In recent years several authors have developed strategies that estimate the Integrated Water Vapor (IWV), proportional to the Zenith Tropospheric Delay (ZTD), in near real time --i.e. with a delay of one hour or more--. The success of these estimatio

We intend to present results of a study where precise ionospheric corrections have been generated and then used to assist Global Navigation Satellite System (GNSS) positioning with data from high-end single-frequency receivers. The data used in the t

A procedure for resolving carrier phase ambiguities, even under unfavorable geomagnetic conditions, has been tested. Precise ionospheric corrections have been made using dual-frequency data from control stations. Successful results will be presented,
