IGF::OT::IGF SUSTAINABLE LAND IMAGING (SLI) - REDUCED INSTRUMENT ENVELOPE STUDY: THE CONTRACTOR SHALL PERFORM ONE OR MORE CONCEPTUAL DESIGNS OF IMAGER INSTRUMENTS TARGETING A REDUCED VOLUME, MASS, AND POWER ENVELOPE THAT CAN SATISFY LAND IMAGING PERFORMANCE REQUIREMENTS AND MEET NPR 8705.4 RISK CLASS B STANDARDS. THE CONTRACTOR SHALL ASSUME THE CONCEPT OF OPERATIONS FOR THE INSTRUMENT. THE CONTRACTOR SHALL PROVIDE IMAGING ALL LAND AND COASTAL AREA IN THE INSTRUMENTS FIELD OF VIEW, EVERY ORBIT. THE CONTRACTOR SHALL ASSUME AGILITY, MECHANICAL INTERFACE TO S/C, THERMAL INTERFACE TO S/C, AND ELECTRICAL INTERFACE TO SPACECRAFT (S/C). AS PART OF THIS DESIGN, THE CONTRACTOR SHALL PERFORM ANALYSIS AND PROVIDE STUDY PRODUCTS ADDRESSING AT A MINIMUM SLI PERFORMANCE REQUIREMENTS TO IDENTIFY THE DRIVERS FOR MASS, VOLUME, AND POWER, AND COST FOR FUTURE MID-TERM INSTRUMENT DESIGNS. THE CONTRACTOR SHALL PROVIDE A DETAILED ASSESSMENT OF OPTICAL DESIGN AND FOCAL PLANE PERFORMANCE RELATIVE TO SLI PERFORMANCE REQUIREMENTS. THE CONTRACTOR SHALL PERFORM ANALYSIS AND PROVIDE STUDY PRODUCTS ADDRESSING EMERGING TECHNOLOGIES AND TECHNIQUES TO FURTHER ENABLE IMPLEMENTATION EFFICIENCIES AND A SCHEDULE FOR POTENTIAL INFUSION INTO SLI. THE CONTRACTOR SHALL ACCOMMODATE ON-BOARD REFLECTIVE AND THERMAL BAND CALIBRATION SOURCES TO SATISFY PERFORMANCE REQUIREMENTS. THE CONTRACTOR SHALL DISCUSS CALIBRATION APPROACH AND DEVELOP A CALIBRATION ERROR BUDGET. THE CONTRACT SHALL ASSESS THERMAL CONTROL, INCLUDING TECHNIQUES AND TECHNOLOGIES FOR DETECTOR COOLING AND STABILIZATION, ACCOMMODATION OF POTENTIALLY LARGE RADIATOR AREAS ON A SMALLSAT PLATFORM, ASSESSMENT OF PASSIVE VS. ACTIVE COOLING ON A SMALLSAT PLATFORM. THE CONTRACTOR SHALL IDENTIFY SPACECRAFT INTERFACE ASSUMPTIONS, INCLUDING THOSE FOR ATTITUDE CONTROL AND LINE OF SIGHT STABILITY, AND RATIONALE FOR SATISFYING IMAGING REQUIREMENTS. THE CONTRACTOR SHALL DELIVER BRIEF MONTHLY UPDATED STATUS PACKAGES. THE CONTRACTOR SHALL HOST A KICKOFF MEETING. THE CONTRACTOR SHALL SUPPORT A PRELIMINARY RESULTS (MIDTERM) REVIEW. THE CONTRACTOR SHALL HOST A FINAL RESULTS REVIEW. SPECIFIC ACTIVITIES SHALL BE PRIMARILY PERFORMED AT THE CONTRACTOR S LOCATION.
