Abstract—The impact of the satellite-based technologies is significantly increasing nowadays, while the satellite signal processing still imperfect. Especially when satellite signals travel through ionosphere layer since Total Electron Contents (TEC) flowing throughout ionosphere layer interrupt these signals. This paper purposes to investigate the characteristics of ionosphere as the temporal analysis during the equinox period which is extremely influence and during the solstice period which is slightly influence to TEC variation compared between solar maximum and minimum. The spatial analysis used the GPS data from different geographic latitude in the middle latitude region where the variation of TEC is pretty quiet and calm. The results show TEC distribution during solar maximum was greater and more violent than that in solar minimum. The peak values mostly occurred in April and September while the lowest value period occurred in June. Furthermore the exploration of the diurnal analysis during solar maximum increased regularly from noon until dusk while solar minimum also rose up at noon to dusk. Mostly TEC variation had the same pattern but only some latitude appeared unconventional.

Index Terms—Equinox, TEC, solar activity, sunspot number.
