## Landsat Mission Background

***Landsat program has continually acquired synoptic images of the Earth’s land surfaces for almost 30 years.***
***At least one Landsat satellite has been acquiring data since the 1972 launch of Landsat 1***
***Landsats 5 & 7 are extending a 30 year record of the land surface***
***Landsat has evolved to a global survey mission***
***Affording synoptic coverage of the Earth’s land mass on a seasonal basis***
***Providing multispectral digital image data with a moderate spatial resolution (~ 30 meters) for:***
*Assessment of land cover and land use change over time*
*Characterization of land ecosystem processes*
*Management of land resources*
***Serving Government (Federal, state, local, and foreign) as the largest customer, directly or indirectly, of Landsat data***

**Notes:**
Partner—USGS;  Introduce Ray

Recognize participants—Industry, Science, Congressional Staff

Introduce presenters—Proj Scientist, Lead Systems Eng., Contracting Officer, HQ Program Executive

## Procurement Approach

***In an effort to move towards a private sector supplier of Landsat-like data, LDCM has been framed around a ***_***data specification***_*** with data delivery starting March 2006.***
***Gov’t specifies spectral, spatial and radiometric qualities of data.***
***Maximizing Industry’s flexibility in systems for data acquisition***
***Defining the data as the ***_***principal***_*** deliverable,***
***Desiring to share cost, risk, and rewards, and***
***Making available relevant new technologies, such  as EO-1 sensor(s), to data  providers.***
***Step 1 is Formulation (Phase A/B) with multiple contractors.***
***Step 1 RFP released November, Awarded late March 2002***
***DigitalGlobe and Resource21 selected as Formulation Phase Contractors.***
*Trade studies results by Aug 02’ *
*System PDR in Nov 02’*
***Step 2 is Implementation with a single contractor (Phase C/D/E).***
*** ******Step 2 RFP release expected circa December, 2002, Award in May/June 03’***
*** ******Data Delivery begins March 2006***
***The data provider may use ***_***any reasonable means***_*** of producing the data, but the ******Government must validate:***
***The approach, (business case included)***
***The implementation, and ***
***The data. ***
***The Government may provide milestone payments during system development for demonstrated progress.****** ***

## LDCM-EO1 Technology Infusion

***Candidate EO-1 Technology and “experiences” being infused into LDCM***
***Advanced Land Imager (ALI)***
*WFOV, pushbroom scanner,*
*Focal plane (large number of detectors)*
*Pre and Post validate calibration/characterization and validation*
*On-board calibration (lunar, solar, stellar)*
*Data Processing (L0,L1R)*
***WARP ***
*High rate data recording, data management, error correction, high rate downlink capabilities.*
***RF (XPAA)***
*Ability to work with diverse ground station.*
*High data rates*

## Intangible Benefits to LDCM from EO-1

***EO-1 In-tangible payoff***
***Science Validation Team – expert and broader user community have gained extensive experience in utilizing EO-1 data, understand processing and data product generation algorithms***
***Smart Buyer Staff – Transition of both L7 and EO-1 teams onto LDCM project.***
***Major Risks Retired – ALI has retired significant development and potential “data product “ problems.***
***LDCM able to better judge proposed technology***

## Mission Technologist OperationsLessons Learned

*Mission Technologist Operations**Lessons Learned*

***Do not wage a two front war***
***Make sure its working in the lab before you commit to flight validating it (TRL 6 minimum)***
***Avoid nested technologies***
***Test as though you will have a launch failure***
***Good experience (ALI – excellent pre-launch characterization)***
***Bad experience (PPT - not fully testing EMI/EMC almost postponed validation indefinitely)***
***Keep an eye on the easy stuff***
***Validate as you will operate the target mission***
***Do not bypass Engineering Test Units***
***More proactive risk management and mitigation ***

## Summary

***EO-1 technology results are well publicized and are being infused into future mission proposals and architectures***
***EO-1 Hyperion and LAC data are first benchmark for non-DoD hyperspectral data ***
***EO-1 (and L7) experience and lessons learned enables LDCM mission to proceed as a data buy mission with improved confidence***
***Retired major risks in moving from ETM+ to pushbroom technology***
