The Asian satellite arc slots refer to a series of orbital positions over the Equator that are used by satellites to broadcast television, radio, and other communication services to countries in the Asian-Pacific region. These slots are highly sought-after due to their strategic location, which allows satellites to reach a vast audience across the region. In this article, we will provide an in-depth overview of the Asian satellite arc slots, including their history, availability, and importance in regional communications.
The concept of the Asian satellite arc slots emerged in the 1960s with the launch of the first geostationary satellites. These satellites were placed in orbit at a height of 35,786 kilometers above the Earth's surface, which allows them to rotate at the same speed as the Earth, making them appear stationary from the ground. The International Telecommunication Union (ITU) established the International Satellite Frequency Coordination Committee (IFSCC) to manage the allocation of orbital slots and prevent interference between satellites.
The ITU has allocated a total of 125 degrees of orbital arc to the Asian region, divided into 15 degree intervals. Each of these intervals is further subdivided into 36 frequency slots, totaling 4,500 slots for the entire arc. The slots are distributed among countries in the region based on their population, economic development, and communication needs.
However, the demand for satellite slots has outpaced the available supply, leading to increased competition and the emergence of a secondary market for slot leasing. According to the Asia-Pacific Telecommunity (APT), there is a waiting list of more than 100 satellite operators seeking slots in the Asian arc.
The Asian satellite arc slots play a crucial role in regional communications. They provide essential services such as:
