Sub-sonic Cruise Missile ‘Nirbhay’ Successfully Test-Fired

India’s first indigenously designed and developed long-range sub-sonic cruise missile ‘Nirbhay’ from a test range Chandipur, Odisha.

Nirbhay Missile

  • Nirbhay missile has blended missile and aeronautical technologies which allows it to take off vertically like missile and cruise horizontally like an aircraft.
  • The missile has a two-stage missile powered by solid rocket motor booster developed by Advanced Systems Laboratory (ASL).
  • Nirbhay Missile has an operational range of 1000 km and can carry warheads of up to 300 kg including nuclear warheads.
  • It can be launched from various kind of platforms.
  • It can travel with a turbofan or turbojet engine and is guided by a highly advanced inertial navigation system.
  • It has the capability to loiter and cruise at 0.7 Mach, at altitudes as low as 100m.
  • It is terrain hugging missile which keeps on encircling the area of its target for several minutes and then hits bull’s eye’ on an opportune time.
  • It is difficult to detect by enemy’s radars. It is capable to engage several targets in a single flight.
  • The guidance, control and navigation system of missile is configured around indigenously designed Ring Laser Gyroscope (RLG) and MEMS-based Inertial Navigation System (INS) along with GPS system.

It was the sixth experimental test of Nirbhay missile system and it achieved all mission objectives right from lift-off till the final splash, boosting the confidence of all scientists associated with the trial.

GSI Sets Up 22 GPS Stations across Country

The Geological Survey of India (GSI) has launched 22 permanent global positioning system (GPS) stations across India to identify seismically hazardous zones and encourage mapping activities.

These 22 stations are part of the 35 stations planned by GSI to establish and maintain a network of continuously operating 35 permanent GPS stations.

Fact Box: Bhuvisamvad

Bhuvisamvad is an app launched by the Ministry of Mines to facilitate interaction between geo-scientists and university and college students.

GPS stations

22 stations inaugurated are based at Kolkata, Thiruvananthapuram, Jaipur, Pune, Dehradun, Chennai, Jabalpur, Bhubaneswar, Patna, Raipur, Bhopal, Chandigarh, Gandhinagar Vishakhapatnam, Agartala, Itanagar, Mangan, Jammu, Lucknow, Nagpur, Shillong and Little Andaman.

13 More Stations Would come up at Aizawl, Faridabad, Uttarkashi, Pithoragarh, Cooch Behar, Zawar, North Andaman, Middle Andaman, South Andaman, Ranchi, Mangalore, Imphal and Chitradurga.

These stations are meant to delineate high strain zones for earthquake probability, determine a seismic motion on faults that may lead to a rupture and produce thematic maps with high positional accuracy.

Geological Survey of India

Geological Survey of India (GSI) was established in 1851 primarily to find coal deposits for the Railways. Over the years GSI  has not only grown into a repository of geoscience information required in various fields in the country but has also attained the status of a geo-scientific organisation of international repute.

The main functions of GSI attached to the Ministry of Mines is to create and update of national geoscientific information and mineral resource assessment through ground surveys, airborne and marine surveys, mineral prospecting and investigations, multi-disciplinary geoscientific, geotechnical, geo-environmental and natural hazards studies, glaciology, seismotectonic study, and carrying out fundamental research.
