This paper describes the design, analysis, and evaluation of new ionospheric measurement error models for high-integrity multiconstellation navigation systems, The robustness of the newly derived models is experimentally evaluated using months of dual-frequency global positioning system (GPS) data collected at multiple locations, In parallel, an integrity analysis is devised to quantify the impact of traveling ionospheric disturbances on user position, Finally, overall carrier phase positioning performance is assessed over continental areas for various combinations of GPS and Galileo and Iridium satellites.
