Brief Description (Abstract):

Observations made at the Indian station Maitri in East Antarctica during the period spanning between July 1992 and January 1993, reveal that the state of HF communication between India and Antarctica is greatly dependent on the electromagnetic state of Earth's environment (as depicted by magnetograms). It is noticed that the radio signal intensity is also dependent on season. Present work reports on some of these observations.

Status: Completed

Purpose: A high frequency (HF) radio link has been operating between India and Antarctica right since 1984, the very first year of wintering at Dakshin Gangotri (DG with geographic coordinates 70?05S12?00E). The same has been continued from the present station Maitri (MAI with geographic coordinates 70?46S 11 ?45E) since 1989.During 1992, the radio frequencies used between Maitri and Delhi (DEL with geographic coordinates 28?42N77?20E) were 16.94 MHz and 14.450 MHz. The link was regularly operated by the Indian avy for a few hours centred around noon every day at MAI. Over the period July 1992 to January 1993, the Indian Institute of Geomagnetism in collaboration with the Indian Navy, kept a close watch on the state of this HF radio link in terms of amplitude and quality of radio signal between MAI-DEL, in both the forward and reverse directions. These observations were compared with the magnetograms recorded at MAI.
