Arvi Satellite Earth Station

A commemorative postage stamp on the 1st Anniversary of the Arvi Satellite Earth Station (Vikram Earth Station) :

Map, Satellite and AntennaIssued by India

Issued on Feb 26, 1972

Issued for : The Indian Posts and Telegraphs Department feel privileged in bringing out a postage stamp to commemorate the first anniversary of the earth station at Arvi, which is being dedicated to the nation by the President of India who is also releasing the commemorative stamp. The stamp depicts the “Global Satellite” and the location of the earth station. This station is being named the Vikram Earth Station in memory of the late Dr. Vikram Sarabhai who was primarily responsible for the execution of this sophisticated project by Indian Engineers.

The first day cover being issued on this occasion bears a picture of the antenna at the earth station at Arvi.

Description of Design : The design of the stamp is horizontal and depicts “Global Satellite,” the course of ‘Intelsat III’ in circular lines and ‘Arvi Earth Station.’

About : 

  • The growth of rocketry and space technology during the course of the past decade (1961-1970) has given mankind a new and powerful medium for global communication in the form of satellites, which can relay messages to and from the earth, with the help of the built-in receivers and transmitters. These satellites keep revolving round the earth once in 24 hours at a height of about 36000 kms over the equator, in step with the earth’s rate of rotation on its axis. They thus appear, relatively, to be stationary from any point on the earth. One such satellite can cover nearly a third of the globe, while three of them suitably distributed can cover the entire globe.
  • Unlike conventional high frequency radio communication which works point to point, satellites link all earth stations in their area of coverage. This is possible on account of the wide-band capability of satellite radio relay systems.
  • Satellites permit voice, telegraphs radio-photo and data to be relayed with ease between stations in their area of coverage. They are also the only existing means of live transoceanic television. Already many historic events have been viewed live on television via satellites by millions of viewers in several continents.
  • Satellite communication is not subject to fading or atmospheric disturbances which are limitations of H.F. radio communications. It can provide the requisite high quality circuits to meet the challenging demands of ever-expanding international communications.
  • Satellite communications has verily opened up a new era of international cooperation which commenced with the setting up of Intelsat, the International Satellite Consortium, in 1964. This Consortium today has 77 member nations. India‘s participation in this international venture dates back to February, 1965 when its representative signed at Washington the agreements of the International Consortium.
  • While the launching of the satellites and associated tracking and telemetering will be the responsibility of the Intelsat, each member country will be required to establish its earth station to work to the satellite. Accordingly a plan for the establishment of an Indian earth station and associated switching complex was drawn up as a part of the Fourth Five Year Plan of Govt. of India for Overseas Communications Service, to provide the public with up-to-date facilities for international telecommunications, including international TV relay.
  • The earth station is located at Arvi about 80 kms north of Poona on the route to Nasik. This station works to the Indian Ocean satellite, which is located over the equator at a nominal longitude of 61.4″E. The earth station has been inter-connected with Bombay by a broad-band microwave link across the Western Ghats. Bombay serves as the gateway centre of the country for international telecommunications via satellite.
  • The main feature of the earth station is its large 29.6 metre diameter antenna, looking at the satellite over the Indian Ocean. Since the order of power transmitted by the satellite is as low as a few watts and a large distance separates the satellite from the earth station, very large size antennas are required to be used on ground. The same antenna is also used for transmitting to the satellite. The antenna dish at Arvi was manufactured in India.
  • Communication circuits have been established through Arvi earth station with AustraliaJapan, East Africa, Malaysia and United Kingdom via the satellite. Satellite circuits are extended to U.S.A. and Europe via U.K. Further expansion to cover more earth stations via satellite is expected in due course.

I worked in Arvi during 1974-1977 as Tech asst. Wonderful station. I will be happy if someone posts the present status of this station. My work here helped me to progress as sr. Scientist in DRDO later.Thankful to VSES, OCS,Arvi.
