Science and technology is an important part of the UPSC syllabus. Every year many questions are asked from this section in the IAS exam. Satellites, the ISRO, Indian space program and other current advancements in the field of science and technology are especially important for the UPSC exam.
BHUVAN is a multi-purpose end-user satellite application platform. It is powered by the Indian Space Research Organization (ISRO). This software application allows the users to explore a 2D/3D representation of the surface of the Earth. The browser is specifically tailored to view India, offering the highest resolution in the region. It offers detailed imagery of Indian locations compared to other Virtual Globe Software, with spatial resolutions ranging up to 1 metre. Due to security concerns, the images available do not include any military installations in India. The content is provided in four local languages.
BHUVAN acts as a clearing house for satellite data. It is a humongous software integrating and processing ground inputs with the help of satellite data for various different needs. All the state governments are benefitted by this software application. It experiences about 60 million user hits per month and offers nearly 3.6 lakh products, 800 GB transactions and 10 million data points. The Bhuvan portal is designed to run on slow Internet connections.
