FAQ
1. What role plays ISRO in India in terms of satellite communication?
ISRO is India’s space research organisation. It plays an important role in designing, launching, and operating communication satellites. It developed a number of satellites including the GSAT Series, which provide services such as telecommunications and broadcasting.
2. Satellite internet: How does it work?
Satellite internet uses a geostationary satellite to send and receive data. The ground station transmits the signals to the satellite which relays them back to user’s dish.
3. Satellite communication is a better alternative to terrestrial systems.
Satellite communications offer a wider coverage in areas that terrestrial communication systems can’t reach, such as remote regions. The satellite system is not as vulnerable to disasters. Signal quality remains constant and it can be set up quickly.
4. What steps are taken in India to reduce the space debris?
India focuses its efforts on reducing space pollution by promoting responsible satellite launches, tracking debris and minimizing the amount of it. ISRO explores technologies to remove space debris and improve design practices in order to reduce debris production.
5. Satellite technology is helping to manage disasters in India.
When terrestrial networks are down, satellite technology allows for reliable communication. The satellite technology also allows for real-time monitoring of weather patterns to enable better forecasting, and prompt responses.
6. Is satellite communications used in India for military purposes?
Satellite communications are crucial for military operation, as they provide secure and reliable channels to enable communication, coordination, and surveillance.
7. In India, how are satellites utilized in agricultural practices?
Satellites help in precision agriculture by providing data about weather conditions, soil condition, and crop health. The information provided by satellites helps farmers make more informed decisions when it comes to planting, irrigation, or harvesting.
8. What technologies will be explored for satellite communications in the future?
Quantum communication, which can increase security and speed up internet service, is one of the emerging technologies. Another is satellite miniaturization.
9. In India, how do DTH satellite services work?
Direct-to-Home (DTH) services use satellites to broadcast television signals straight to subscriber’s homes. They allow access to hundreds channels without the need for cable systems.
10. How many satellites has ISRO launched recently?
ISRO’s recent notable projects include the GSAT-30 satellite for communication and the GISAT that monitors Indias weather patterns. These projects increase India’s ability to collect data via satellite and communicate.
