Which one of the following is a communication satellite?

Appeared in: AIIMS BHOPAL NO- 2018( Shift-2nd)

Explanation

GSAT-17 is a geostationary communication satellite developed by the Indian Space Research Organisation (ISRO).
Its primary purpose is to provide continuity of various communication services in C-band, Extended C-band, and S-bands.
These services include telecommunication, television broadcasting (like Direct-To-Home or DTH), and satellite news gathering.

Option A: KALPANA-1 is a meteorological satellite, not a communication satellite.
Option C: ScatSat-1 is a weather forecasting satellite that measures ocean wind vectors.
Option D: SARAL is an oceanographic satellite used for altimetry studies.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Types and functions of Indian satellites as background academic context rather than a clinical decision trigger.
Satellite communication is the backbone of modern telemedicine, enabling specialist consultations for patients in remote and underserved areas where terrestrial internet is unavailable.
During natural disasters, when terrestrial communication networks fail, satellite-based systems are crucial for coordinating emergency medical response and relief efforts.
What if a disaster management team needs to establish a field hospital in a cyclone-hit coastal area with no mobile network? They would rely on a communication satellite link (like GSAT) for data transfer and communication, not a weather satellite like ScatSat-1, whose data would have been used to predict the cyclone beforehand.

How to Approach the Question

First, identify the key term in the question: 'communication satellite'.
Next, review the given options, which are names of specific Indian satellites.
Recall the primary function associated with different ISRO satellite series. The 'GSAT' (Geosynchronous Satellite) series is specifically designated for communication.
Recognize that KALPANA-1 and ScatSat-1 are associated with meteorology (weather), and SARAL is an acronym related to ocean studies (ARgos and ALtiKa).
Based on this classification, select GSAT-17 as the satellite whose primary purpose is communication.
