The Space pioneer of India ISRO has established the Gadanki Ionospheric Radar Interferometer (GIRI) near Tirupati in Andhra Pradesh.
Located at: National Atmospheric Research Laboratory (NARL) which is an autonomous research institute of the Department of Space
Construction: It consists of a rectangular antenna array of 160 two-element Yagi-antenna, arranged in a 20×8 matrix, 20 transmitter units, 6 digital receivers including data processing systems, a radar controller, and a host computer
- To carry out unattended observations towards studying the forces from the sunlike variation in solar flux, solar flare and magnetic storm on the ionospheric irregularities
- To studyunattended observations from the underneath atmosphere (e.g., waves generated by weather phenomena) on the ionospheric irregularities.
- It will provide important information on the angular location of plasma irregularities during the onset phase
- The info provided will be used to improve the skill in Equatorial Plasma Bubble (EPB) forecasting which is detrimental for satellite based navigation/communication applications.
- Autonomous body of Department of Space research at Gadanki, Tirupathi
- World’s first low latitude laboratory
