Total electron content in Australia corrected for receiver/satellite offset bias and compared with IRI and PIM predictions Original Research Article

A procedure is presented for removing receiver and satellite (transmitter) offset bias from total electron content (TEC) data obtained using Global Positioning System (GPS) satellites from 1991 to 1998. Samples of TEC data from 1991 to 1995 for Australia have been corrected for bias. Corrected TEC values show substantial agreement with model predictions from the International Reference Ionosphere (IRI) and the Paramaterized Ionospheric Model (PIM).
