Tucumán Ionospheric Observatory

Latitude: 26.9° S, Longitude: 294.6° E (San Miguel de Tucumán, Argentina)

The ionospheric station of Tucumán is located in San Miguel de Tucumán, approximately 1.200 km north-west from Buenos Aires, Argentina. It plays a particularly important role both for its position near the southern peak of the equatorial anomaly, and for being one of the few ionospheric monitoring stations in South America. At the end of 2014, the Station has been moved to the FACET-UNT campus (Universidad Nacional de Tucumán) from FRT-UTN (Universidad Tecnológica Nacional), the place where it used to operate since its foundation.

The ionospheric station is installed in the Facultad de Ciencias Exactas y Tecnología (FACET) of the Universidad Nacional de Tucumán (UNT) in scientific collaboration with Facultad Regional Tucumán-Universidad Tecnológica Nacional (UTN). The Universidad Nacional de Tucumán has been demonstrating a great interest in the ionospheric studies and observations since 1957 (the International Geophysical Year). For this reason it has become a constant reference for all South American cone in the ionospheric field.

Under an Argentine Italian scientific collaboration agreement sponsored by the Istituto Italo Latino Americano (IILA) the ionospheric station in Tucumán has been restored in August 2007. It was installed first at the FRT-UTN, and a few years later it was moved to the FACET-UNT.

The sounding system is formed by an AIS-INGV ionosonde. The ionograms are autoscaled real time by Autoscala software, that sends the results of the elaboration made on the experimental trace to a server of the Istituto Nazionale di Geofisica e Vulcanologia of Rome.

The system of antennas, designed at INGV and realized from Argentine engineers, is constituted of two delta antennas lying on orthogonal plans put on a backstayed mast.
