Global Ionospheric Specification from GPS and Airglow Data

Abstract

The efficacy of GPS data-processing algorithms with the RIBG model is demonstrated, as is the problem with low latitude ionospheric models, by comparison of predictions from GPS-updated RIBG predictions with independent Topex, and incoherent scatter (ISR) data. Alternate plans are developed to solve the low-latitude model problem, and still retain a practical program for real-time processing of GPS data for ionospheric specification. In the regard, the GPS data-processing algorithms have been revamped for efficiency, now being an order of magnitude faster than before. This enables our program to meet high data throughput requirements for processing and updating GPS data from a global network of GPS receivers for global, near-real-time ionospheric specification. Algorithms have been partially developed to process multistation data for this purpose. The implications of our work for radio systems, ionospheric model development, and other developments are discussed, as well as its relationship to other work in this field.
