Web11 mrt. 2015 · TEC – total electron content. We have applied W indexing to the EGNOS-TEC map output for producing online the hourly ionosphere-plasmasphere W index maps. The regional distribution of W index is produced at 66 grid points of a map (latitudes 35°N to 60°N in step of 5°, longitude-10°E to 40°E in step of 5°). WebEvery 5 minutes a VTEC matrix with an ionospheric grid point spacing of 2.5° latitude x 5° longitude is generated and stored in ASCII format. Data is provided here with 15 minutes updated rate. Higher temporal resolution can be provided on request. The usage of this product might help to improve the accuracy during GNSS positioning.
