Pakistan television wants to launch and news channel across the world explain how many minimum number of geostationary satellites have been refer my suparco for entire coverage of the earth and why
To achieve entire coverage of the Earth for a news channel, a minimum number of three geostationary satellites are required. This is because geostationary satellites are positioned at an altitude of about 36,000 kilometers above the Earth's equator and rotate at the same speed as the Earth's rotation, resulting in them appearing stationary from the ground.
To cover the entire Earth, the three satellites would need to be positioned at different longitudes spread evenly around the globe. By spacing them approximately 120 degrees apart, they can provide coverage for the entire surface of the Earth, including both the land and oceans. This configuration ensures that at least one satellite will always have a line-of-sight connection to any point on the Earth's surface, providing continuous and uninterrupted coverage.
Suparco, the Space and Upper Atmosphere Research Commission of Pakistan, may recommend a minimum of three geostationary satellites due to the following reasons:
1. Global Coverage: By utilizing three satellites, Suparco can effectively cover the entire Earth, including remote areas that might not be accessible through other means of transmission. This ensures that the news channel would be able to broadcast news and events from any part of the world.
2. Redundancy: Having multiple satellites offers redundancy and ensures that even if one satellite experiences technical difficulties or requires maintenance, the other two can continue transmitting broadcasts seamlessly. This redundancy minimizes downtime and avoids interruption of news coverage.
3. Load Distribution: Sharing the broadcasting load among multiple satellites helps prevent congestion and ensures smooth transmission and reception of signals. Additionally, it allows for efficient allocation of resources across the coverage area.
By having at least three geostationary satellites in different positions in the geostationary belt, Pakistan Television's news channel can provide comprehensive and uninterrupted coverage of the Earth, ensuring that viewers across the globe have access to news and events occurring anywhere around the world.
