Abstract
In order to optimize GPS (Global Positioning System) time transfer ove r an intercontinental baseline (France to Japan, about 8800 km), we su pplement commercial C/A code receivers with dual frequency codeless re ceivers designed to measure directly the ionospheric delay of the GPS signal. Using data accumulated over a period of two and a half years, we show that the long-term precision of time transfer can be improved through the use of these ionospheric measurements.
