Development of Ionospheric Assimilation and Forecasting System
Abstract
This report was developed under Small Business Innovation Research (SBIR) contract for Topic AFO3-016. This interim report describes current progress in developing an ionospheric modeling and forecasting system sponsored by AFRL. We outline design of the physics-based numerical Ionospheric model that serves as a core of the system and the data assimilation framework for constraining the model with GPS measurements of ionospheric electron content. A newly developed scheme for estimating GPS receiver inter-channel code biases on-line Is presented. The report also describes SOPA/XML web services infrastructure for delivering system simulation results to remote clients. Recently emerged protocol for delivering differential GPS data over the internet, NTRlP, resulted in availability of free sources of real-time GPS streaming data. We describe development efforts for obtaining and utilizing such GPS data. We conclude by outlining a scintillation nowcasting module and challenges related to longer-term forecasting.
