The main objective of the TechTIDE project (warning and mitigation technologies for travelling ionospheric disturbances effects) is the development of an identification and tracking system for travelling ionospheric ...
Special Issue on GNSS Data Processing and Navigation
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-08)
Article.
Accés obert
Article.
Accés obert
Global Navigation Satellite System (GNSS) data can be used in a myriad of ways. The current number of applications exceed by far those originally GNSS was designed for. As an example, the present Special Issue on GNSS Data ...
Improvement of retrieved FORMOSAT-3/COSMIC electron densities validated by ionospheric sounder measurements at Jicamarca
(2011-09-01)
Article.
Accés obert
Article.
Accés obert
Inversion 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.
Accés obert
Article.
Accés obert
The 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 ...
Assessing the quality of ionospheric models through GNSS positioning error: methodology and results
(2020-01-01)
Article.
Accés obert
Article.
Accés obert
Single-frequency users of the global navigation satellite system (GNSS) must correct for the ionospheric delay. These corrections are available from global ionospheric models (GIMs). Therefore, the accuracy of the GIM is ...
Global prediction of the vertical total electron content of the ionosphere based on GPS data
(2011-12-29)
Article.
Accés obert
Article.
Accés obert
Although 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 ...
