Resumen:
SIRGAS is responsible of the terrestrial reference frame of Latin America and the
Caribbean. To fulfil this commitment it manages a continuously operational GNSS network with more
than 200 receivers. Although that network was not planed for ionospheric studies, SIRGAS attempted
to exploit it by establishing, in early 2008, a regular service for computing regional maps of the vertical
Total Electron Content. This paper describes an effort for developing a new SIRGAS product,
concretely, a 4-dimensional (space and time) representation of the free electron distribution in the
ionosphere. The working methodology is based on the ingestion of dual-frequency GNSS observations
into a global electron density model in order to update its parameters. Preliminary results are
presented and their quality is assessed by comparing the electron density computed with the
methodology here described and the one estimated from totally independent observations. A
preliminary analysis reveals that the performance of the electron density model improves by a factor
greater than 2 after data ingestion.
