Brief Description (Abstract):

The communication team of the XVI Antarctic expedition took up the task of establishing the first ever picture transmission link betweeen Antarctica and India over a band-limited telephone channel. The link was set up between the MAITRI Station and the Prime Minister's residence at New Delhi on 26 January 1997 when inaugural pictures of the installation of the bust of Mahatma Gandhi at the Indian Antarctic Station MAITRI were transmitted in near realtime to the Prime Minister in India. In this describes the techniques and the steps involved in engineering the picture transmission link using a portable INMARSAT satellite terminal. The authors also highlight the problems and limitations associated in working at the fringe areas of INMARSAT footprint.

Status: Completed

Purpose: Rapid advancements in satellite technology have made it possible to provide reliable and effective communication under stressed conditions from a remote place like Antarctica. The geographical location of the MAITRI station near the South Pole makes it difficult to fully exploit satellites in equatorial orbits for communication purposes. The INMARSAT satellite, whose designated footprint spans upto 70 South latitude is the only path for providing long-distance telephone circuits from Antarctica. Traditionally, the INMARSAT portable terminal at Antarctica has been used to handle voice traffic alongwith E-mail applications. However, in recent times, the availability of faster desktop PCs along with improvements in video compression techniques have made it possible to transmit pictures over existing band-limited telephone circuits.
