Global Positioning System (GPS) receivers were used in the icy continent by the Survey of India (SOI) scientists for establishing the precise positions of the selected locations. Map making and exploration need accurate estimation of position. This is nowhere more true, than on the vast and monotonous expanse of ice of Antarctica with its few oasis and isolated nunataks. Establishing a positional fix in the hostile weather conditions of this icy continent poses a challenge for surveyors engaged in position fixing and surveys. Normal classical methods, viz. triangulation, traverse and trilateration are not suitable due to strong winds and blizzards which are a common phenomenon in this region. The use of electromagnetic instruments is not advisable because of frequent magnetic storms which adversely affect the instrumentation of such equipment. Giant strides in Space Geodesy and the capabilities of instrumentation, have now made it possible to venture in such hostile areas for map making and exploration. The development of GPS technology has the capability to give precise position fixing, required to provide vital control points for map making. completed principalInvestigator National Centre for Polar and Ocean Research (NCPOR) 8322525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND ictd@ncpor.res.in Dr. V P Srivastava 20.0 140.0 -90.0 30.0 1990-01-01 1991-12-31 Earth Science-Land Surface Theme Maitri Antarctic Place Geographical Control in East Antarctica Project eng TableDigital unknown unknown unknown distributor National Centre for Polar and Ocean Research (NCPOR) +91-832-2525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND vssamy@ncpor.res.in Mr. Sakthivel Samy V http://npdc.ncaor.gov.in/npdc/search_mf_data.action?search=freeText&expedition_type=all&parameter=MF-353493190&userType=user&freeTextValue=Geographical+Control+in+East+Antarctica.
