History

ISARS was founded in 1955, under the name Ionospheric Institute. In 1990, the Institute was renamed to Institute of Ionospheric and Space Research and in 1999 took its current title in order to reflect its expanded activities, which cover a variety of aspects of space research and applications. The location of the Institute until July 1995 was the historic site of the Hill of Nymphs near the Acropolis of Athens

 and the Theseion. The significant increase of staff members and R&D projects made it necessary for the institute to move to new modern facilities at the NOA campus north of Athens, on Mount Penteli.

The Institute is supervised and supported by the General Secretariat of Research and Technology of the Greek Ministry of Education.

HellENIc GeoMagnetic Array

The National Observatory of Athens operates ENIGMA (HellENIc GeoMagnetic Array), a ground-based magnetometer array in the area of south-eastern Europe (central and southern Greece) for space weather applications. The four existing stations are latitudinally equi-spaced between 30° and 33° corrected geomagnetic latitude and cover the areas of Thessaly

NOAA/AVHRR Image Acquisition Station

The National Observatory of Athens operates an AVHRR image acquisition station manufactured by Telonics Inc. The receiving antenna is installed at ISARS ('Lofos Koufou'). Satellite data from NOAA 12, 14, 15 and 16 are acquired on a daily basis. Images are archived (since 1998), pre-processed (radiometric calibration, navigation, enhancement) and value added products are produced according to user requirements.
