## EO-1 Technology Validation Overview

***EO-1 Technology Validation Overview***

***Instrument teams (MIT/LL, TRW, AC) will perform detailed instrument on-orbit calibration and performance verification during first 60 days on orbit***
***Detailed list of DCEs have been compiled and simulated in mission planning exercises***
***Major technologies are in instrument and will be validated via paired scene comparison with Landsat 7 or special scene requests by NRA-selected Science Validation Team (SVT)***
***SVT has provided first draft list of scenes to MSO***
***Other technologies (except EFF and PPT) are passive, requiring only trending data periodically to provide necessary validation data***
***PPT will not be tested until end of mission***
***EFF has detailed plan for moving from semi-auto to autonomous mode***
***XPAA will be utilized operationally, validated every 60 days***
***NRA proposals selection based on creation of a  Science Validation Team to ensure that instrument technologies are completely validated and can eventually meet future Landsat 8 science requirements***
***Metrics:  ***
***Instrument checkout reports by day 90***
***NRA Validation plans completed by end of mission (1 year)***

## Accelerated EO-1 Mission Testing

***Accelerated EO-1 Mission Testing***

***Per Bryant’s chart, goal is to Achieve Successful Mission criteria within 120 days after launch vs previous 1 year timeframe***
***Revised and integrated site list developed by MSO and ready for simulation (early Aug 11-19)***
*Site list prioritized*
*Allows for selection of up to 8 DCE’s per day based on cloud cover predictions*
***Mission planning and data processing simulations since April have attempted to exercise ability of EO-1 ground system to handle****** ******planning and level zero processing of up to 8 DCE’s per day***
***Additional disks on order for LZP system***
***Expect addition of one mission planner to allow weekend mission planning support***
***Expect augmentation to SVF to support additional DCE processing and required media***
***Expect augmentation to SVT to support Southern Hemisphere campaign***

## Additional Testing Since Last Red Team Review

***Additional Testing Since Last Red Team Review***

***WARP/Instrument Turn On Simulation in T/V II***
***48 hr simulation run on July 5-7, exercised timeline and procedures for activating XPAA,WARP, ALI, LAC and Hyperion and first images for all three instruments.***
***Minor procedural issues and violation of constraints discovered (images a bit too long for S-band passes, simultaneous WARP Rec/Playback attempted)***
***Nominal Operations Simulation in T/V II***
***Verified EO-1  end to end planning and data processing system***
***7 DCE’s (for a day), five X-band downlinks planned by MSO collected and imaged by S/C and processed by DPS***
***Minor issues discovered, mispointing of S/C due to image spanning the  international date line, and other minor scheduling issues***
***Mission Planning Simulation***
***Two Simulations held to test ability to image average of 8DCE’s per day.***
***May 4-11, July 10-14 (normal ops sim)  ***

## Other Validation Changes

***Other Validation Changes***

***ICD Status***
***As result of SVT meeting in early June, additional changes to MIT/LL provided calibration pipeline software, to support alignment and band co-registration ***
***MSO requesting changes in output product format for Hyperion Level One processing***
***Other Changes***
***Lunar calibration changed due to constraints and tested in T/V II***
***ALI long image ATS tested***
***Hyperion imaging (RTS’s) to use secondary lamp due to degradation of primary lamp***
***Continue to hold weekly telecons and monthly meetings to resolve mission planning and processing issues and refine overall system***

## Summary

***Summary***

***Validation requirements have not changed***
***EO-1 Planning and Processing system has been tested end to end and is fully operational***
***Minor refinements needed to support SVT needs***
***Minor augmentation to support accelerated mission requirements***
***System has been fully exercised and ready to support launch, instrument activation, and normal operations***
