GPS ionospheric tomography: A comparison with the IRI-2001 model over South Korea
The International Reference Ionosphere model 2001 (IRI-2001) is one of the most comprehensive empirical models of the ionosphere and has been widely used to estimate the electron density profiles in the altitude ranging from about 60 to 2000 km and the total electron content (TEC) at any given location, time and date, which reflect smooth-average global ionospheric behaviors. However, whether i...
متن کاملComputerized Ionospheric Tomography
ith the transition to the Global Positioning System, Transit has been decommissioned, after having served well for the Fleet. A new system, the Navy Ionospheric Monitoring System, was established using Transit satellites. This article examines the application of the new system to the field of computerized ionospheric tomography. (
متن کاملIonospheric Correction Using Tomography
The most demanding application of wide area di erential corrections to GPS is vertical positioning of aircraft on precision approach. Here the Wide Area Augmentation System (WAAS) combines accuracy requirements on the order of ones of meters with safety of life integrity requirements which specify that any vertical position errors greater than the Vertical Protection Limit be enunciated to the ...
متن کاملVariation of ionospheric slab thickness over South Africa
Ionospheric slab thickness is defined as the ratio of TEC to maximum electron density of the F-region (NmF2), proportional to the square of the F2-layer critical frequency (foF2). It is an important parameter in that it is linearly correlated with scale height of the ionosphere, which is related to electron density profile. It also reflects variation of the neutral temperature. Therefore, ionos...
متن کاملAccurate reference ionospheric model for testing GNSS ionospheric correction in EGNOS and Galileo
This work presents a procedure to assess ionospheric models tailored for Global Navigation Satellite System (GNSS) applications. The test is based on actual carrier-phase measurements. Using this strategy, the accuracy of the ionospheric broadcast models for Global Positioning System (GPS), Galileo and the European Geostationary Navigation Overlay System (EGNOS) is assessed. These models are co...
