The paper presents the comparison between total electron content (TEC) map given by CODG model and Rinex TEC obtained from Koudougou GPS station, which started its operations in Decembre 2008. The TEC observations were carried out at Koudougou station during 5-10 December 2008 by ionosphere single layer model (SLM). The observation of TEC profiles showed noon bite out profile with predominance of morning or afternoon peak and night time peak. CODG TEC profiles highlighted dome and reverse profiles. There is no night time peak in TEC map profiles. The comparison between GPS base TEC observation et Koudougou station and TEC map shows that CODG model does not estimate Rinex TEC at Koudougou station.
