Introduction Global positioning system (GPS) is also known as Navigation System with Time And Ranging Global Positioning System (NAVSTAR) GPS. It is a GNSS (global satellite-based navigation system) system that covers the entire earth. GPS was originally developed for military purposes, but after some time it is being used by civilians for various purposes such … Read more
Introduction Remote sensing is the science of collecting information about any object on a surface from a well-defined distance with a proper sensor. In general, it may define as a technique of gathering data of the surface of the earth from a distance with a sensor mounted on a moving platform. Remote sensing can be … Read more
What is NASA’s DART (Double Asteroid Redirection Test) Mission? The Dart (Double Asteroid Redirection Test) mission is one of the future-oriented projects of NASA in which NASA aims to hit an asteroid to adjust its speed and path of orbit. DART will be the first-ever space mission to demonstrate asteroid deflection by the kinetic impactor. … Read more
What is Space Debris? Since the massive development in the field of space technology in the late 1950s, we have launched several thousands of different category satellites (low earth orbital, medium earth orbital, and high earth orbital satellites) in the earth orbit. Many of those are still working and some are not, the number of … Read more
The Himalayas(In Fact) The Himalayas, or Himalayas (Hima “snow”, aa-laya “dwelling”, “dwelling”), are a mountain range in Asia that separates the plains of the Indian subcontinent from the Tibetan Plateau. The mountain range contains some of the highest peaks on the planet, including the tallest, Mount Everest. More than 100 peaks above 7,200 meters (23,600 … Read more
What is Mountain? A mountain is an elevated portion of the earth’s crust, ordinarily with steep sides that demonstrate a significantly exposed cornerstone. A mountain differs from a plateau in a limited summit area and is larger than a hill, which usually rises at least 300 meters (1,000 ft) above the surrounding land. Some mountains have individual … Read more
What is UNFCCC The UN Framework Convention on Climate Change (UNFCCC) was signed in 1992 during the United Nations Conference on Environment and Development, generally known as the Earth Summit, the Rio Summit, or the Rio Conference. The UNFCCC entered into force on 21 March 1994. Today, it has near-universal membership. The 197 countries that … Read more
A brief history of Remote Sensing The beginning of remote sensing starts from capturing aerial photography with the help of balloons, kites, pigeons, and gliders. In late 1908 after the development of operational aircraft, the first functional aircraft was used for aerial photography. During World War I and II the aerial photographs were used as … Read more
At present, one of the most powerful instruments for the study of climate change ecology, land use land cover changes, ocean temperature, and salinity, and forest application is satellite remote sensing, which measures the flow of radiation entering and exiting the upper atmosphere. After 1962, the term “remote sensing” became popularized, and it typically refers … Read more
Introduction- Cyclones are the most terrible storms on Earth. A cyclone is a system of counter-clock-wise circulation of winds around a core of low pressure (eye of a cyclone) in the Northern Hemisphere and opposite conditions in the southern hemisphere winds move clockwise direction around the eye of the cyclone (due to Coriolis effect). Moving … Read more
