Comparative testing of four ionospheric models driven with GPS measurements
(2011-07-28)
Article
Open AccessIn the context of the European Space Agency/European Space Operations Centre funded Study “GNSS Contribution to Next Generation Global Ionospheric Monitoring,” four ionospheric models based on GNSS data (the Electron ... -
Comparison of GPS analysis strategies for high-accuracy vertical land motion
(2008-01)
Article
Open AccessTide gauges measure sea level changes relative to land. To separate absolute changes in sea level from vertical land movements tide gauges are often co-located with Continuous GPS (CGPS). In order to achieve an accuracy ... -

Distribution and mitigation of higher-order ionospheric effects on precise GNSS processing
(2014-04)
Article
Open AccessHigher-order ionospheric effects (I2+) are one of the main limiting factors in very precise Global Navigation Satellite Systems (GNSS) processing, for applications where millimeter accuracy is demanded. This paper summarizes ... -

Global prediction of the vertical total electron content of the ionosphere based on GPS data
(2011-12-29)
Article
Open AccessAlthough vertical total electron content (VTEC) forecasting is still an open subject of research, the use of predictions of the ionospheric state at a scale of several days is an area of increased interest. A global VTEC ... -

Improvement of retrieved FORMOSAT-3/COSMIC electron densities validated by ionospheric sounder measurements at Jicamarca
(2011-09-01)
Article
Open AccessInversion techniques applied to GPS‐LEO radio occultation data allow the retrieval of accurate and worldwide‐distributed refractivity profiles, which, in the case of the ionosphere, can be converted into electron densities ... -
Integrity monitoring for carrier phase ambiguities
(2012-01)
Article
Open AccessThe determination of the correct integer number of carrier cycles (integer ambiguity) is the key to high accuracy positioning with carrier phase measurements from Global Navigation Satellite Systems (GNSS). There are a ... -

Ionospheric and plasmaspheric electron contents inferred from radio occultations and global ionospheric maps
(2015-07-04)
Article
Open AccessWe introduce a methodology to extract the separate contributions of the ionosphere and the plasmasphere to the vertical total electron content, without relying on a fixed altitude to perform that separation. The method ... -
