Brief Description (Abstract):

During the Tenth Indian Scientific Expedition to Antarctica, geodetic and geophysical controls were established in the area of Schirmacher Oasis and its surrounding nunataks, for map making and future scientific explorations. 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.

Status: Completed

Purpose: 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.
