             abstract = "An approach for testing the robustness of GNSS receivers under 
                         ionospheric scintillation was implemented using a GNSS simulator 
                         and receiver raw data recorded during previous scintillation 
                         events at low latitudes. The GNSS simulator allows to reproduce RF 
                         signals from a GNSS constellation under standard ionospheric 
                         conditions. In this work, it is intended to reproduce RF signals 
                         under scintillation. This requires the data treatment of the 
                         amplitude and phase variations of receiver raw data GNSS signals 
                         formerly acquired. Such actual data is employed as an input to the 
                         GNSS simulator in order to modify one or more channels that are 
                         simulated. Therefore, it was possible to test a given GNSS 
                         receiver reproducing past scintillation conditions and providing 
                         test reproducibility. These tests allow to demonstrate a good 
                         agreement between the performance of the considered GNSS receiver 
                         under real and simulated ionospheric scintillation conditions. The 
                         proposed approach was successfully evaluated by a variety of tests 
                         applied to different GNSS receivers, including one low-cost 
                         receiver under development. This work may contribute to real time 
                         testing of algorithms intended for Total Electron Content (TEC) 
                         calculation, scintillation alerts, prediction and mitigation, as 
                         well as Ground Based Augmentation System (GBAS) evaluations.",
