This paper studies the behavior of the vertical total electron content obtained with GPS satellites signals (GPSTEC) and total electron content derived from Digisondes (ITEC).. The data base includes ionograms and GPS observations recorded  at El Arenosillo, Spain (37.1N; 353.3E) and Pruhonice, Check Republic (50.0° N; 15.0°E) during different seasonal and solar activity conditions. Comparisons between observations and the IRI total electron content predictions (IRITEC) have been also done. The shapes of the three estimations are similar and, as it is known, the GPS values are greater than the ITEC values. The IRI predictions generally overestimate the ITEC values. The differences between GPS TEC and ITEC are analyzed.
