Objective: This study presents the development of data panels to monitor the activities of the ionospheric layer in the western region of Paraná. Theoretical Framework: Since the ionosphere is considered the largest source of systematic error in positioning by GNSS (Global Navigation Satellite System), understanding it is essential for applications in the region, such as controlled machine traffic, dam monitoring, and aerial navigation, among others. Method: A set of metrics was calculated using GNSS observables from the ITAI (Foz do Iguaçu/PR), MSMN (Mundo Novo/MS), and PRCV (Cascavel/PR) stations of the RBMC (Brazilian Network for Continuous Monitoring of GNSS Systems), from 2017 to 2023 (solar cycle 25). Results and Discussion: The data panels made it possible to verify that during the peak of solar cycle 25 (2022-2023), there was a significant increase in metrics: ionospheric delay obtained by the carrier phase (If), ionospheric irregularity index (ROTI), and ionospheric gradient (glf), with peaks between August and April. Research Implications: The analysis of ionospheric gradients also indicates the feasibility of implementing GBAS (Ground-Based Augmentation System) at Foz do Iguaçu International Airport, which will assist in the precision of aircraftapproach and landing. Originality/Value: The results generally provide a structured understanding of ionospheric irregularities, allowing pattern detection and improvement in monitoring.
