             abstract = "After sunset, in the equatorial regions ionospheric plasma 
                         irregularities are generated due to the generalized 
                         Rayleigh-Taylor instability. Under favorable conditions these 
                         irregularities develop in the equatorial region while mapping 
                         along the magnetic field lines giving rise to large plasma 
                         depletion structures called Equatorial Plasma Bubbles with 
                         embedded smaller structures on their walls. The global navigation 
                         satellite system (GNSS) L1 band frequency is sensitive to 
                         irregularities of the size of 300-400 m in the first Fresnel zone, 
                         which cause scattering and diffraction of the signal and produce 
                         amplitude and/or phase scintillation. Severe scintillation of GNSS 
                         signals can in turn cause loss of lock of the receiver code and/or 
                         carrier loops. As a result, GNSS navigation and positioning 
                         solution can be adversely affected by the ionospheric 
                         scintillation. There are multiple GNSS receivers designed to 
                         monitor scintillations. These receivers are based on different 
                         hardware designs and use different methodologies to process the 
                         raw data. When using simultaneous data from different GNSS 
                         scintillation monitors it is important to evaluate and compare 
                         their performances under similar scintillation conditions. The 
                         scintillation monitoring techniques may be useful for many 
                         applications that use GNSS signal. The aim of this work is to 
                         evaluate the performance of six different GNSS receivers located 
                         at Sao Jose dos Campos (23.1 degrees S, 45.8 degrees W, dip 
                         latitude 17.3 degrees S) during moderate and strong scintillation 
                         activity. The amplitude (S-4) and phase (sigma(phi)) scintillation 
                         indexes from these receivers were analyzed and compared for the 
                         nights February 20-21 and November 27-28, 2013.",
