GIRI Radar System Has Been Established by ISRO near Tirupati [ Current News (Concise) ]
The Gadanki Ionospheric Radar Interferometer (GIRI) Radar System has been installed by the Indian Space Research Organization (ISRO) near Tirupati, Andhra Pradesh. It was installed at the autonomous research institute of the Department of Space (DoS) a National Atmospheric Research Laboratory (NARL).
Features of GIRI Radar System:
- Transfer unattended observations for studying the forcing from the sun like variation in solar flare, solar flux and magnetic storm on the ionospheric irregularities.
- Study unattended clarifications from the beneath atmosphere on the ionospheric irregularities (for e. g. waves generated by weather phenomena).
- Provide important information about the angular location of plasma irregularities during the onset phase.
- Also found its relationship to background ionospheric state limits and sunset terminator.
- Inquiries made using this system are predictable to improve the Equatorial Plasma Bubble (EPB) predicting.
- And latter it will be disadvantageous for satellite based navigation/communication applications.
- The GIRI has a 30 MHz radar system that will be complicated in meteor and space weather research.
- It consists of a quadrangular antenna array of 160 two-element Yagi Uda-antenna.
- It will be organized in a 20×8 matrix with 20 transmitter units.
- It also has 6 digital receivers including data processing systems, a host computer and a radar controller.
