India’s First ‘Smart Fence’ Pilot Project Inaugurated

Union Home Minister Rajnath Singh inaugurated two “smart” border fencing pilot projects under the Comprehensive Integrated Border Management System (CIBMS) programme at Jammu’s International Border (IB). These two pilot projects under CIBMS will go a long way in strengthening border security infrastructure. The project is touted to be the government’s important measure in border security. Each of two newly inaugurated border fencing projects covers a 5.5 km stretch along the international border. The system is said to be a first-of-its-kind high-tech surveillance system that will create an invisible electronic barrier on land, water, air and underground. This will help BSF detect and foil infiltration bids.


ISRO’s PSLV-C-42 Launches Two U.K. Satellites

The NovaSAR and S1-4 earth observation satellites were launched in Andhra Pradesh’s Sriharikota. The PSLV-C42 launch vehicle, which carried both space satellites, blasted off from the first launchpad at Satish Dhawan Space Centre. PSLV-C-42 is the lightest version of the PSLV (Polar Satellite Launch Vehicle). NovaSAR is intended to be used for forest mapping, land use and ice cover monitoring, flood and disaster monitoring. The S1-4 will be used for environment monitoring, urban management, and tackling disasters. The launch comes almost six months after ISRO successfully placed the INRSS-1I navigation satellite in orbit.


ISRO Unveils Polarimetry Doppler Weather Radar At Sriharikota Spaceport

The Indian Space Research Organisation (ISRO) inaugurated the Polarimetry Doppler Weather Radar at Sriharikota spaceport near Chennai. The S–Band Polarimetry Doppler Weather Radar facility was launched at Satish Dhawan Space Centre, Sriharikota by Isro Chairman Dr K Sivan. The radar has been developed by Bharat Electronics Ltd, Bengaluru under ToT (Training of Trainers) from ISRO. The Doppler Weather Radar (DWR) provides advanced information, enhances the lead-time essential for saving lives and property in the event of a natural disaster associated with severe weather. While conventional radars are able to track and predict cyclones, the DWR provides detailed information on a storm’s internal wind flow and structure. The severity of the weather systems can be quantitatively estimated and more precise advanced warnings can be generated for saving human lives and property.  The polarimetric capability of the radar will significantly improve the accuracy of rainfall estimation leading to accurate and timely flash flood warnings.
