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.

ISRO successfully launches fourth navigation satellite IRNSS 1D

Indian Space Research Organization (ISRO) on 28 March 2015 successfully launched fourth navigation satellite Indian Regional Navigation Satellite System (IRNSS)-1D.

It was launched by Polar Satellite Launch Vehicle (PSLV) C-27 into the orbit from Satish Dhawan Space Centre, Sriharikota in Andhra Pradesh.

The satellite is similar to, and follows the IRNSS 1A, 1B and 1C which were launched in April 2013, July 2014 and October 2014respectively.

IRNSS-1D will be launched into a sub Geosynchronous Transfer Orbit (sub GTO). It weighs 1,425 kg and carries a navigation payload and CDMA ranging payload in addition with a laser retro-reflector.

About IRNSS series

  • IRNSS is a navigation system that will cover India, and also extend 1,500 kms from its boundaries.
  • It will provide accurate position information to users in India. Basically it will provide two kinds of services, Standard Positioning Services, which is available to all users, and an encrypted service that is provided only to authorized users.
  • The complete IRNSS system will include three satellites in geostationary orbit and four satellites in geosynchronous orbit at an altitude of 36,000 km above the Earth.
  • The deployment of all the satellites was expected to be completed by 2015 at a cost of Rs. 1,420 cr.

IRNSS is similar to other satellite navigation service providers like USA’s GPS (Global Positioning System), Russia’s Glonass, Europe’s Galileo, Japan’s Quasi Zenith and China’s Beidou.

Applications of IRNSS

  • Terrestrial, Aerial and Marine Navigation.
  • Disaster Management.
  • Vehicle tracking and fleet management.
  • Integration with mobile phones.
  • Precise Timing.
  • Mapping and Geodetic data capture.
  • Terrestrial navigation aid for hikers and travellers.
  • Visual and voice navigation for drivers.
