Corrección de retardos ionosféricos en radio señales de objetos celestes : estimación del TEC y obtención de la rotación de Faraday de señales GPS en la ionosfera sobre el Ecuador.

Abstract

The study conducted involved collecting GPS signal data from four stations located in Ecuador: EPEC, LJEC, SIEC, and SNLR. These data were obtained in RINEX format and used to estimate the Total Electron Content (TEC) during various time periods. Using the TEC data from these stations and magnetic field values, the Faraday rotation angle experienced by radio signals used by GPS was estimated. There was variation in the values obtained between the stations, especially when comparing SNLR(located in northern Ecuador) with SIEC (located in southern Ecuador). The SIEC station was chosen due to inconsistencies with LJEC data. Additionally, a relationship between TEC values and natural phenomena such as solar activity was observed. This study highlights the importance of TEC and Faraday rotation as key indicators for understanding ionospheric dynamics and their connection to solar activity.
