                         deployed in Brazil, are presented here the characteristics of the 
                         400 m ionospheric irregularities during magnetically quiet and 
                         disturbed conditions. The network is composed of 12 GPS 
                         scintillation monitors and covers the latitudinal region from the 
                         magnetic equator up to the southern crest of the Equatorial 
                         Ionization Anomaly (EIA), which is characterized by large 
                         horizontal gradients in the electron density distribution. Some 
                         results on equatorial spread-F statistics obtained from digisonde 
                         data over Cachoeira Paulista (22.41o S, 45o W, dip latitude 14.89o 
                         S) and from ionosonde data over Tucum{\'a}n (64.5o W, 27o S, dip 
                         latitude 13.71o S) are also used in this work to complement the 
                         results from GPS network. The effects of local time, season, 
                         latitude, longitude, background ionization, solar cycle and 
                         magnetic activity on the ionospheric irregularities are presented. 
                         The ionospheric irregularity zonal velocities determined by 
                         magnetically east-west spaced GPS receivers are also presented. 
                         The influence of the ionospheric irregularities on GPS based 
                         navigational systems is discussed. These observations, 
                         complemented by computational simulations, may improve our 
                         understanding of the factors responsible for the generation, 
                         growth and dynamics of the equatorial F-region plasma
