT OFFICE Strengths of ITT’s ABI • Scans parallel to equator with no image plane rotation – Greatly simplifies ground processing • Doesn’t require a yaw flip – But can operate in yaw flipped configuration by setting a single bit – ground commanding need not change • Scan patterns and rates fully configurable on orbit – New scenes and timelines can be uploaded post launch • Optimized system delivers no gaps with little overlap (1%) • INR performance delivered for all images, not just full disk • Rapid slews generate little spacecraft disturbance – Optimized slew profiles 6 6 NASA and NOAA Internal Use Only 12/1/2020 6
