6. Cal/Val Complexity 26 EDRs 4 New Instruments
3 Resource Management Centers
Pre-launch tests occurring at 4 different sensor vendors
How are we managing this?
How do we know our plans are comprehensive?

7. Coordinated NPP Cal/Val Plan
Baseline and Changes
Coordinated NPP Cal/Val Plan Baseline
The SSPR Prime contractor, the Integrated Program Office, and the NAS NPP Science team have a (mostly) common interest in executing a successful Cal/Val
SDR/EDR Compliance-to-Cal/Val Requirement system engineering (with Science and Technical Advisors involvement) will identify tasks that are must, specific, realistic, and measurable. A Tasks Network will be used to explore schedule constraints and clearly define task responsibilities
The CVMT and Science/Technical Advisors are responsible for constraint management
Looking for synergistic tasks. Exploring parallel task execution options
Identifying discrepancies in bottom-up schedule, budget and Goals
Using priorities to explore trade-offs
Using NPOESS SCB and NETS to resolve schedule and budget gaps
From the Task Network the CVMT will establish roles and responsibilities among performing organizations
The CVMT will manage execution of the Joint NPP Cal/Val Plan baseline
Joint NPP Cal/Val Plan Baseline changes
The CVCCB will manage baseline changes employing traditional CCB processes and documentation

9. “Bottom Up” approach to defining Cal/Val
Driven by diagnostic work that has to be done in the intensive post-launch phase

10. Tasks are captured in a web-based relational database
Attributes include Data, metadata, tools, entry and exit criteria, etc.

11. Once described, tasks are linked logically and scheduled
Technical threads are rigorously developed and reviewed by joint teams with individuals from NGST, sensor vendors, Academia, Gov’t Labs, and FFRDCs.
ATMS Thread

12. A technical library supports the distributed Cal/Val Team
Sensor data, analyses, algorithms, formats, tools, reports

13. The technical library includes the algorithms and their supporting documentation:
ATBDs, code, test data, formats, results, etc.

14. All code, including algorithms and tools is under configuration control for Cal/Val

15. Cal/Val Anomaly Resolution
& Ops Change
The IPO/NASA/NGST SSPR Cal/Val Team will perform analysis and validation of calibration and SDR/EDR performances
Cal/Val anomalies will be investigated by expert SSPR CV Anomaly Resolution Teams
Anomaly findings and resolutions will be submitted to the CVCCB for consideration and subsequent recommendation to the ACCB and the O&S CCB for operational implementation

Are there Cal/Val concerns specific to the Direct Readout community?
Global look-up tables
Radiometric calibration consistency
Cross-instrument geolocation
What can the direct readout community bring to the Cal/Val program?
