ABSTRACT: The National Polar-Orbiting Operational Environmental Satellite System (NPOESS) Science Investigator-led Processing System (NSIPS) is developed to support the Northrop Grumman Space Technology (NGST)-led on-orbit calibration and validation (cal/val) effort for the NPOESS Preparatory Project (NPP) and NPOESS in support of the tri-agency Integrated Project Office for DoD, DOC, and NASA. NSIPS is deployed at the NOAA Satellite Operations Facility (NSOF) in Washington, DC, collocated with the NPOESS IDPS and other remote sensing data centers for easy access to large volume of data needed in our Cal/Val effort.
This paper describes NSIPS capabilities for ingest, archive, processing, and delivery of Cal/Val relevant data, and the daily operation of NSIPS. Current status is provided on the development and testing of various interfaces between NSIPS and other data archiving and processing systems that support the NGST Cal/Val efforts for NPP and NPOESS.
A description and assessment of NSIPS capabilities to support NPP/NPOESS operational algorithm changes and validation of these changes is included. |

ABSTRACT: The Government Resource for Algorithm Verification, Independent Testing, and Evaluation (GRAVITE) provides the NPOESS Integrated Program Office (IPO) with a technical infrastructure for the conduct of the IPO NPOESS Preparatory Program (NPP) Calibration and Validation (Cal/Val) Program, and a mechanism for providing support to the NASA and NPOESS prime contractor efforts as determined appropriate by IPO management.
The GRAVITE consists physically of a remote computing center at the NOAA Satellite Operations Facility in Suitland, Maryland, a web and file server system, known as CasaNOSA, a user work area in IPO office space on the 14th floor of the Centre Building in Silver Spring, Maryland, and several remote computers at analysis and sensor vendor facilities around the country. Computers at the various GRAVITE facilities communicate via secure connections to the Internet, and in some high bandwidth scenarios, dedicated point-to-point communication links.
The GRAVITE hosts software applications and databases intended to disseminate relevant technical information to the broader NPP Cal/Val community, and optimize the IPO's analysis resources. Specifically, the GRAVITE consists of a technical library of all NPP and related documentation, an indexed archive of all pre-launch test data from the NPP instruments and spacecraft, and a revision controlled repository of data processing and analysis software. Additionally, GRAVITE will provide resources for the storage and distribution of NPP mission and correlative data amongst the IPO Cal/Val team, and a central data processing and reduction capability to augment the capability of individual investigators.
With a target mission readiness date of October 2009, detail planning is currently underway in coordination with the IPO NPP Cal/Val team and their subject matter experts. Detailed technical plans are intended for release in late September 2008 for review in concert with the overall cal/val plan at an IPO sponsored NPP community cal/val symposium in October, 2008. |
