| Resumo | The ionosphere affects the propagation of GPS signals in the equatorial and low-latitude regions. Even auxiliary systems such as the Ground Based Augmentation System (GBAS), are affected by ionospheric effects, which are the focus of the present contribution. For all active channels between GPS satellites and receivers, models for the pseudorange, carrier phase, and received power of the GPS L1 signal will be described, considering the geometric range; receiver and satellite clock errors, ionospheric and tropospheric delays; multipath; phase and amplitude scintillation; and system parameters. To simulate ionospheric delays, the vertical Total Electron Content is characterized through a statistical analysis of dual-frequency GPS data from the Rede Brasileira de Monitoramento Cont´ınuo and their residuals relative to those provided by the International Reference Ionosphere (IRI 2016). This study considers different combinations of five geophysical parameters. The α − µ probability distribution model is used to represent amplitude scintillation. To define the parameters of this distribution, a random value for the S4 index (the standard deviation of the received power, normalized by its average value) and the associated value for α and µ are selected, according to data from the CIGALA/CALIBRA network. Successive samples for the phase scintillation term are generated similarly, according to empirical relationships between S4 and σφ (the standard deviation of phase fluctuations) values, combined with zero-mean Gaussian probability distributions. Next, the functions of a GBAS (Signal-in-Space Receive and Decode; Signal Quality Receiver; Signal, Measurement, and Data Quality Monitoring; Multiple Reference Consistency Check) will be described. The functional blocks are integrated by the Executive Monitor to test, smooth, correct, and average signals, as well as to estimate protection levels and to generate correction messages that will be transmitted to aircrafts via a Very High Frequency Data Broadcast link. Finally, this contribution will present and discuss results from the above formulation for different combinations of geophysical parameters and configurations of interest. | |||
