On 25 and 26 September 2025 Krea University successfully installed a multifrequency Global Navigation Satellite System receiver at the Sri City campus. The instrument is a calibrated state of the art GNSS receiver which can be operated as a reference system. This will be measuring multiple L-band radio frequencies emitted by different global satellite based positioning and timing systems such as GPS, GLONASS, Galileo, Beidou, NAVIC and QZSS. From the measurements, total electron content of the ionosphere can be estimated as a routine 24/7 data product.
This will boost the ongoing space research activities in Krea University and also at a regional level in the Indian longitude sector. The data will be immensely helpful to study the low latitude ionospheric disturbances that affect radio communications and navigation capabilities. The instrument is purchased from the financial support of ANRF through Early career grant to Dr Lakshmi Narayanan, Assistant Professor, Environmental Studies, SIAS.
