Why is it in the news?
- The Ministry of Tribal Affairs plans to partner with the Indian Space Research Organisation (ISRO) to deploy V-SAT stations on a pilot basis.
- The initiative aims to provide internet services to approximately 80 tribal villages located in geographically remote and challenging areas that have lacked connectivity for an extended period.
| About V-SAT (Very Small Aperture Terminal)
· V-SAT is a two-way satellite ground station equipped with a dish antenna ranging from 75 cm to 1.2 meters in size. · Facilitates two-way communication via satellite, relaying data between small remote Earth stations (terminals) and other terminals or central Earth station hubs. · Capable of handling both narrowband data (e.g., credit card transactions, polling) and broadband data (e.g., satellite internet access, VoIP). · Used to provide connectivity to remote locations, support transportable or on-the-move communications, and enable mobile maritime communication. Advantages of V-SAT: · No physical network needed, reducing the risk of structural issues and eliminating the need for extensive infrastructure. · Can operate independently, serving as a backup for wired networks in case of failure. · Easy deployment in remote locations with minimal infrastructure requirements. Disadvantages of V-SAT: · Latency issues due to the time delay in signals traveling between space and the ground, particularly noticeable in two-way communication. · Signal quality may be affected by weather conditions and obstructions like buildings or trees, causing signal distortion between the satellite and earth station.
