“…R B and T B , respectively, are corrections for receiver and transmitter (satellite) biases. Breed et al (1997) have clearly described the methods used here to determine the instrumental (receiver and transmitter) biases. Furthermore, pre-processing of the GPS data is also performed to detect and remove, or correct signal outliers and signal cycle slips.…”

Abstract. The ionospheric storm evolution process was monitored during the 22 September 1999 magnetic storm over the Australian eastern region, through measurements of the ionospheric Total Electron Content (TEC) from seven Global Positioning Systems (GPS) stations. The spatial and temporal variations of the ionosphere were analysed as a time series of TEC maps. Results of our analysis show that the main ionospheric effect of the storm under consideration are: the long lasting negative storm effect during a magnetic storm at mid-latitude regions; the strong, positive disturbances during the storm's main phase at auroral latitude regions; the effects of storm-induced equatorward directed wind causing a positive disturbance at high and mid-latitude stations with appropriate time shift between higher and lower latitudes; daytime poleward movement of depleted plasma that causes temporary suppression of the equatorial anomaly during the start of the storm recovery phase; and prompt penetration of eastward electric fields to ionospheric altitudes and the production of nearly simultaneous TEC enhancement at all latitudes. In general, we found dominant negative disturbance over mid and high latitudes and positive disturbance at low latitudes. A comparison of storm-time behaviour of TEC determined from GPS satellites, and f o F 2 derived from ionosondes at a range of latitudes, showed reasonable agreement between the two independent measurements.

“…TEC can be derived from transionospheric GPS signals recorded at ground-based GPS receivers (Klobuchar, , 1996Breed et al, 1997;Makela and Kelley, 2001). Methods of TEC calculation from GPS observations have been described in detail in several papers (Sardón et al, 1994, Breed et al, 1996 and the reference therein).…”

“…All the TEC values used for the present study have been corrected from biases using satellite and receiver bias values obtained from the data center of Space Science Laboratory, Department of Physics, Barkatullah University, Bhopal. The methods by which the instrument biases can be removed from the measured TEC values have been explained in detail in [5] [6].…”
