GSLV Delivers GISAT-1: India's New Earth Observation Satellite
India successfully launched its latest Earth observation satellite, GISAT-1, using the GSLV rocket, enhancing the nation's space-based monitoring capabilities.
Source: GNews ISRO SpaceIndia's Geosynchronous Satellite Launch Vehicle (GSLV-F10) successfully launched the Geo-imaging Satellite-1 (GISAT-1) into a Geosynchronous Transfer Orbit (GTO). The launch took place from the Second Launch Pad at Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. GISAT-1 is an advanced Earth observation satellite designed to provide real-time imaging of large areas of the Indian subcontinent. It will help in continuous monitoring of natural disasters, agricultural activities, and border areas. The GSLV rocket, often called the 'naughty boy' or 'smart boy' of ISRO, performed its mission flawlessly, placing the GISAT-1 satellite precisely into its intended orbit. This mission marks a significant step for India in strengthening its remote sensing infrastructure and strategic surveillance capabilities.
This launch is important for competitive exams, especially for UPSC GS Paper III (Science and Technology) and SSC General Awareness. Aspirants should understand the types of satellites, their applications, and the launch vehicles used by ISRO. GISAT-1's role in disaster management, agriculture, and security highlights the practical applications of space technology, a frequent topic in exams. Knowledge of ISRO's missions and capabilities is crucial for questions on India's scientific advancements.
- GISAT-1 is India's first state-of-the-art agile Earth observation satellite.
- It was launched by the Geosynchronous Satellite Launch Vehicle (GSLV-F10).
- The launch occurred from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota.
- GISAT-1 will provide near real-time imaging of the Indian subcontinent.
- The satellite has a mission life of 10 years.
- It operates from a geostationary orbit, approximately 36,000 km above Earth.
Geo-imaging Satellite-1 is an advanced Earth observation satellite developed by ISRO. It is designed to provide continuous, near real-time imaging of large areas of the Indian subcontinent for applications like disaster monitoring, agriculture, forestry, and national security. It carries a multi-spectral imager.
Geosynchronous Satellite Launch Vehicle is an expendable space launch vehicle developed by ISRO. It is used to launch satellites into Geosynchronous Transfer Orbit (GTO) or Low Earth Orbit (LEO). GSLV rockets are crucial for launching heavier communication and Earth observation satellites.
A geostationary orbit is a circular orbit 35,786 kilometers above Earth's equator, following the direction of Earth's rotation. A satellite in this orbit appears motionless, at a fixed position in the sky, to ground observers. This is ideal for communication and continuous observation satellites.
The Indian Space Research Organisation (ISRO) is the national space agency of India, founded in 1969. Headquartered in Bengaluru, its primary objective is to advance space technology and apply it for national benefit. ISRO is responsible for India's space program, including satellite launches and planetary missions.
UPSC often asks about the applications of ISRO's satellites and the types of launch vehicles. SSC exams frequently test knowledge of ISRO's major missions and their objectives. Focus on the 'what' and 'why' of such launches.
GISAT-1 is like India's 'GI'ANT 'SAT'ellite for 'G'eographic 'I'maging, giving us 'G'ood 'I'nformation.
Frequently Asked Questions
What is the primary purpose of India's GISAT-1 satellite?
The primary purpose of India's GISAT-1 satellite is to provide continuous, near real-time imaging of large areas of the Indian subcontinent. This capability is crucial for applications such as rapid monitoring of natural disasters, agricultural and forestry management, and enhancing national security through border surveillance.
Which launch vehicle was used to put GISAT-1 into orbit?
The Geosynchronous Satellite Launch Vehicle (GSLV-F10) was used to put GISAT-1 into orbit. The GSLV is a three-stage rocket developed by ISRO, specifically designed to launch satellites into Geosynchronous Transfer Orbit (GTO), from where they can be maneuvered into geostationary orbit.
What are the benefits of a geostationary Earth observation satellite like GISAT-1?
A geostationary Earth observation satellite like GISAT-1 offers significant benefits, primarily its ability to provide continuous, real-time coverage of a specific region. This constant vantage point allows for immediate detection and tracking of dynamic events such as weather patterns, natural disasters, and changes in land use, which is vital for timely response and decision-making.
