Test: Indian Satellites - UPSC MCQ

The Indian National Satellite System (INSAT) series consists of a group of multipurpose geostationary satellites launched by ISRO to provide telecommunication, broadcasting, meteorology, and search-and-rescue services in India.

Aryabhata was India's first satellite, launched on April 19, 1975, from the Soviet Union. It was an experimental satellite intended to conduct scientific experiments in X-ray astronomy and solar physics.

The CARTOSAT series of satellites are dedicated to providing high-resolution earth observation and remote sensing data for cartographic applications, urban planning, and rural development.

RISAT-2 (Radar Imaging Satellite-2) is known as the "Eye in the Sky" because it is equipped with an all-weather, day-and-night synthetic aperture radar, which enables it to capture images even in adverse weather conditions.

The IRNSS (Indian Regional Navigation Satellite System) series, also known as NavIC, consists of a constellation of satellites developed by India to provide accurate positioning and timing information over the Indian region and the surrounding area.

Chandrayaan-1 was India's first lunar probe launched in 2008. It was designed to study the moon's surface and carry out experiments on lunar mineralogy, chemistry, and topography.

GSAT-11 is a high-throughput communication satellite that operates in the Ku-band frequency range. It is designed to provide broadband services across India.

Mars Orbiter Mission, also known as Mangalyaan, was India's first interplanetary mission launched to study the Martian atmosphere, surface, and mineralogy.

Chandrayaan-2 was launched using the GSLV Mk III-M1 rocket, ISRO's most powerful launch vehicle at the time of the mission.

GAGAN (GPS Aided GEO Augmented Navigation) is India's satellite-based augmentation system, which provides enhanced accuracy and reliability of GPS signals for civil aviation and other critical applications.

GSAT-15 operates in a geostationary orbit, which means it remains fixed relative to the Earth's surface and provides continuous communication services.

The Satish Dhawan Space Centre (SDSC) located in Sriharikota, Andhra Pradesh, is the primary launch site for Indian satellites.

The first satellite of the Indian Regional Navigation Satellite System (IRNSS), also known as NavIC, was launched in 2013.

GSAT-17 is a communication satellite equipped with transponders that are used to monitor the movement of ships in the Indian Ocean Region (IOR).

The "South Asia Satellite," also known as GSAT-9, was launched to provide communication and disaster management support to the neighboring countries of Bangladesh, Bhutan, and Nepal.

RISAT-1 (Radar Imaging Satellite-1) is primarily used for earth observation using synthetic aperture radar (SAR) imaging, which allows it to capture high-resolution images of the Earth's surface even in adverse weather conditions.

Astrosat is India's first dedicated multi-wavelength space observatory launched to study various cosmic sources such as stars, galaxies, and black holes, as well as celestial objects in different wavelengths of light.

Cartosat-3 is capable of capturing high-resolution images with a ground resolution of 10 centimeters, making it one of the most advanced remote sensing satellites in India's fleet.

INSAT-4B was primarily launched to provide direct-to-home (DTH) television broadcasting services across India.

GSAT-6A encountered communication loss during its orbit raising operations in 2018 due to a power system failure in the satellite.
