National Reconnaissance Office Technology SeminarJuly 11, 2005
• Model development – Global Assimilative Ionosphere Model– AFOSR/ONR-sponsored MURI 5-year development program
• C/NOFS augmentation: C/NOFS data into GAIM
NRO Technology Seminar July 11, 2005
• AFRL Collaboration (Task manager: Bill Borer)• C/NOFS satellite: Goal is forecast of scintillation• Investigating use of GAIM for background density field
• Critical for accurate forecasts
• Input C/NOFS Datatypes:• GPS occultation• In situ density• Vector Electric fields, vertical drift velocity• Tri-band beacon (ground-LEO TEC links)
• Close collaboration• Source code transfer• Jointly-conducted analysis• Technology transfer (source code, expertise, data sets…)
