TEC Disturbance Index
This index is defined as the mean deviation of the current conditions for the Total Electron Count (TEC) in the ionosphere from a 15-day running median reference data. An index of 1.5 mean there is a deviation of 150% between the current and the average TEC values. It is representative of the deviation of current ionospheric conditions from those expected by an usual GPS receiver. This deviation can cause a position error if it remain uncorrected. For the real GPS position errors refer to the L1 map below.

Current S4 Index (Ionosphere)
S4 Index
Ionospheric scintillation occurs when a radio frequency signal traverses a region of small scale irregularities in electron density in the ionosphere. This is a rapid fluctuation of radio-frequency signal amplitude. The S4 Index quantified this amplitude scintillation with a measure of the short timescale fluctuation in the signal to noise of a transmission. Values over 0.6 indicate strong scintillation which can cause loss of lock on a GPS signal. A scintillation index below 0.3 is unlikely to have any affect on GPS.
