                         Network (GMDN), was installed in 2001 at the Southern Space 
                         Observatory (SSO/INPE) in S{\~a}o Martinho da Serra. Since its 
                         installation, the detector has undergone several upgrades to 
                         enhanced sensitivity, stability, and data quality. The most recent 
                         upgrade, carried in collaboration with Shinshu University (Japan), 
                         involved the replacement of the old acquisition system with a new, 
                         high perfomance electronics system provided by our Japanese 
                         partners. This modernization significantly improved the detector 
                         directional resolution, and the counting rate stability, enabling 
                         more precise measurements of cosmic ray flux and solar modulation
