Arvi Satellite Earth Station

The development of rocketry and space technology over the past decade has revolutionized global communication through the use of satellites. These satellites, equipped with built-in receivers and transmitters, orbit the Earth approximately once every 24 hours at an altitude of about 36,000 kilometers above the equator, synchronizing with the Earth’s rotation on its axis. This Arvi Satellite Earth Station positioning allows satellites to cover large areas of the globe, with just one satellite covering nearly a third of the Earth’s surface, and three satellites strategically placed providing global coverage.

Unlike conventional high-frequency radio communication, which operates point-to-point, satellite links connect all stations within their coverage area. This is made possible by the wide-band capability of satellite radio relay systems, enabling the transmission of voice, telegraphy, radio-photography, and data between stations. Satellites also facilitate live transoceanic television broadcasts, allowing millions of viewers across continents to witness historic events in real-time.

Satellite communication offers several advantages over traditional radio communication, such as immunity to fading and atmospheric disturbances, ensuring high-quality communication circuits for expanding international communication needs. The establishment of Intelsat, the International Satellite Consortium, in 1964 marked the beginning of a new era of international cooperation in satellite communication, with 77 member nations participating, including India since February 1965.

As part of India’s commitment to international satellite communication, an earth station and associated switching complex were established in Arvi, located about 80 kilometers north of Pune. This earth station, named the Vikram Earth Station in memory of the late Dr. Vikram Sarabhai, serves as a gateway for international telecommunications via satellite. Equipped with a large 29.6-meter diameter antenna, the Arvi earth station facilitates communication circuits with countries across the globe, including Australia, Japan, East Africa, Malaysia, and the United Kingdom, with further extensions planned for the future.

The Indian Posts and Telegraphs Department commemorates the first anniversary of the Arvi earth station by issuing a postage stamp, which depicts the “Globe Satellite” and the location of the earth station. This station stands as a testament to Indian engineering prowess and Dr. Vikram Sarabhai’s vision for advancing satellite communication technology. The First Day Cover accompanying the stamp features a picture of the antenna at the Arvi earth station, highlighting its importance in India’s journey towards enhanced global connectivity.
