AB: The GPS-Geodesy program initiated in 1995 by establishing a Permanent IGS GPS Tracking station at NGRI has resulted in the estimation of Indian plate motion to be 37 $\pm$2.0 mmy$^{-1}$ towards NNE direction. To understand the tectonic activity and crustal deformation in the south of Indian peninsula, the driving mechanisms and the response of the Indian Ocean Lithosphere and holistically compound the Indian Plate kinematics, NGRI has extended the GPS-Geodesy programme by establishing a permanent GPS station at Maitri, at Antarctica in 1997 in Schirmacher oasis between SANAE and SYOWA. The data from the IGS stations in the islands surrounding Indian plate is included in the global network solution. Very long baselines from Kerguelen, as it is relatively a stable site, to Maitri and other IGS Stations in different plates Casey, Davis, Seychelles, Coco, Hartebeesthoek, Yaragadee, and Tidbinbilla have been estimated. The GPS derived velocity vectors of these sites throw a significant insight into the plausible causes of northward movement of Indian plate. These results also elucidate the strain accumulation processes in the Indian Ocean and the effects of these forces on the Indian Plate.
