THE SCOPE OF THIS EFFORT INCLUDES TASKS TO COMPLETE THE 21-CM COSMOLOGY INSTRUMENT PRELIMINARY DESIGN, WITHIN REQUIREMENTS WITH APPROPRIATE MARGINS, ACCEPTABLE RISKS, AND WITHIN COST AND SCHEDULE RESTRAINTS. TO THIS END, NRAO HAS IDENTIFIED THE WORK REQUIRED DURING THIS TIME PERIOD FOR THE INSTRUMENT BASED ON THE DIFFERENCES BETWEEN COMPONENT DESIGN ENVIRONMENTS AND THE EXPECTED OPERATING ENVIRONMENT. THIS WORK FOCUSES ON THE PRELIMINARY DESIGN AND TESTING OF THE RF SIGNAL PROCESSING/CALIBRATION & DSP DEVELOPMENT/EVALUATION PLATFORM. IT INCLUDES DEVELOPMENT OF TWO PRE-FLIGHT PROTOTYPE MODULES FOR RF SIGNAL PROCESSING/CALIBRATION AND ONE DSP DEVELOPMENT/EVALUATION PLATFORM FOR DEFINING AND VERIFYING THE APPROACHES TO DATA ACQUISITION, REAL TIME ANALYSIS, AND STORAGE (SEE FIGURE 1). THE FOLLOWING SPECIFIC WORK ELEMENTS ARE PROPOSED TO FURTHER DEVELOP THE RF SIGNAL PROCESSING/CALIBRATION AND THE DSP DEVELOPMENT/EVALUATION PLATFORM: 1. NRAO SCIENCE PRINCIPAL INVESTIGATOR (PI) OVERALL SCIENTIFIC LEAD FOR WORK AT NRAO. THE NRAO PI ENSURES THAT THE RF SIGNAL PROCESSING/CALIBRATION ALONG WITH DSP DEVELOPMENT/EVALUATION PLATFORM MEETS THE SCIENTIFIC MISSION OF 21-CM COSMOLOGY INSTRUMENT. 2. NRAO PROJECT MANAGEMENT (PM) OVERALL PROJECT MANAGEMENT OF WORK PERFORMED AT NRAO, INCLUDING, BUT NOT LIMITED TO, TEAM COORDINATION AND COMMUNICATION, PROJECT REVIEWS, FINANCIAL REPORTING, AND TRAVEL. DELIVERABLES INCLUDE: " MONTHLY FINANCIAL REPORTS TO NASA PM; " SCHEDULE INPUTS TO NASA PM; " INPUTS TO RISK REGISTER AND ASSOCIATE MITIGATION PLANS. 3. NRAO SYSTEMS ENGINEERING (SE) OVERALL SYSTEMS ENGINEERING SUPPORT OF THE WORK PERFORMED AT NRAO AND COORDINATION OF DESIGN WORK AND INTERFACES AT PARTNER INSTITUTIONS. WORK INCLUDES, BUT NOT LIMITED TO, SYSTEMS ENGINEERING OF THE RF SIGNAL PROCESSING AND CALIBRATION ALONG WITH DSP DEVELOPMENT AND EVALUATION PLATFORM. THE NRAO SE WILL INTERFACE WITH THE NASA SE TO ENSURE COMPONENT AND SUBSYSTEM LEVEL REQUIREMENTS ARE MAPPED AND TESTED. DELIVERABLES INCLUDE: " COMPONENT- AND SUBSYSTEM-LEVEL REQUIREMENTS; " INTERFACE CONTROL DOCUMENT INPUTS. 4. EMI SUPPRESSION FOR RF SUBSYSTEMS ASSESS THE EMI POTENTIAL OF THE LCM, CRM, AND THERMAL CONTROL SYSTEM AND DEVELOP EFFECTIVE MITIGATION ACTIONS INCLUDING FILTERS, FERRITES, AND THE ELIMINATION OF GROUND LOOPS. DELIVERABLES INCLUDE: " RF SUBSYSTEM EMI SUPPRESSION MITIGATION ASSESSMENT AND LAB TEST DATA. SPECIFIC TASKS INCLUDED IN THIS WORK ELEMENT ARE AS FOLLOWS: A. ASSESSMENT OF THE EMI ENVIRONMENT ON-BOARD THE SPACECRAFT, IDENTIFY REQUIRED MEASUREMENTS. B. MEASUREMENT OF RFI FROM SPACECRAFT SUBSYSTEMS. C. DEVISE OVERALL FILTERING AND SHIELDING TO MITIGATE COUPLING OF RFI INTO THE RF MODULES. D. IMPLEMENT AND TEST OF LCM AND CRM MODULES FOR COMPLIANCE. E. REVISE EMI MITIGATION, IF NECESSARY. F. FINAL RFI MEASUREMENTS OF LCM AND CRM MODULES FOR COMPLIANCE. 3 5. DEVELOPMENT OF THE PATCH ANTENNA ASSESS THE FEASIBILITY OF USING A PATCH ANTENNA. DELIVERABLES INCLUDE: " ENGINEERING MODEL SPECIFIC TASKS INCLUDED IN THIS WORK ELEMENT ARE AS FOLLOWS: A. DESIGN PATCH ANTENNA ENGINEERING MODEL (EM). B. CONSTRUCT ENGINEERING MODEL PROTOTYPE. C. CONSTRUCT SCALE MODEL FOR RADIOMETRIC TESTS. D. PERFORM FUNCTIONAL TESTS ON PROTOTYPE. E. INTEGRATE PROTOTYPE WITH LCM, CRM AND SIGNAL PROCESSING SYSTEM. F. PERFORM SUBSYSTEM FUNCTIONAL TESTS. G. MODIFY PATCH ANTENNA ENGINEERING PROTOTYPE FOR CTP FIELD INSTALLATION. H. MODIFY PATCH ANTENNA DESIGN FOR DAPPER FORM, FIT, AND FUNCTION. I. [TBD LATER] FABRICATION OF TRL6 PROTOTYPE. 6. DEVELOPMENT/EVALUATION PLATFORM AND SOFTWARE FOR THE DSP BACKEND IT IS NECESSARY TO DEVELOP AND VERIFY THE COMPLETE SIGNAL PROCESSING REQUIREMENTS AND OPERATIONAL PATHWAY FOR THE SCIENCE INSTRUMENT BACK-END BEFORE FLIGHT PLATFORM IMPLEMENTATION. THIS SYSTEM WILL ALSO BE USED TO VERIFY COMPLIANCE OF THE SCIENCE INSTRUMENT FRONT-END (WP6). DELIVERABLES INCLUDE --> PLEASE EMAIL OCGSUBS@COLORADO.EDU FOR REMAINDER OF STATEMENT OF WORK.
