Activities using the Indian National Satellite (INSAT) system:
Weather forecasting:
- The INSAT system is used for monitoring weather patterns, collecting meteorological data, and providing accurate weather forecasts to help in disaster management and agricultural planning.
Search and Rescue operations:
- INSAT satellites are equipped with transponders that can receive distress signals from emergency beacons on ships, aircraft, or individuals in distress, enabling quick and efficient search and rescue operations.
Navigation:
- The INSAT system can provide navigation services by transmitting signals that are used for determining the position, velocity, and time for various applications including maritime navigation, aviation, and surveying.
Television broadcasting:
- INSAT satellites are widely used for television broadcasting, enabling the transmission of TV channels across India and neighboring countries, as well as relaying educational and informational programs to remote areas.
In conclusion, the Indian National Satellite (INSAT) system can be utilized for all four activities mentioned - weather forecasting, search and rescue operations, navigation, and television broadcasting. Its versatile capabilities make it a valuable asset for various sectors including meteorology, emergency services, transportation, and communication.
How many of the following activities can use the Indian National Satel...
- The Indian National Satellite (INSAT) system is one of the largest domestic communication satellite systems in Asia-Pacific region with nine operational communication satellites placed in Geo-stationary orbit. Established in 1983 with commissioning of INSAT-1B, it initiated a major revolution in India’s communications sector and sustained the same later.
- The INSAT system with more than 200 transponders in the C, Extended C and Ku-bands provides services to telecommunications, television broadcasting, satellite newsgathering, societal applications, weather forecasting, disaster warning, and Search and Rescue operations.
- While not a primary navigation system, INSAT can provide augmentation to satellite-based navigation systems. It offers location and timing information to enhance navigation accuracy in applications such as civil aviation and maritime navigation. GSAT-8 / INSAT-4G is an Indian Ku-band satellite carrying 18 transponders similar to that of INSAT-4A and INSAT-4B. It carries 2 BSS transponders and a GAGAN (Navstar Aided Geo Augmented Navigation) payload (satellite navigation for aviation). The satellite was originally planned to be launched during 2008-09, but was postponed until 2011.
- GSAT-7 or INSAT-4F is a multi-band military communications satellite developed by the Indian Space Research Organisation. Hence option (d) is the correct answer.
