Experiments on the Ionospheric Models in GNSS
(2013)
Text en actes de congrés
Accés obertIn GNSS, one of the main error sources of the Standard Positioning Service (SPS) is introduced by the ionosphere. Although this error can be cancelled by combining two signals at different frequencies, most of the ... -
