History

Narrative Summary

The Geological Survey of India (GSI), established in 1851, is a government organization which is an office attached to the Ministry of Mines of the Government of India for conducting geological surveys and studies. GSI is the prime provider of basic earth science information to the government, industry and the general public. In 1965 a separate Department of Airborne Mineral Surveys & Exploration (AMSE) was created in New Delhi by the Government with the objective of utilizing airborne geophysics in mineral resource exploration programmes. In September 1970 AMSE was absorbed into GSI as a specialised Wing. In 1973 the AMSE headquarters moved from New Delhi to Bangalore.

Under Operation Hard Rock, AMSE placed its first contract with a US aerial survey company to produce low-altitude aerogeophysical data during 1967-68. In 1971-72 the Compagnie Generale De Geophysique (CGG) of France was contracted to produce additional data. Further contracts were placed externally until in 1986, AMSE took delivery of its own dedicated aircraft, a DHC-6 Twin Otter. In March 2000 the TOASS sensing system on the aircraft was upgraded to modern standards.

Some time around 2010 ASME was renamed the Remote Sensing & Aerial Surveys (RSAS) Wing of GSI. In 2014 the RSAS took delivery of the first Heliborne sensing system, installed on a HAL Dhruv.

Current Status

The aircraft of the GSI are fully operational.

Future Plans

With continuously increasing demand for survey work, another aircraft may be needed in the near future.

Markings

National Insignia

GSI aircraft are basically white overall, with a red fuselage cheatline that extends up the tail fin. The DHC-6 has full GEOLOGICAL SURVEY OF INDIA service titles on the fuselage sides, while the Dhruv just has the initials GSI.
