Brief Description (Abstract):

An experimental low power HF station with a log periodic antenna was installed at Maitri station in December 1991 during the eleventh Indian expedition to Antarctica. Both, voice and PC based data communication were provided between Maitri and India. The communication window was found for a duration of 4 to 5 hours daily except, when due to high magnetic storms there were complete blackouts. This work was undertaken as a joint mission by DEAL and R&D E(E),Pune.

Status: Completed

Purpose: Strong communication link with rest of the world being the backbone of Antarctic research, Indian scientists have addressed themselves to such need and carried out research, especially on High Frequency (HF) communication right since our first venture in that distant continent (Sengupta,1983 Andhere,1985 Hanjura,1986 and Singh,1986). Indian station, Maitri at Antarctica is about 12000 km away from India. HF communication can cover this range without any relay station using multi-hop sky wave mode via ionosphere. The HF communication is possible for a period of 4 to 5 hours every day. There was a long felt need of voice and data communication from Maitri to India. To serve this goal, DEAL, Dehradun set up an experimental HF station at Maitri.
