Abstract. Previous studies utilizing the Global Positioning System (GPS) receivers aboard Jason satellites have performed measurements of plasmasphere electron content (PEC) by determining total (TEC) above these satellites, which are at altitudes about 1340 km. This study uses similar methods to determine PEC for Jason-2 receiver 24 July 2011. These values compared previous determinations from...

Electron density distribution is the major determining parameter of the ionosphere. Computerized Ionospheric Tomography (CIT) is a method to reconstruct ionospheric electron density image by computing Total Electron Content (TEC) values from the recorded Global Positioning Satellite System (GPS) signals. Due to the multi-scale variability of the ionosphere and inherent biases and errors in the ...

[1] At 17:47 UT on 20 September 1999, a large earthquake of magnitude Mw 7.6 struck the central Taiwan near a small town of Chi‐Chi. The ground‐based receivers of the global positioning system (GPS) in the Taiwan area detected coseismic ionospheric disturbances (CIDs) in the total electron content (TEC) triggered by the Chi‐Chi earthquake. When the CIDs travel away from the origin on the Earth ...

The equatorial anomaly is the dominant structure in free electron concentration in the tropical ionosphere. Due to its edges (crests) which are characterised by steep latitudinal gradients in TEC and are temporally and spatially variable, it is one of the ionospheric regions most difficult to image with inversion methods. In this paper we reconstruct an International Reference Ionosphere model ...

The total electron content (TEC) maps can be used to estimate the signal delay of GPS due ionospheric between a receiver and satellite. This result in positioning error. Thus, it is important monitor TEC maps. observed have big patches missingness ocean scattered small areas on land. In this paper we propose several extensions existing matrix completion algorithms achieve map reconstruction, ac...
